Abstract:
In this paper, the seismic profiles of the central area of Huanghua depression were balanced and restored by 2DMove software. We calculated the extension parameters of the balanced corss-section in the different period, analyzed the tectonic deformation of Huanghua depression. According to the total extension parameters of balanced cross-section, the Cenozoic evolution of the Huanghua depression may be divided into two phase of tectonic evolution which are rifting stage and post-rift stage. The rifting stage included three episodic rifting: The third members of Shehejie with the rapidest subsidence,Ⅰepisodic rifting; The first and second members of Shahejie with the fault-depression,Ⅱepisodic rifting; The Dongying with terminal fault-depressed ,Ⅲepisodic rifting . The Huanghua depression shows a double-layer vertical structure with faulting structures in the lower and depressing structure in the upper sector.

Abstract:
The late Cretaceous to early Oligocene strata in the northern continental margin of the South China Sea (SCS) are significant for understanding the contemporaneous continental rifting of the margin prior to the opening of the central SCS oceanic basin. Using new seismic and drilling data, combined with previous results, we have identified three episodes of rifting from the late Cretaceous to early Oligocene based on analyses of major unconformities, tectonostratigraphic units, and sedimentary facies. The first episode of rifting that occurred only in the Pearl River Mouth (PRM) basin during the late Cretaceous to Paleocene is observed. During the early to middle Eocene, littoral-shallow lacustrine and fan-delta facies were distributed in some faulted half-grabens in the Qiongdongnan (QDN) basin, while deep lacustrine deposits widely developed in the PRM basin. During the late Eocene to early Oligocene, marine transgression propagated from the southeast into the QDN, southern PRM, and Taixinan basins. We have inferred that late Cretaceous to the middle Eocene rifting is characterized by uniform lithospheric stretching related to the retreat of the paleo-Pacific subduction zone, whereas the late Eocene to the early Oligocene rifting controlled by multiple factors is characterized by depth-dependent lithospheric extension. It is the differential rifting process that led to the differentiation in the types and distribution of source rocks in the basins of northern SCS margin.

Abstract:
North Uskyurt Basin, located on Turan Plain, northwestern Central Asian, is continental polycyclic cratonic. The structural evolution of the basin underwent six phases: basement formulation, passive edge, rifting, post-rifting, compression, early Neogene depression. Regional structural evolution takes control of complicated transition of North Uskyurt sedimentary structure. In general, basin sedimentary environment underwent basement (granite, metamorphic rocks) passive edge, late Devonian epoch carboniferous period (marine facies) rifting, late Permian epoch-triassic period (continental facies) post-rifting, Jurassic period-Cretaceous period (Marine-continental Transition Facies, marine facies) compression, late Eocene-Miocene epoch (marine-continental facies coexistence) Neogene depression, Pliocene-Holocene (continental facies). Consequently, sedimentary formation in which various sedimentary environment, such as marine facies, continental facies, are coexisted with various rock types, such as clastic rocks, carbonate rocks, is generated.

Abstract:
La Corse Alpine offre une section complète du prisme orogénique alpin où la plupart des équivalents des unités décrites dans les Alpes Occidentales peuvent être trouvés sur une section de 40 km. Les minéraux d'haute pression sont exceptionnellement bien préservés, particulièrement la lawsonite, offrant un accès unique à la compréhension de zones de subduction. La Corse alpine est formée par une pile complexe d’unités métamorphiques d'origine continentale et océanique. Ces unités ont été interprétées soit comme des mélanges tectoniques complexes formés pendant la subduction alpine, soit comme les parties plus continues de lithosphère continentale et-ou océanique. Les rares estimations de condition PT sur des larges régions de la chaîne résultent en plusieurs incertitudes dans l'identification des limites séparant les unités qui ont subi des évolutions tectono-métamorphiques différentes et, par conséquent, dans la définition d'une architecture complète de la chaîne. Les données de terrain, structurelles et métamorphiques obtenues dans cette étude aux différentes échelles suggèrent que la chaîne de la Corse alpine est caractérisée par une forte conservation de structures pré-alpin, de la micro-échelle à l'échelle de la chaîne, malgré la déformation intense associée avec le métamorphisme, qui a localement donné les conditions du facies éclogitique et lawsonite. En détail, seulement neuf domaines tectono-métamorphiques homogènes ont été identifiés. Ces terrains peuvent être attribué aux domaines paléogéographiques différents qui ont subi des évolutions tectono-métamorphiques différentes. Malgré ça, les données géochronologiques fournies pendant cette étude indiquent que la Corse alpine résulte d'une évolution complexe, étant caractérisée par la signature claire tant de la tectonique alpine Eocène, à 35 Ma, que de la tectonique apennine, à 25 Ma. Les résultats fournis dans cette thèse contribuent non seulement à la compréhension des processus de subduction et de formation de montagnes, mais donnent aussi des contraintes importantes pour déchiffrer les systèmes Tethys-Alpes et Alpes-Apennine
Alpine Corsica offers a complete section through the Alpine orogenic wedge where most equivalent of the units described in the Western Alps may be found over a 40 km section. High-pressure mineral assemblages are exceptionally well preserved, especially lawsonite, offering a unique access to the understanding of deeply subducted terranes.Alpine Corsica consists of a complex stack of variably metamorphosed units of continental and Tethys-derived material. These units have been interpreted either as complex tectonic mixing formed during the Alpine subduction, or as more continuous portions of continental and/or oceanic lithosphere. The lack of detailed PT estimates over wide regions of the belt results in several uncertainties in identifying the boundaries separating units that experienced different tectono-metamorphic evolutions and, consequently, in the definition of an exhaustive architecture of the belt.Field, structural and metamorphic data collected in this study at different scales suggest that the Alpine Corsica belt is characterized by a high preservation of pre-Alpine sctructures, from the micro-scale up the scale of the belt, despite the intense deformation essociated with metamorphism, which locally reached lawsonite-eclogite metamorphism. In particular, only nine homogeneous tectono-metamorphic domains have been identified. These terranes can be referred to different paleogeographic domains that experienced different tectono-metamorphic evolutions.Despite that, geochronological data provided during this study indicate that Alpine Corsica results fro a complex polyphase evolution, being characterized by clear signature of both Alpine tectonics, at around 35 Ma, and Apennine tectonics, at around 25 Ma.Results provided in this paper contribute not only to the understanding of processes of subduction and mountain building, but also give important constraints for deciphering the Tethys-Alps and Alps-Apennine systems

