Caio Dissertação Mestrado (Versão FINAL).pdf: 6456975 bytes, checksum: cb47f45f811eedcbb8b5288fd76f3f06 (MD5)<br>A Bacia de Jacuípe é considerada uma bacia de nova fronteira localizada no Nordeste
Brasileiro, na margem passiva leste, e estritamente offshore. Acredita-se que ela tenha um
grande potencial para jazidas de hidrocarbonetos. Entretanto, há uma grande carência em
estudos integrados que auxiliem no seu entendimento. O presente trabalho visa compreender a
história evolutiva da bacia através da interpretação de sequências de segunda e terceira ordens
em dados de sísmica de reflexão. A partir da interpretação de 40 perfis sísmicos 2D e do
único poço perfurado, que encontra-se na região de plataforma, os autores puderam
caracterizar importantes eventos dentro da bacia. Dentro da supersequência rifte foram
reconhecidas quatro sequências deposicionais nomeadas Rift 1, Rift 2, Rift 3 e Rift 4,
limitadas por três limites de sequência. Os riftes 1 e 2 têm deposições isoladas ao longo da
bacia e as falhas sintéticas e antitéticas destas fases começam um processo de conexão. O Rift
3 tem a maior representatividade na bacia e seus depósitos cobrem a maior parte dela. O Rift
4 representa o fim da subsidência mecânica com menores expressões nos falhamentos e
experimentou um soerguimento, o qual levou a atual plataforma continental a ficar exposta
durante eventos subsequentes. A supersequência Drift foi subdividida em dois estágios drifte.
Uma vez que a bacia sofreu um soerguimento ao final do seu rifteamento, o primeiro estágio
do drifte tem o preenchimento sedimentar confinado ao talude e ao sopé continental.
Enquanto que no segundo estágio do drifte a sedimentação ultrapassa a falha de borda e seus
depósitos se sobrepõem à supersequência rifte na plataforma. Um mapa estrutural de falhas
foi construído para a porção sul da Bacia de Jacuípe destacando os principais controles do
falhamento, a linha de charneira da bacia, principais depocentros, o Alto Externo de Jacuípe e
um alto vulcânico. O limite geográfico a sul com a Bacia de Camamu foi definido em uma
zona complexa de falhas de transferência e de alívio, caracterizando assim, um limite
geológico. Adaptações foram sugeridas para uma nova carta cronoestratigráfica para a porção sul da Bacia de Jacuípe.<br>ABSTRACT
Jacuípe Basin is considered a new frontier basin in the northeastern Brazilian passive
margin. It is believed it has a great potential for hydrocarbon plays and leads. However, it
lacks in integrated studies for its understanding. The present paper aims to comprehend the
evolutionary history of such basin through seismic reflection analysis of second and third
orders sequences. With the interpretation of several 2-D seismic profiles and a well drilled on
the platform the authors were able to distinguish important events within the basin. Within the
rift supersequence it was recognized four sequences named as Rift 1, Rift 2, Rift 3 and Rift 4,
limited by three sequence boundaries. Rifts 1 and 2 have scattered depositions and the
synthetic and antithetic faults start a linkage process. Rift 3 has a wide spread representation
throughout the basin covering most part of it. Rift 4 makes up the termination of mechanical
subsidence with minor expression in faulting and has experienced an uplift whose led the
currently continental shelf to be exposed most part of subsequent events. Drift supersequence
was split in two drifting stages. Inasmuch as basin has undergone an uplift, the first drift stage
has sedimentation confined to slope and rise regions. Whereas in the second drift stage
sedimentation surpasses the border fault and its successions overlie directly rift supersequence
in platform. A structural faulting map was built for southern Jacuípe Basin depicting main
faulting controls and trends, basin hinge line, main depocenters, the Jacuípe External High
and a volcanic plug. The geographic southern boundary with Camamu Basin was set up at a
complex zone of transfer and release faults, making up a geologic limit. Adaptations were
suggested for a new chronostratigraphic chart for southern Jacuípe Basin.

Full textAbstract:
This study provides a sequence stratigraphic framework within which to consider Brigantian Yoredale strata. The framework has been used to determine the relative effects of syn-depositional tectonics, eustasy and climate on Yoredale sequence stratigraphic architecture within the northern Britain study area. Seventeen high-frequency depositional sequences have been identified and correlated within Brigantian strata in northern England and the Midland Valley of Scotland. Examination of sequence thickness and lithofacies stacking patterns has allowed the spatial and temporal occurrence of syn-depositional tectonism to be constrained and the effects on sequence and lithofacies architecture defined. The overall effect of tectonics on Yoredale sedimentation and cyclicity are interpreted to have been minimal. The correlation of sequence boundaries between the two very different tectonic regimes of northern England and the Midland Valley of Scotland would suggest that tectonics was not the driving mechanism behind cyclicity as suggested by some workers. Correlation of sequences with coeval sequences in the Illinois Basin of mid-continent North America demonstrates a lack of correlation to a particular tectonic regime or depositional facies type. The close similarity of sequence architecture between the Illinois Basin and northern British basins is taken to indicate that the sequences were synchronous depositional events that resulted from high-frequency eustatic sea-level changes. Glacio-eustasy provides the most logical explanation for the observed sequence architecture and apparent synchronous development of sequences and sequence boundaries across the northern Britain study area and globally.

