Abstract:

RÉSUMÉ Le squelette presque complet d'un phoque fossile a été découvert près de La Durantaye, Québec, dans des sédiments marins associés à la submersion de la mer de Goldthwait. Une identification préliminaire a révélé qu'il s'agit d'un phoque gris ou d'un phoque à capuchon. Le cadre stratigraphique de la région a été précisé. De la base au sommet les unités suivantes se succèdent: 1) des sables et graviers grossiers (5 m) ; 2) des rythmites de type distal (2 m) ; 3) un till rougeâtre argileux très compact (1 à 2 m) ; 4) des sables et graviers fins biens lités (2 m) ; 5) des rythmites de type proximal (2 m) ; 6) un diamicton glacio-marin à Balanus hameh (2 m) ; 7) une argile silteuse parfois très noire (où fut trouvé le phoque fossile) (3 m) ; 8) des silts sableux très fossilifères contenant parfois des blocs (5 m) ; 9) une argile grise massive (jusqu'à 50 m) ; 10) des sables et graviers littoraux (1 m) ; 11) des sédiments fluviatiles récents (1 m). Les rythmites préglaciaires et postglaciaires sont associées respectivement aux varves de Beaupré et aux sédiments varvés de la rivière Chaudière. L'extension vers l'est de la moraine de Breakeyville est également proposée. Enfin, les silts sableux marqueraient un abaissement du niveau marin caractérisé par une activité glacielle pendant l'épisode marin.

Abstract:

RÉSUMÉ La stratigraphie de l'île aux Coudres est représentée par trois coupes naturelles affleurant dans le secteur de la pointe de la Prairie, sur la côte nord-ouest de l'île. La découverte d'un horizon organique, à mi-hauteur des coupes, permet d'attribuer au Wisconsinien moyen une partie des unités stratigraphiques de l'île. La coupe composite comprend, de la base au sommet, sept unités: unité n° 1 : sédiments sablo-graveleux stratifiés, associés à une plaine d'épandage fluvioglaciaire; unité n° 2: série de rythmites glacio-lacustres, argilo-silteuses; unité n° 3: sables fluviatiles stratifiés passant graduellement à un faciès de sédiments lacustres ou de plaine alluviale; unité n°4: sédiments organiques phytogènes comprenant de la tourbe compactée et des morceaux de bois aplatis, datés entre 34 430 et 26 400 ans BP, associés à un épisode terrestre, caractérisé par une plaine alluviale boisée et tourbeuse à caractère boréal; unité n° 5: sables stratifiés avec des déformations glacio-tectoniques; unité n°6: till et sédiments de contact glaciaire, associés à l'avancée glaciaire de Gentilly; unité n° 7: sédiments littoraux d'eau peu profonde de la mer de Goldthwait. L'épisode marin post-glaciaire a donné au relief de l'île une grande partie de son aspect actuel depuis 9800 9400 ans BP, soit depuis le Goldthwaitien III. Une série de radiodatations 14C est publiée. Les informations suggérées par l'analyse pollinique et l'analyse des diatomées d'échantillons provenant des unités stratigraphiques nos 2 et 4 permettent de mieux préciser leurs paléoenvironnements. Les corrélations possibles avec des unités stratigraphiques du Quaternaire des basses terres du Saint-Laurent et de la région de Québec sont discutées.

Abstract:

Une cartographie des dépôts meubles de la Gaspésie a permis d’identifier des unités lithostratigraphiques dont les noms formels sont proposés. Il existe des preuves pour deux glaciations distinctes représentées par des tills séparés par des intervalles de sédiments glacio-lacustres. La dernière glaciation a subi une inversion du sens de l’écoulement glaciaire et a permis la mise en place d’un troisième till, auquel est associé un diamicton glacio-marin déposé lors du vêlage des glaciers dans l’estuaire du Saint-Laurent. Enfin un quatrième till est dû à l’activité de calottes glaciaires confinées aux hautes terres du centre de la Gaspésie et qui ont donné naissance à des glaciers de vallée. Ces tills, en commençant par les plus vieux, ont été nommés Tamagodi, Langis, Petite-Matane et Grand-Volume. Les sédiments glacio-lacustres sous-jacents à chacun des deux premiers tills ne contiennent pas ou très peu de matière organique et n’ont pas été datés.