Abstract:
Les rifts continentaux sont des zones étroites et allongées d'extension de la lithosphère. Une étude du champ de déformation en surface montre leur carractère asymétrique quasi-systématique. Cette asymétrie est acquise tardivemen t au cours de la déformation. La lithosphère étant considérée comme un multicouche fragile/d uctile, une modélisation analogique de sa striction est réalisée en appliquant une extension ponctuelle sur des multicouches sable/silicone dimensionnés. Ces expériences montrent que: -l'asymétrie est due à la présence d'un cisaillement ductile à la ba se des rifts qui accommode un décalage entre les déformations de la croûte fra gile et du manteau supérieur -la déformation est contrôlée par la couche la plus résistante de la lithosphère (manteau supérieur) -la déformation du manteau supérieur est conditionnée par des hétérogénéités internes préexistantes (anciennes structures) -la largeur initiale des rifts est fonction de la profondeur de l'interface fragile/ductile dans la croûte ou dans le manteau -la largeur d'une zone active étirée dépend du couplage entre la coûte fragile et la croûte ductile. Ces conclusions sont appliquées au rift oligocène ouest européen et permettent d'expliquer la variation du champ de déformation d'un segment du rift à l'autre. ,

Abstract:
The history of uplift, volcanism and faulting, and past geophysical studies suggest that extension in the Kenya Rift is actively driven by an upwelling thermal anomaly. The KRISP 94 experiment included a 440 km seismic refraction profile in southern Kenya to investigate the deep structure of the rift, 150 km east of the exposed boundary between the Archean Nyanza craton and the Proterozoic Mozambique orogenic belt. Combined travel-time and gravity interpretations produce an integrated crustal and upper mantle model, showing extensive thrusting of the mobile-belt over the cratonic margin. The rift itself has developed above the buried suture between these units. The asymmetric rift basin (filled with low velocity lavas or sediments) has a maximum depth of 4 km adjacent to the western bounding fault. The high velocity (7.0-7.2 kms-1) lowest crustal layer is modified beneath the rift, possibly by the addition of cumulate layers (products of fractional crystallization). A small amount of crustal thinning (1-2 km) directly beneath the rift axis suggests a pure-shear mechanism at depth. Minimum crustal extension is 4 km, but could be up to 10 km if the whole of the lowest crustal layer is a new magmatic addition. A long-wavelength regional gravity trend is consistent with the presence of a mantle plume beneath the craton to the west. A study of local earthquakes in Tanzania shows that the rift is propagating southwards along the craton margin. Many deep earthquakes (> 20 km) suggest cooler crustal temperatures than in Kenya, and preliminary travel-time tomography shows only minor crustal velocity variations. The results are consistent with rifting in Kenya being driven by an upwelling diapir, originating from a mantle plume beneath the craton. As it has spread, the diapir has been focussed along the suture between the Archean and Proterozoic units, but has not yet produced extensive crustal modification of the youngest part of the rift in Tanzania.