Full textAbstract:
The Lower Jurassic stratigraphy of seven contrasting areas in western Europe is compared in order to seek evidence for a pan-Western European stratigraphic forcing mechanism. Sequencestratigraphic models are discussed and emphasis is placed upon the differing response of sedimentary systems in "accommodation space-dominated" and "supply-dominated" settings. Spectral gamma-ray data from clastic successions in the Wessex and Cleveland basins (England) are used to elucidate vertical trends. A proximal-distal model for control of Th/K ratios is advanced. Stage-frequency regressive-transgressive cycles in the two areas are shown to be closely correlative. Sedimentolgical logs and spectral gamma-ray data are presented for the carbonate ramp into turbidite sequence of Peniche (Portugal) and for a new exposure of the Pliensbachian-Toarcian in southern Germany. Systematic variation in clay mineralogy across Europe is suggested. Cycles in the Lower Jurassic of the North Viking Graben (Norwegian North Sea) are examined using wireline log correlation and the stratigraphic evolution of the Tethyan Rift in the Western and Southern Alps is reviewed. X-ray diffraction studies of the Pliensbachian-Toarcian interval in the Southern Alps are presented in order to elucidate sediment supply to the pelagic realm. The cycles observed in the English sections appear to be manifest widely across western Europe in a variety of tectonic and sedimentary settings. Sharp basinward facies shifts (candidate sequence boundaries) do not appear to be synchronous between basins. <sup>87</sup>SR/<sup>86</sup>SR analysis of belemnites from the Portuguese and German sections confirms the regional applicability of the results of Jones (1992) and the utility of this technique in long range correlation. Carbon and oxygen analysis of the same material supplements the data of other workers and a direct relationship is suggested between relative sea level and organic carbon burial in the Early Jurassic.

Trends in relative sea-level change, shown by curves drawn from drill core and outcrop sections in Llandoverian carbonates of the Hudson Bay Platform, were used to correlate individual parasequences among widely separated localities. Two sequences, bounded by regional disconformities, include: (1) the Severn River Formation, and (2) the Ekwan River, Attawapiskat, and Kenogami River Formations. Initial onlap of marine facies at the base of the Severn River Formation progressed from north to south, occurring first in the Hudson Bay Basin, then in the Moose River Basin; final retreat of the seas at the end of Attawapiskat time was in the opposite direction. The most extensive inundations occurred during Ekwan River and Attawapiskat depositional times. Large-scale trends in the curves delineate four major Early Silurian sea-level highstands also recognized in other basins.<br>Reefs in outcrops along the Attawapiskat River represent one interval of reef growth, had a syndepositional relief of 8-10 meters, and were terminated by a relative sea-level fall. Their present distribution is controlled by variously uplifted fault blocks.<br>The most important diagenetic processes were early marine cementation and shallow burial diagenesis, and in the southwestern Moose River Basin early secondary dolomitization.

Full textAbstract:
A sequence stratigraphic study was conducted on the Mendi and Darai Limestone Megasequences in the foreland area of the Papuan Basin in Papuan New Guinea. It involved the integrated use of seismic, wireline log, well core and cuttings, strontium isotope age and biostratigraphic data. This study enhanced the understanding of the structure, stratigraphy and depositional architecture of the limestones, and the morphology of the basin at the time of deposition. The results of the study were integrated with published geological and tectonic models for the Papuan Basin to develop a consistent and coherent model for the depositional history of the limestones. Eleven third-order sequences were delineated within the Mendi and Darai Limestone Megasequences. Eight depositional facies were interpreted across these sequences, namely deep-shelf, shallow-shelf, backreef, reef, shoal, forereef, basin margin and submarine fan facies. Each facies was differentiated according to seismic character and geometry, well core and cuttings descriptions, and its position in the depositional framework of the sequence. Deposition of the Mendi Limestone Megasequence commenced in the Eocene in response to thermal subsidence and eustatic sea-level rise. Sedimentation comprised open-marine, shallow-water, shelfal carbonates. During the middle of the Oligocene, the carbonate shelf was exposed and eroded in response to the collision of the Australian and Pacific Plates, or a major global eustatic sea-level fall. Sedimentation recommenced in the Late Oligocene, however, in response to renewed extensional faulting and subsidence associated with back-arc extension. This marked the onset of deposition of the Darai Limestone Megasequence in the study area. The KFZ, OFZ and Darai Fault were reactivated during this time, resulting in the oblique opening of the Omati Trough. Sedimentation was initially restricted to the Omati Trough and comprised deep and shallow-marine shelfal carbonates. By the Early Miocene, however, movement on the faults had ceased and an extensive carbonate platform had developed across the Gulf of Papua. Carbonate reef growth commenced along topographic highs associated with the KFZ, and led to the establishment of a rimmed carbonate shelf margin. Shallow to locally deeper-marine, shelfal carbonates were deposited on this shelf, and forereef, submarine fan and basin margin carbonates were deposited basinward of the shelf margin. The Uramu High and parts of the Pasca High became submerged during this time and provided sites for pinnacle reef development. During the middle of the Early Miocene, a major global eustatic sea-level fall or flexure of the Papuan Basin associated with Early Miocene ophiolite obduction subaerially exposed the carbonate shelf. This resulted in submarine erosion of the forereef and basin margin sediments. Towards the end of the Early Miocene, however, sedimentation recommenced. Shallow-marine, undifferentiated wackestones and packstones were deposited on the shelf; forereef, submarine fan and basin margin sediments were deposited basinward of the shelf margin; and reef growth recommenced along the shelf margin and on the Pasca and Uramu Highs. By the end of the Early Miocene, however, the pinnacle reef on the Pasca High had drowned. During the middle of the Middle Miocene, subtle inversion associated with ophiolite obduction subaerially exposed the carbonate shelf, and resulted in submarine erosion of the forereef and basin margin sediments. Sedimentation recommenced towards the end of the Middle Miocene, however, in response to eustatic sea-level rise and flexure of the crust associated with foreland basin development. Shallow marine, undifferentiated wackestones, packstones and grainstones were deposited on the shelf; carbonate shoals were deposited along the shelf margin; and forereef, submarine fan and basin margin carbonates were deposited basinward of the shelf margin. Carbonate production rapidly outpaced accommodation space on the shelf during this time, resulting in highstand shedding and the development of a large prograding submarine fan complex basinward of the shelf margin. By the Late Miocene, carbonate deposition had ceased across the majority of the study area in response to a major global eustatic sea-level fall or inversion associated with terrain accreation events along the northern Papuan margin. Minor carbonate deposition continued on parts of the Uramu High, however, until the middle of the Late Miocene. During the latest Miocene, clastic sediments prograded across the carbonate shelf, infilling parts of the foreland basin. Plio-Pleistocene compression resulted in inversion and erosion of the sedimentary package in the northwestern part of the study area. In the southeastern part of the Papuan Basin, however, clastic sedimentation continued to the present day.