Abstract:

ABSTRACT Drilling in the floor of the Bélanger sand pit (Ontario) near Pointe-Fortune, Québec, added 3 stratigraphic units to those already exposed in the pit: a lowermost till, and an intermediate organic-bearing (?) sand-clay unit overlain by a massive lacustrine clay. The subsurface units, comprising about 70% of the stratigraphy, complete the Quaternary sequence exposed in the pit face : an organic-bearing silty sand (>40 000 years BP) unit truncated by an unfos-siliferous sand unit and overlain by the uppermost till. The overall sequence forms a continuous 18 m column of Quaternary sediments. The Pointe-Fortune sequence shows some similarities with the Trois-Rivières Quaternary series which includes the Saint-Pierre sediments >75 000 years old. In addition to stratigraphie information the combination of direct (drilling) and indirect (geophysical) methods of investigation by providing a three-dimensional picture of the subsurface has proved helpful in interpreting the stratigraphy. The geotechnical properties of a massive overconsolidated clay have been determined to facilitate the planning of future subsurface investigation.

Abstract:

Résumé La rivière Yamaska est l’un des affluents du Saint-Laurent les plus contaminés par les activités agricoles. Cette problématique touche particulièrement le sous-bassin de la rivière Noire où les dépôts de surface du Quaternaire sont discontinus, de faible épaisseur et souvent perméables. L’objectif de cette étude est de déterminer la vulnérabilité de l’eau souterraine sur une partie du sous-bassin de la rivière Noire (100 km2). La méthodologie utilisée comprend la caractérisation de l’aquifère, l’analyse des concentrations en nitrates et des contenus en δ18O, l’étude de la vulnérabilité en utilisant l’approche AQUIPRO et la modélisation hydrogéologique. Les résultats montrent une dégradation significative et d’origine anthropique de l’eau souterraine : plusieurs concentrations excèdent 1 mg N-NO3/L et quelques-unes excèdent 10 mg N-NO3/L. Les puits contaminés sont situés sur les crêtes topographiques où le silt argileux est absent et le till discontinu, et où la plus grande vulnérabilité AQUIPRO a été identifiée. Une diminution des concentrations avec la profondeur de prélèvement s’explique par un écoulement souterrain peu profond entraînant les nitrates vers un ruisseau et vers la rivière Noire. La vulnérabilité de l’eau souterraine est ainsi beaucoup plus grande dans les couches superficielles du roc fracturé. Le temps moyen de séjour de l’eau souterraine est estimé à 20 ans. Les concentrations mesurées permettent d’établir un lien direct entre la vulnérabilité, les dépôts de surface, la stratigraphie du substrat et les directions de l’écoulement souterrain. Elles démontrent aussi la présence d’une contamination de l’eau souterraine par les nitrates qui est susceptible d’augmenter si aucune mesure préventive n’est mise en place.

Abstract:

Lacustrine and alluvial stratigraphic sequences in the southern Animas Valley of New Mexico allow reconstruction of late Quaternary climates. Four separate stands of late Quaternary Lake Cloverdale in the southern Animas Valley are recorded by lacustrine shoreline deposits. Soils and stratigraphic evidence show that three young lake highstands occurred during the Holocene and that a higher lake stand occurred 18,000 to 20,00014C yr B.P. Fluvial systems aggraded the southern Animas Valley during the middle to late Holocene. The late Quaternary stratigraphy shows that several periods during the late Holocene were characterized by higher effective precipitation than at any time since the last glacial maximum.

Abstract:

A conceptual discussion is presented concerning some important aspects of the modern sedimentary geology as they are related to particularities of the Quaternary sedimentary record. This study intends to provide new elements for a most objective analysis of Quaternary deposits. The approach utilized is based on the purpose to integrate stratigraphie and sedimentologic analysis. The allostratigraphic perspective and the faciologic analysis of events are hereby recommended. The association of geomorphology and stratigraphy is also emphasized as a basic aspect to studies of Quaternary deposits. Concerning this aspect, the identification of depositional surfaces is particularly important.

Abstract:

AbstractDetailed morpho- and lithostratigraphic investigations, allied with radiometric dating, in the Voidomatis basin, Epirus, northwest Greece, have identified four Quaternary terraced alluvial fills that range from middle Pleistocene to historic in age. Major-periods of alluviation during the late Quaternary were associated with valley glaciation (ca. 26,000–20,000 yr B.P.) and subsequent deglaciation (ca. 20,000–15,000 yr B.P.) in the Pindus Mountains during Late Würmian times, and more recently linked to overgrazing sometime before the 11th century AD. The late Quaternary alluvial stratigraphy of the Voidomatis River is more complex than the “Older Fill” and “Younger Fill” model outlined previously, and it is suggested that these terms should no longer form the basis for defining alluvial stratigraphic units in the Mediterranean Basin.