Full textAbstract:
Southern Alabama holds one of the world's most complete shallow shelf Cretaceous-Tertiary boundary sections. The boundary is exposed in a sequence of marl-limestone interbeds in a roadcut south-east of Braggs in Lowndes County, Alabama. Benthic foraminifera were extracted in 10cm intervals to obtain a high-resolution record of assemblage succession across this controversial boundary. A local sea level curve was then formulated using previous paleobathymetric foraminiferal assemblage models from the Gulf Coast and the Atlantic Coastal margin. Sea-level fluctuations thus evident have revealed a fourth-order cycle similar to those found by Briskin and Fluegeman (1990) with an average period of around 430 kyr through the Paleocene. This cycle includes a drop from outer slope to middle shelf conditions in the latest Cretaceous and a subsequent increase from inner shelf to outer shelf conditions in the earliest Paleocene. Within this cycle are several fifth-order cycles that are interpreted as having a periodicity of roughly 100 kyr. Sea-level cycles with Milankovitch frequencies occurring on an ice-free Paleocene Earth lend support to the concept of astronomical forcing of climate and thus sea-level.<br>Department of Geology

Full textAbstract:
The facies evolution of the Cretaceous/Tertiary sequence of NW Santander is considered in relation to the Cretaceous rifting and drifting, and Tertiary partial closure of the Bay of Biscay. Overlying the Palaeozoic basement are the fluvial Lower Triassic Buntersandstone and Upper Triassic Keuper evaporitic mudstone, deposited in a failed rift, extensional basin. Overlying Lower Jurassic carbonates are the syn-rift, continental elastics of the Vealden deposited in halfgrabens cut by transfer faults. The Vealden consists of two formations:- the lower, arenaceous-rich Barcena Mayor Fm. (braided stream environment) and the upper, argillaceous-rich Vega de Pas Fm. (meandering river). Overlying it is the Aptian Umbrera Fm. (calcarenite sheet), the Patrocinio Fm. (shoaling-up ward sandstone/marl alternation), the San Esteban Fm. (requienid/foraminiferal biomicrite of the internal platform) and the marls of the Rodezas Fm. The Upper Aptian Reocin Fm. is a requienid/foraminiferal biomicrite with thinned calcarenites deposited over active, diapiric palaeohighs. After initial marine and then equant calcite (meteoric phreatic) cementation, invasion of meteoric-derived groundwater over palaeohighs generated lenses of sucrosic dolomite in the Reocin Fm. Local mixing of further groundwater and Keuper-derived, sulphate-rich waters in karstic caverns precipitated sparry, baroque dolomite and Pb/Zn sulphides (by bacterial sulphate reduction). The clastic Lower Albian is a transgressive fluvial/estuarine/inner shelf sequence with tidal estuarine channels and sandwaves. The Middle/Upper Albian (syn-drift) has basal calcarenitic tidal sandwaves and is followed by storm/wave-reworked carbonates deposited on a homoclinal ramp. The clastic Lower Cenomanian is an estuarine/inner shelf deposit with tidal sandwaves and sandbars. The Middle/Upper Cenomanian is a storm/tide-dominated calcarenite. Outer shelf marls occur in the Turonian to Middle Campanian and the Upper Campanian to Middle Eocene is a sandy, foraminiferal inner shelf limestone. The Upper Eocene/Oligocene (syn-compression) is a carbonate slope-apron-reefal flysch deposit. It includes hemipelagic marl, neritic-derived calcarenitic turbidites and rudaceous mass flow deposits with highly polymict conglomerates. These were deposited coevally with Keuper piercement and thrust reactivation and date the Pyrenean compressional deformation here.