Abstract:

AbstractWe investigate the stratigraphy of Neogene and Quaternary intervals of the Schelphoek borehole (Schouwen, Zeeland, the Netherlands). The Breda Formation (Miocene-Zanclean) contains three sequences separated by hiatuses. The Oosterhout Formation (Zanclean-Piacenzian) contains at least two sequences. This formation is overlain by seven sequences of the Gelasian Maassluis Formation that almost certainly represent glacial cycles. The three lowermost sequences are provisionally assigned to the Praetiglian (MIS 96, MIS 98 and MIS 100). A large hiatus exists between the top of the Maassluis Formation and the base of the late Middle to Late Quaternary succession. Due to extensivein situreworking of older strata (including fossils) at the base of several of the formations, their exact boundaries are difficult to establish. The Neogene succession in the Schelphoek borehole is compared to the stratigraphic successions in the Antwerp area to the south and the Dutch coastal area and continental platform to the north. Finally, the stratigraphic context of the Gelasian (‘Tiglian’) mammal fauna dredged from the bottom of a major tidal channel in the adjacent Oosterschelde is assessed by comparison with the Schelphoek borehole.

Abstract:

ABSTRACT The Quaternary stratigraphy of the continental shelf offshore of South Carolina consists of stratigraphic units deposited in coastal-plain, shallow marine, and shelfal environments bounded by composite erosional surfaces that developed in response to numerous glacioeustatic cycles and were overprinted by regional uplift. These units are commonly distributed laterally, rather than stacked vertically, a function of the long-term low shelf gradient and the resulting lack of accommodation. Additionally, marine processes such as waves and geostrophic currents can rework both relict and modern sediments across the continental shelf. This study integrates high-resolution geological and geophysical datasets acquired offshore and onshore with existing data onshore into a comprehensive conceptual model describing the Quaternary geologic evolution of the coastal plain and continental shelf within a study area of approximately 8,000 km2. We use seismic facies and core analysis to define stratigraphic units associated with transgressive, regressive, and lowstand systems offshore. Regressive systems include progradational wave- and river-dominated deltaic and shoreface deposits. Lowstand systems consist of a complex network of paleo-incisions produced by regional, Piedmont-draining fluvial systems and smaller coastal plain rivers. Transgressive systems include paleochannel-fill successions dominated by mud-rich, tidally influenced backbarrier deposits, cuspate and linear shelf sand ridges, and transgressive sand sheets and shoals. The low-accommodation setting of the continental shelf influences the stratigraphic record in several ways: 1) the geometry of progradational coastal lithosomes, 2) the development of composite allogenic erosional surfaces, 3) the deposition of widespread, thin transgressive sand sheets, and 4) the restriction of thicker transgressive deposits to paleo-incisions. In this setting, the use of a bounding surface scheme that is hierarchical is preferable to the more common sequence stratigraphic or allostratigraphic convention for several reasons: 1) major erosional bounding surfaces are commonly amalgamated; 2) lower-order surfaces capture internal variability, which is key to the genetic interpretation of stratigraphic units, and 3) stratal stacking patterns typically used to define a sequence stratigraphic framework are rare.

Abstract:

In the coming years, the Anthropocene Working Group (AWG) will submit its proposal on the ‘Anthropocene’ to the Subcommission of Quaternary Stratigraphy (SQS) and the International Commission on Stratigraphy (ICS) for approval. If approved, the proposal will be sent to the Executive Committee of the International Union of Geological Sciences (IUGS) for ratification. If the proposal is approved and ratified, then the ‘Anthropocene’ will be formalized. Currently, the ‘Anthropocene’ is a broadly used term and concept in a wide range of scientific and non-scientific situations, and, for many, the official acceptance of this term is only a matter of time. However, the AWG proposal, in its present state, seems to not fully meet the requirements for a new chronostratigraphic unit. This essay asks what could happen if the current ‘Anthropocene’ proposal is not formalized by the ICS/IUGS. The possible stratigraphic alternatives are evaluated on the basis of the more recent literature and the personal opinions of distinguished AWG, SQS, and ICS members. The eventual impact on environmental sciences and on non-scientific sectors, where the ‘Anthropocene’ seems already firmly rooted and de facto accepted as a new geological epoch, are also discussed. This essay is intended as the editorial introduction to a Quaternary special issue on the topic.