Full textAbstract:
This work focuses on the Late Pleistocene-Holocene transition in the southern Po Basin. Five areas were investigated, with the aim of unraveling the role of different allogenic factors (climate, eustacy, sediment supply) on stratigraphic architecture in the last 45 ky. The study starts from the distal portion of the basin (the coastal plain deposits) and then moves towards increasingly internal areas: the alluvial sector characterized by the Po channel belt deposits, and the mud-prone interfluvial succession between the Apenninic margin and the Po channel belt. In the coastal sector, high-resolution facies analysis, along with a well-constrained chronostratigraphic framework, led to the accurate paleoenvironmental reconstruction of the last 45 ky BP depositional history along the 93 km-long transect. It is also provided a sequence stratigraphic interpretation for the whole sedimentary succession. In the Po channel belt sector, based on 28 radiocarbon dates, facies interpretation from high-quality core descriptions and freshly-drilled continuous cores, the contrasting stratigraphic architecture of Late Pleistocene and Holocene deposits was highlighted. Changes in lithofacies and channel stacking patterns reveal the vertical superposition of amalgamated fluvial-channel sands (Late Pleistocene) and mud-dominated deposits (Holocene), with isolated fluvial-channel bodies. We also attempted to establish the link between facies architecture, sea-level fluctuations and climate changes. The 3rd study area (interfuvial succession) was selected to test a new method for paleosol identification, on the basis of geotechnical properties generated from pocket penetrometer values.
Through the reconstruction of the Biferno coastal deposits (4th study area, located ca. 300 km south of the Po Plain) we had the opportunity to document two coeval (Late Pleistocene - Holocene) coastal sedimentary successions, diverging in terms of shelf gradient and proximity to the LGM-lowstand Po Delta. The 5th study area, broadly coincides with Ferrara, was selected to show how high-resolution stratigraphic studies can be used for aquifer protection.

Full textAbstract:
<p> Late Jurassic through Early Cretaceous strata of the Gannett Group record initial development of the Sevier thrust belt and adjacent foreland basin. Concepts of nonmarine sequence stratigraphy were used to determine the depositional and base level history of the Gannett Group in southeastern Idaho and western Wyoming. Base level fluctuations were driven entirely by tectonic processes, while tectonic uplift in the source area was a major control on sequence development. Six measured sections were revisited or measured and correlated using the concepts of sequence stratigraphy. Four distinct sequences were identified and correlated. Each sequence can be divided into degradational, transitional, or aggradational systems tracts. Where the degradational systems tracts are preserved, they are represented by thin conglomerates. Transitional systems tracts overly the degradational systems tracts and consist of thick sections of laterally discontinuous sandstone and fluvial overbank muds, which grade laterally into continuous limestone and calcareous mudstones that comprise the aggradational systems tract.</p>

Full textAbstract:
The aims of this thesis are to evaluate whether the distribution of diagenetic features in nearshore successions can be explained within a sequence stratigraphic concept; to assess whether the identification and analysis of these features can be used to aid in making sequence stratigraphic interpretations; and to evaluate whether sequence stratigraphy can be used to predict the distribution of diagenetic heterogeneities at the field and inter-well scale. High resolution sequence stratigraphic frameworks have been established for two nearshore mixed carbonate/siliciclastic successions, using facies and early diagenetic analyses. These are the Upper Jurassic Corallian Group of south Dorset and the Lower Cretaceous lower to middle Ericeira Group of west central Portugal. Early diagenetic analyses (including petrographic, CL, XRD and stable isotope work), was performed on 143 samples extracted from concretions and cemented beds at key horizons within these two successions. The early diagenetic results from within the majority of these cemented bodies generally supports the proposed facies-based sequence stratigraphic interpretation of parasequences, systems tracts and sequences. At a parasequence scale, early diagenetic analyses indicate that concretionary growth is controlled by an initial phase of rapid burial, equating to the period of parasequence progradation, followed by a period of prolonged residence time within a single diagenetic zone. This equates to a period of non-deposition/marine flooding at a parasequence boundary. The results also indicate that the application of sequence stratigraphic theory can be used to predict the presence and location of early diagenetic concretions within similar successions. Analysis of early diagenetic features within carbonate cemented beds (such as marine hard-ground surfaces) also supports the facies-based identification of parasequences. Such features are closely associated with parasequence boundary formation and the available data indicates that it is possible to predict their distribution within systems tracts of similar successions. At t?e systems tract scale, analysis of upward increasing or decreasing trends in the volume of pore-mling authigenic phases relates to subtle changes in the rate of sedimentation versus the rate of accommodation creation. A general upward increase in the volume of early diagenetic products (particularly dolomite) is seen to Occur within highstand systems tracts, which is attributed to an increase in residence time within early diagenetic zones as the rate of progradation/burial increases and the rate of non-deposition/marine flooding at parasquence boundaries remains constant. Similarly, an upward increase in the a180 isotope values of carbonate cements (to a more marine value) occurs within shelf-margin or lowstand systems tracts where rates of ~e1ative sea-level are rising increasingly quickly and, a dominance of marine cements occurs within coarser gramed beds of transgressive systems tracts. At the sequence scale, early diagenesis is controlled by the degree of relative sea-level fall and subsequent subaerial exposure at the end of the highstand systems tract. If a sequence is bounded above by a type-t sequence boundary and there is evidence of a period of sub-aerial exposure then the effects of surface related diagenesis (dissolution, replacement and further cementation) can be identified. However. if a sequence is bounded above by a type-2 sequence boundary, the effects of any meteoric diagenesis are likely to be confined to in-extensive fresh-water lenses originating from an up-dip/sub-aerially exposed area of the basin. Consequently, primary early diagenetic cements contained within pore spaces of the existing systems tracts will be preserved. The approach taken in this research has demonstrated that early diagenesis is a useful tool in refining high resolution sequence stratigraphic interpretations and in the prediction of the distribution of early diagenetic heterogeneities within reservoir units. It also shows that for nearshore successions the distribution of diagenetic heterogeneities can be predicted at a range of scales.

The Artinskian to Kungurian Sequence of the Otto Fiord area is dominated by the Great Bear Cape, Raanes and Trappers Cove formations in addition to the upper portions of the Nansen and Hare Fiord formations. The Great Bear Cape Formation (10-300 m), in the Otto Fiord area, is a yellowish-weathering, cliff-forming, packstone to grainstone dominated by echinoderms, bryozoans, and brachiopods. The Raanes Formation (10-225 m) is greenish-weathering, recessive to resistant, shaly to silty, variably cherty wackestone to packstone dominated by bryozoans, brachiopods, crinoids, and sponge spicules in addition to resistant, massive, very fine-grained, bryozoan-lime mud wackestone forming bioherms. The Trappers Cove Formation (55-1000 m) is black to dark gray spiculitic chert that is interfingered with thinly-bedded, black, recessive shales and siltstones. (Abstract shortened by UMI.)

Full textAbstract:
Within Big Bend National Park, the unconformable contact between the Buda Limestone and the overlying Boquillas Formation represents the Commanchean-Gulfian boundary. Previous studies of the geochronology of this interval have relied primarily on provincial ammonite faunas rather than foraminifera, and place the Buda and basal Boquillas in the Lower Cenomanian. Because of its indurated nature, a comprehensive foraminiferal biozonation has not been acquired for the Buda Limestone. Recent revisions to Cretaceous foraminiferal biozonations and taxonomies necessitates a new biostratigraphic study of the Buda - Boquillas interval. The overlapping ranges of F. washitensis, G. bentonensis, G. caseyi, P. appenninica, P. delrioensis, P. stephani, and R. montsalvensis place the Buda within the upper portion of the Early to Middle Cenomanian Th. globotruncanoides Zone. Microkarst found on the surface of the Buda Limestone has been interpreted as representing a subaerial exposure and sequence boundary. However, microkarst-like features can result from subaqueous or intrastratal processes. Carbon and oxygen stable isotope analysis of the lower and middle Buda has indicated a mean δ13C value of 1.73‰ VPDB, which is in line with other values reported from the Lower Cenomanian. The top 2.6m of Buda contains a 0.62‰ negative δ13C shift from 1.88‰ VPDB to 1.26‰ VDPB in a 40 cm interval, expected if subaerial exposure occurred. Higher variation in measured carbon isotope values beneath the contact also lend evidence for meteoric alteration. The standard deviation in δ13C values from the top 2.8 m of the Buda is 0.207, which is 2.16 times larger than the rest of the studied section at 0.096. The Buda contains a shallow pelagic-dominated fauna of heterohelicids (45-90%), globigerinellids (3-37%), and hedbergellids (4-22%). Intermediate-depth globigerinellids display an initial increase followed by a marked decrease in abundance upsection, interpreted as sea level transgression and regression, respectively. The lower contact of the Buda with the Del Rio Clay has been previously interpreted as a subaerial exposure, and a P:B break from ~0% planktonics in the upper Del Rio to ~80% in the Buda supports this claim. This study therefore interprets both the upper and lower contacts of the Buda as
sequence boundaries. The overlying 1.2 m Boquillas is nearly devoid of benthics and represents a deeper assemblage including the double-keeled Dicarinella sp., as well as several Upper Cenomanian (D. algeriana Subzone) species. Based on foraminiferal data, the duration of the Buda - Boquillas unconformity is roughly equivalent to the missing Th. reicheli and Th. greenhornensis Biozones, or a sizable portion of the Middle Cenomanian.<br>Systematic paleontology -- Biostratigraphy of the Buda Limestone -- Biostratigraphy of the lowermost Boquillas Formation -- Stable isotope geochemistry.<br>Department of Geological Sciences