Abstract:

AbstractExploration in a mature basin requires a detailed classification and standardisation of rock stratigraphy to adequately comprehend the depositional history and prospect architecture. The pre-Quaternary Stratigraphic Nomenclature of the Netherlands compiled by Van Adrichem Boogaert & Kouwe in 1993 provided a consistent framework for use by the Dutch geological community. Over the past twenty years, new biostratigraphic techniques and continued exploration in the Netherlands have provided additional stratigraphic information. Based on this information the Late Jurassic lithostratigraphy in particular, shows significant inaccuracies. The Callovian-Ryazanian strata from the northern offshore of the Netherlands' territorial waters, termed the Central Graben Subgroup and Scruff Group, reveal a complex sedimentary history. The combination of non-marine to shallow marine lateral facies changes, repetitive log and facies characteristics in time, sea-level and climate change, salt tectonics and structural compartmentalisation hamper straightforward seismic interpretation and log correlation. Recognition of three genetic sequences by Abbink et al. in 2006 enabled an improved reconstruction of the geological history. Further improvements in refinement and reliability of the stratigraphy together with new information on the facies and ages of the successions and about the subsequent tectonostratigraphic development of the northern Dutch offshore area form the basis of the present revision. As a result, earlier lithostratigraphic models have been changed and new lithostratigraphic relationships and names are introduced in this paper.

Abstract:

Corrections to the Quaternary stratigraphic division of Serbia was updated/renewed by lowering limit of the Pleistocene / Quaternary to the beginning of the Gelasian that is at approximately 2.588 million years. Rather than the officially rejected Penck & Br?ckner Alpine stratigraphic model, the use of oxygen isotope stages (OIS / MIS) is recommended. Climatostratigraphic terms glacial and interglacial have a regional applicability and their use is recommended only in areas where there are traces of glaciation, while the terms cold and warm stage (or moderate) stages should be used within the global context. Eopleistocene is a regional term for the former Soviet Union and due to its uniqueness it can hardly be applied in the stratigraphical scheme of the Quaternary depostis in Serbia. With the latest extension of the Lower Pleistocene, further use of Eopleistocene would lead to further confusion in stratigraphic correlation as such the use of the Lower / Early Pleistocene or other appropriate stratigraphic units is recommended.

Abstract:

In the study of Quaternary deposits of the Crimea selected two phases. In the first stage (since the late XIX century to the sixties of XX century) stratigraphic description of the Quaternary strata was based on the allocation of terraced complexes (a marine terraces - in the coastal part and synchronous them alluvial ones - in continental part of the Crimean peninsula). In the second stage description of the Quaternary deposits is made on the basis of their climatic and stratigraphic dissection under the leading role of the loess-soil formation structure. The basis for stratigraphic subdivision of Quaternary deposits of the Crimea was the structure of the valleys of the paleo-Dnieper and paleo-Dniester. It is shown that the nonlinear, reversible character of Black sea level changes that took place in the Quaternary can be broken a rule “the lower the hypsometrically level of the terrace is, the younger this terrace is”.

Abstract:

AbstractThick and predictable deposits of fine grained Quaternary materials have been used for the siting of waste management facilities in Ontario. The search for such sites is founded on the application of techniques in Quaternary geology and hydrogeology. Two examples are presented. Oxford County is located southwest of Toronto in an area of parallel morainic ridges separated by flat till plains. Conventional wisdom would focus on the till plains for thick, consistent fine grained Quaternary Sediments. However, the careful analysis of the Quaternary stratigraphy and glacial history revealed that better sites are located along the moraines. A site on the Ingersoll Moraine was studied in detail and defended at a public hearing. Concerns about the geology of the materials were allayed by the confirmation of homogeneous clayey silt materials exposed when the site opened in late 1986. A much wider ranging search was undertaken for a major hazardous and liquid industrial waste treatment and disposal facility for the Province of Ontario. Progressively more detailed investigations of the Quaternary geology were used to assist a multi-disciplinary site selection team. Initial interpretations covered an area of 75 000 km2 at a scale of 1:250 000. Eight candidate sites were then selected for further investigation with five continuously sampled stratigraphic boreholes. The chosen site is located in a depression in the bedrock filled with 40 m of glaciolacustrine clayey silt. Site specific hydrogeological and geotechnical studies were integrated with a detailed geological investigation.