Full textAbstract:
The Monkton Formation of the western shelf stratigraphic sequence in Vermont (VT) is identified as a Lower Cambrian regressive sandstone unit containing parasequences recording tidal flat progradation. Previous workers identified cycles believed to represent parasequences in a portion of a 1034' deep geothermal well drilled at Champlain College in Burlington, Vermont. For this study, both outcrop and well geophysical surveys were completed to better identify gamma emission curves and relative values for parasequences and select lithologies that are indicators of bathymetry and sea level. After using physical stratigraphic techniques to assemble a composite stratigraphic section for the Monkton Formation, analysis of the gamma emission curve and relative gamma values resulted in the identification and characterization of parasequences and select lithologies within the Monkton. Interpretation of bathymetry-sensitive lithologies along with parasequence architecture and thickness trends reveals three distinctive intervals over the thickness of the Monkton. It is recognized that the succession of these intervals represents an overall decreasing rate in accommodation space generation through Monkton deposition.
Previous workers have suggested that biostratigraphic relationships of the Monkton Formation to the Potsdam Group in New York (NY) suggest that that they would be at least partially correlative. To further refine age relationships and constrain and compare the provenance of the Vermont stratigraphy locally and regionally, zircon samples were collected from the Monkton and the overlying Danby Formations and radiometric age determinations were completed by laser ablation–inductively coupled plasma mass spectrometry (LA-ICPMS) at University of Arizona Laserchron Center. Zircon age probability distribution curves show two dominate age peaks between 1.05-1.09 Ga and 1.15-1.18 Ga for the Monkton and Danby suggesting either a continuity of provenance through the Cambrian or the cycling of the Monkton's sand. The 1.05-1.09 Ga age range corresponds to rocks generated during the Ottawan Orogeny while the 1.15-1.18 Ga range is associated with the Shawinigan Orogeny and anorthosite-mangerite-charnockite-granite (AMCG) plutonism. Dominant age peaks in the Vermont samples between 1.15-1.18 Ga are similar to the 1.16 Ga age peak reported by other workers from the Altona and Ausable Formations of the Potsdam Group of New York. The shared dominant age peak and close proximity of the Vermont and New York stratigraphy may suggest a primarily shared provenance.

Master of Science<br>Geology<br>Matthew W. Totten<br>The Mississippian-aged St. Louis Limestone of Western Kansas is a carbonate resource play that has been producing oil, gas, and natural gas liquids (NGL) for over 50 years. The Mississippian Limestone is made up of heterogeneous limestones with interbedded layers of porous and non-porous units, abrupt facies changes, and diagenetic alterations. These factors combine to characterize the St. Louis Limestone's internal complexity, which complicates hydrocarbon exploration. This study focuses on improving the understanding of the geometry, distribution, and continuity of depositional facies within Kearny County, Kansas. Petrophysical analysis of a suite of geophysical logs integrated with core provided the basis for establishing facies successions, determining vertical stacking patterns within a sequence stratigraphic framework, and correlating areas of high porosity with a respective facies. The following depositional facies were identified; 1) porous ooid grainstone, 2) highly-cemented ooid grainstone, 3) quartz-carbonate grainstone, 4) peloidal grainstone, 5) micritic mudstone, and the 6) skeletal wackestone/packstone. The porous ooid grainstone is the chief reservoir facies, with log-derived porosity measurements between four and eighteen percent. In areas without available core, depositional facies were predicted and modeled using a neural network analysis tool (Kipling2.xla). Values derived from the evaluated core intervals and their respective geophysical logs served as the framework for the neural network model. This study illustrates the advantages of correlating depositional facies with reservoir quality and correlating those specific facies to geophysical logs, ultimately to create a greater understanding of the reservoir quality and potential within the St. Louis Limestone of western Kansas.

Full textAbstract:
The lower Cretaceous (Aptian to Albian) CLearwater Formation at Cold Lake, Alberta contains a complex assemblage of silicicastic strata. On the basis of detailed core analyses, Clearwater Formation strata have been subdivided into eight lithofacies and six recurring, facies associations. These facies associations are: (1) Tidal bar, (2) Sand flat, (3) Tidal-fluvial channel, (4) Fluvial channel, (5) Shoreface to foreshore, and (6) Offshore. Correlation of the facies associations and their bounding time-significant surfaces has led to the interpretation that Clearwater Formation strata are marine and tidally-influenced coastal embayment deposits that comprise four unconformity-bounded depositional sequences (1 to 4). Each sequence is made up of one or more incised valley-fill deposits within a backstepping parasequence set, indicating deposition in the transgressive system tract. The incised valley-fill deposits of each sequence, however, are interpreted a basinward shift of deltaic facies within a larger-scale marine transgression. Together, the four depositional sequences of the Clearwater Formation therefore compose a progradational sequence set. The Clearwater Formation is the primary reservoir unit at the Cold Lake heavy oil sands area with reserves estimated at $11,050\times 10\sp6$ m$\sp3$ of heavy crude bitumen. The distribution of hydrocarbons is related primarily to the distribution of reservoir quality strata and positive structure. Strata of facies associations 2 (sand flat) and 4 (fluvial channel) are observed to have the best reservoir quality. In the study area these strata occur in each of the upper three depositional sequences but are most abundant in sequences 3 and 4. The spatial distribution of reservoir-quality strata in Sequence 2 is such that additional hydrocarbon deposits are inferred to exist south of the study area, along the axis of the incised valley trend. Furthermore, northwest of the study are, Sequence 4 probably contains additional reservoir-quality strata along the trend of its incised valleys.

Full textAbstract:
This study investigates the depositional history of the Late Eocene sedimentary record in the northwest of the Thrace Basin in a sequence stratigraphic approach and estimates the contribution of regional tectonics, basin physiography and eustasy. Late Eocene sedimentary succession was analyzed in two third-order sequences based on two major data sets<br>seismic reflection and well data sets. Depositional Sequence-1, represented by progradational stacking patterns, comprises the coarse-grained Hamitabat turbidite system. The base of the Sequence-1 was defined as the base of channel fill deposits in the northern shelf setting and the base of slope fan deposits in the slope setting. This boundary separates Lower-Middle and Upper Eocene sediments. In the slope setting, the Hamitabat turbidite system was analyzed in three major depocenters<br>Western, Northwestern and Northeastern depocenters respectively.
Hamitabat turbidite system was controlled by the interaction of regional tectonics, basin physiography and eustatic fluctuations in the Late Eocene. This study highlighted the role of the regional variables<br>tectonic
influence and basin morphology on the submarine canyon formation. The facies distribution was controlled by the high subsidence rate of sea-floor dominantly instead of eustasy.
Depositional Sequence-2, represented by mostly retrogradational stacking patterns, is a clastic-carbonate mixed system. Depositional Sequence-2 was subdivided into three higher-order sequences. The lower sequence boundaries were induced by the rapid relative sea-level rise. The
upper boundary of the Depositional Sequence-2 was defined as the termination of clastic-carbonate mixed system and a candidate for the Eocene-Oligocene contact.

<p> Three studies on Cordilleran foreland basin deposits in the western U.S.A. constitute this dissertation. These studies differ in scale, time and discipline.

The maximum depositional ages using DZ U-Pb match existing biostratigraphic age controls. AFT is an effective thermochronometer for Lower to Upper Cretaceous foreland stratigraphy and indicates that source material was exhumed from >4–5 km depth in the Cordilleran orogenic belt between 118 and 66 Ma, and zircon (U-Th)/He suggests that it was exhumed from <8–9 km depth. Apatite U-Pb analyses indicate that volcanic contamination is a significant issue, without which, one cannot exclude the possibility that the youngest detrital AFT population is contaminated with significant amounts of volcanogenic apatite and does not represent source exhumation. AFT lag times are <5 Myr with relatively steady-state to slightly increasing exhumation rates. Lag time measurements indicate exhumation rates of ~0.9->>1 km/Myr.</p>

It overlies calcareous and fossiliferous strata of the Ostracode Limestone and is unconformably overlain by feldspathic and lithic-rich fluvial sandstone of the undifferentiated Upper Mannville. In the study area, Glauconitic Sandstone strata comprise three facies associations consisting of prograding shoreface to shallow shelf (FA1I), upper estuary channel fill (FA2) and tidally-influenced abandoned channel fill/interchannel (FA3) deposits.
The Jenner Upper Mannville E Pool is a 10 km long by 2 km wide north-south trending conventional oil pool located in Townships 19--20, Range 9W4 in southeastern Alberta. Since its discovery in 1963, the pool has produced 7.3 million barrels of 21.1° API oil and 6.7 billion cubic feet of gas from the Glauconitic Sandstone. The original oil in place is 28.6 mmbbl and estimated remaining reserves are of the order of 700 mbbl.

Full textAbstract:
Facies and stratigraphic architecture right at the transition from marine to non-marine environments is poorly documented. In the Cretaceous outcrops of Utah, Star Point and Blackhawk Formations are well studied. The nature of spatio-temporal transition of these two Formations, in the deposition-strike orientation, remains undocumented. This study characterizes facies and stratigraphic complexity at the transition of the two Formations that crop out in depositional-strike orientation in the Wasatch Plateau. Data from outcrop including photomosiacs and measured sections demonstrate this complexity at a range of scales. The Star Point constitutes a shoreface environment. The Blackhawk constitutes a coastal-fluvial environment.
In the northern part of study area, the transition from marine to continental strata is expressed by intertonguing succession. The dip-oriented outcrops show pinch-outs of two parasequences into coastal-plain deposits. This complexity decreases southward, the southern outcrops show a simple transition. At least two sequence boundaries are correlated across the outcrop belt.