Abstract:

The first deployment of the P-Cable™ high-resolution 3D (HR3D) seismic acquisition system in the Gulf of Mexico has provided unprecedented resolution of depositional, architectural, and structural features related to relative sea-level change recorded in the Quaternary stratigraphy. These details are typically beyond conventional 3D seismic resolution and/or excluded from commercial surveys, which are generally optimized for deeper targets. Such HR3D data are valuable for detailed studies of reservoir analogs, sediment delivery systems, fluid-migration systems, and geotechnical hazard assessment (i.e., drilling and infrastructure). The HR3D survey ([Formula: see text]) collected on the inner shelf ([Formula: see text] water depth) offshore San Luis Pass, Texas, imaged the upper 500 m of stratigraphy using peak frequency of 150 Hz and [Formula: see text] bin size. These data provided an exceptionally well-imaged example of shallow subsurface depositional system and stratigraphic architecture development during a lowstand period. The system evolved from a meandering channel with isolated point-bar deposits to a transgressive estuary characterized by dendritic erosional features that were eventually flooded. In addition, HR3D data have identified a previously unidentified seismically discontinuous zone interpreted to be a gas chimney system emanating from a tested (drilled) nonproductive, three-way structure in the lower Miocene (1.5 km depth). Within the shallowest intervals ([Formula: see text]) and at the top of the chimney zone, seismic attribute analysis revealed several high-amplitude anomalies up to [Formula: see text]. The anomalies were interpreted as reaccumulated thermogenic gas, and their distribution conforms to the stratigraphy and structure of the Quaternary interval, in that they occupy local fault-bounded footwall highs within remnant coarser-grained interfluvial zones, which are overlain by finer grained, transgressive deposits.

Abstract:

Abstract. Magnetic dating includes all approaches dealing with the temporal variation of the Earth’s magnetic field (EMF) as well as with the application of climate dependent variations of rock magnetic properties of sedimentary sequences and their correlation to independently dated palaeoclimatic archives. Palaeomagnetism has an outstanding impact on geosciences in general and especially on Quaternary chronology and palaeoclimate research. Palaeomagnetic dating employs the temporal variation of the direction as well as the intensity of the EMF on time scales from 102 to 107 years. The well-known temporal pattern of reversals of the EMF on time scales from 104 to 107 years and the shorter secular variation (amplitude 10-30°, time scale 1 to 103 years) provide an excellent tool for stratigraphic subdivisions. Records of the intensity variations of the EMF as well as the indirect dating by means of correlating rock magnetic property variations from sedimentary archives to dated palaeoclimatic records also serve as dating tools. Field methods as well as laboratory methods and techniques in data analysis will not be discussed in this paper. It is our aim to give a short and subjective overview on palaeomagnetism and magnetic susceptibility stratigraphy as dating tools in Quaternary science.

Abstract:

AbstractPaleosols occur in the Driftless Area of southwestern Wisconsin because this area escaped direct Pleistocene glaciation, allowing long-term loess and colluvium accumulation in selected settings. The most complete known depositional sequence at Oil City, Wisconsin, contains eight lithologic units with five paleosols, all with normal remanent magnetism (i.e., <780 ka). Previous work characterized the stratigraphy, pedology, micromorphology, and clay mineralogy of the section. We investigate chemical weathering of the 8–63 µm silt fraction using X-ray diffraction (XRD) and elemental geochemistry by portable X-ray fluorescence (pXRF). Elemental ratios TiO2/CaO, Zr/Sr, and Rb/Sr generally align with the pedological evidence of weathering. Mineral ratios plagioclase/quartz and K-feldspar/quartz display greater scatter and less certainty in interpretation. The paleosols with Bt horizons have ratios indicating greater weathering than the modern soil. The most weathered paleosol is formed in the unnamed fourth loess unit stratigraphically below the Loveland Member. The stratigraphic position and higher degree of weathering support correlation of the fourth loess with the Yarmouth Geosol and Crowley’s Ridge Silt of the Middle Mississippi valley. Geochemical indices by pXRF are more consistent with established lithologic breaks than mineralogy by XRD. Our results support the use of pXRF for stratigraphic and weathering studies of Quaternary sediments.

Abstract:

Following the decision of the International Union of Geological Sciences on the transfer of the lower boundary of the Quaternary System/Period and the Pleistocene Series/Epoch from 1.8 Ma to 2.58 Ma (to the base of the Gelazian Stage/ Age of the Pliocene), the changes have been made in Stratigraphic charts of Neogene and Quaternary Deposits of Belarus (2010). The Neogene – Quaternary boundary in the territory of Belarus is aligned with the International Chronostratigraphic Chart and is made between the Kholmech horizon (analogue of Zanclean and Piacenzian, Pliocene) and the Dvorets horizon (analogue of Gelasian) displaced from the Pliocene to the lower base of the lowermost Pleistocene. Its new position in the sections is substantiated by paleobotanical data. New geological units were introduced into regional and local stratigraphic charts of the Neogene and Quaternary.