Full textAbstract:
Meren field, located offshore Niger Delta, is one of the most prolific oil-producing fields in the Niger Delta. The upper Miocene D-07, D-08 and E-01 oil sands comprise a series of stacked hydrocarbon reservoirs in Block 2 of Meren field. These reservoir sandstones were deposited in offshore to upper shoreface environments.
Seven depositional facies were identified in the studied interval, each with distinct lithology, sedimentary structures, trace fossils, and wire-line log character. The dominant lithofacies are (1) locally calcite-cemented highly-bioturbated, fine-grained sandstones, (middle to lower shoreface facies); (2) cross-bedded, fine- to medium-grained well-sorted sandstones (upper shoreface facies); (3) horizontal to sub-horizontal laminated, very-fine- to fine-grained sandstone (delta front facies); (4) massive very-fine- to fine-grained poorly-sorted sandstone (delta front facies); (5) muddy silt- to fine-grained wavy-bedded sandstone (lower shoreface facies); (6) very-fine- to fine-grained sandy mudstone (lower shoreface facies); and (7) massive, silty shales (offshore marine facies).
Lithofacies have distinct mean petrophysical properties, although there is overlap in the range of values. The highest quality reservoir deposits are cross-bedded sands that were deposited in high-energy upper shoreface environments. Calcite cements in lower shoreface facies significantly reduce porosity and permeability. Integration of core and wire-line log data allowed porosity and permeability to be empirically determined from bulk density. The derived equation indicated that bulk density values could predict 80% of the variance in core porosity and permeability values.
Three parasequence sets were interpreted, including one lower progradational and two upper retrogradational parasequence sets. The progradational parasequence set consists of upward-coarsening delta front to upper shoreface facies, whereas the upward-fining retrogradational parasequence sets are composed of middle to lower shoreface deposits overlain by offshore marine shales.
The limited amount of core data and the relatively small area of investigation place serious constraints on stratigraphic interpretations. Two possible sequence stratigraphic interpretations are presented. The first interpretation suggests the deposits comprise a highstand systems tract overlain by a transgressive systems tract. A lowstand systems tract is restricted to an incised valley fill at the southeastern end of the study area. The alternate interpretation suggests the deposits comprise a falling stage systems tract overlain by transgressive systems tract.

Full textAbstract:
Multidisciplinary analysis of 10 newly-designated sequence stratigraphic reference sections has led to the recognition of 14 candidate bounding surfaces in the Upper Callovian - Lower Valanginian of the Arabian Plate. The <I>spinosum </I>Subzone, upper Remane Zone-B and late Early Valanginian bounding surfaces define two megasequences, within which 3<sup>rd</sup> Order depositional sequences can be identified and locally correlated. Across the Arabian platform most 3<sup>rd</sup> Order sequences comprise transgressive-regressive couplets bounded by Type I disconformities. Lowstand deposits are confined to relatively minor lowstand wedges, incised valley-fills and secondary condensed sections. Platform aggradation:progradation ratios are in the order of 1:4, reflecting limited on-shelf accommodation and prolific highstand shedding. The interplay between 2<sup>nd</sup> and 3<sup>rd</sup> Order sealevel changes has had a profound impact on sequence architecture. 3<sup>rd</sup> Order sequences deposited during 2<sup>nd</sup> Order sealevel rise are characterised by enhanced transgressive systems tracts (TST), well-developed MFS's and starved highstand systems tracts (HST); the associated lowstand systems tracts (LST) are represented by cryptic non-karstified palaeoexposure surfaces across the interfluves, lowstand wedges along the flanks of intra-shelf depressions and secondary condensed sections along the former platform slope. In contrast, 3<sup>rd</sup> Order sequences deposited during 2<sup>nd</sup> Order sealevel fall have starved TST's, subdued MFS's and enhanced TST's; the associated LST's are represented by mature paleokarsts across the interfluves, and major incised valley-fills along the former shelf break. MFS's have been dated using ammonites, capionellids and calcareous dinocysts. These datums have been used to constrain the age of genetic sequences and their associated (benthic) biotas. This has resulted in revised stratigraphic ranges for several key taxa.

Full textAbstract:
An integrated micropaleontological, mineralogical and sequence stratigraphical investigation was carried out across the Cretaceous/Paleogene (K/P) boundary in the Haymana basin, Turkey. A 29.41 m thick boundary section consisting of limestones and marls was measured and 90 samples were analyzed. Biostratigraphic and chronostratigraphic works are based on the planktonic foraminifera. 64 planktonic species were identified and 5 biozones were established. The biozones are, in ascending order, Planoglobulina acervulinoides zone, Racemiguembelina fructicosa zone, Pseudoguembelina hariaensis zone for the Late Maastrichtian<br>Guembelitria cretacea (P0) zone and Parvulorugoglobigerina eugubina (P1a) zone for the Early Danian.
In order to detect the mineralogical changes across the boundary bulk and clay minerals were analyzed using X-ray diffractometry (XRD). Calcite, quartz,feldspar and the clay minerals composed of smectite (montmorillonite) and chlorite are the main components of the rocks. A decrease in calcite and an increase in the detrital minerals (quartz, feldspar) and the clay minerals were detected in the boundary beds.
In order to find out the depositional history of the area a detailed microfacies study was performed and 10 microfacies type were determined. The microfacies types defined correspond to slope to basin environment. Based on microfacies analyses, the sequence stratigraphic framework of the boundary beds was constructed. K/P boundary beds were recorded in the transition of transgressive systems tract to highstand systems tract, coinciding with a maximum flooding surface. These beds show a similar pattern with many other K/P boundary beds in different locations of the world indicating eustatic sealevel variations overprint the tectonic control in the basin.