Abstract:
Continental rifting, like other plate tectonic processes, plays a large role in shaping the Earth's crust. Active rift zones evolve from repeated tectonic and magmatic events including volcanic activity. Through investigations of currently and previously active rifts, scientists have discovered considerable interactions between these tectonic and magmatic processes during a rift's evolution; however questions remain about these interactions especially in youthful stages of rifts. We investigate an early phase magma-rich section of the East African Rift System (EARS), named the Eastern Branch to assess volcano-tectonic interactions. The Eastern Branch of the EARS consists of volcanically rich rifts that are actively spreading the Nubian Plate, Somalian plates, and Victoria block at different evolutionary stages making it an ideal study area for volcano-tectonic interactions. Our initial investigation of active volcano-tectonic interactions centered on a rifting event that occurred between 2007-2008 in the Natron Rift, a rift segment in the southern Eastern Branch located in Northern Tanzania. This rifting event contained multiple occurrences of tectonic, magmatic, and volcanic activity in close proximity. We examine the stress transferred from these events to the Natron Fault, which is the major border fault in the area, with analytical modeling using the USGS program Coulomb 3.4. We processed Global Positioning System (GPS) data that recorded slip on the major border fault in the region in early January 2008 and test which events could generate large enough stress changes to trigger the observed slip using a previously defined threshold of 0.1 MPa. These initial models were created using simplified model parameters, such as an elastic homogeneous half-space, and find that 1) magmatically induced stress perturbations have the potential to trigger fault slip on rift border faults, 2) magmatic events have the potential to trigger strike‐slip motions on a rift border fault, and 3) the proximity of magmatic activity may affect occurrences of slip on adjacent border faults. We then further investigate volcano-tectonic interactions in the Natron Rift by testing using numerical modeling with the CIG finite element code PyLith. We systematically test how adding topography, heterogeneous materials, and various reservoir volumes to a deflating 3 km deep magma reservoir system at the active volcano Ol Doinyo Lengai can affect stress transfer to the adjacent Natron Fault. We compare eight models with variations in topography, material properties, and reservoir volumes to calculate the percent differences between the models; to test their effects on the stress change results. We find that topography plays the largest role with the effect increasing with reservoir size. Finally, we seek to improve the capability of investigating volcano-tectonic interactions in the Natron Rift at faster time- scales by improving Global Navigation Satellite System (GNSS) positioning data (latitude, longitude, and height) collection and distribution capabilities. In the final part of this work, we describe a new Python-based data broker application, GNSS2CHORDS, that can stream real-time centimeter precision displacement data distributed by UNAVCO real-time GNSS data services to an online EarthCube cybertool called CHORDS. GNSS2CHORDS is applied to the TZVOLCANO GNSS network that monitors Ol Doinyo Lengai in the Natron Rift and its interactions with the adjacent rift border fault, the Natron Fault. This new tool provides a mechanism for assessing volcano-tectonic interactions in real-time. In summary, this work provides a new avenue for understanding volcano-tectonic interactions at unprecedented, 1-second time-scales, demonstrates slip can be triggered by small stress changes from magmatic events during early phase rifting, and provides insights into the key role of volcanic topography during volcano-tectonic interactions.
Doctor of Philosophy
Investigating interactions between active volcanoes and tectonics (fault zones) is important for understanding how continental rifts grow and evolve over time. Modern researchers use geodetic data, geologic models, and computer simulations of rift processes; like volcanic eruptions and fault movement; to understand how stress in transferred and material deforms due to rift activity. We are especially interested in understanding the stress interactions when volcanic eruptions and earthquakes happen together over a short time period. Our projects apply these tools to examine a segment of the largest active continental rift zone, the Natron Rift in the East African Rift System (EARS), to understand more about the details of these volcano-tectonic interactions when continents break apart (rifting). We first present results that stress transferred to the Natron Fault associated with magmatic activity from the volcano Ol Doinyo Lengai may trigger a major fault to move. Next, we continue our investigations into volcano-tectonic interactions by seeing how volcanic properties could affect stress transferred in the Natron Rift region. We choose to initially test stress variations associated with different 1) topography surfaces, 2) material properties, and 3) reservoir volumes associated with the volcano Ol Doinyo Lengai using a more advanced computer modeling approach. This deeper investigation provides information about the individual roles these parameters play in a younger rift region. We present results that topography has the most influence on the stress transferred to the Natron Fault in our models, and that the other parameters did not play a large role in influencing the stress transferred. Finally we work to increase the ability for researchers to perform geodetic studies in the Natron Rift by providing a new method to share surface displacement data at an unprecedented 1 position a second rate (near real-time). This new method is a data broker application called GNSS2CHORDS that can stream cm precision displacement data to an online cybertool called CHORDS. With our models and data provided through open source methods this work contributes significantly to our understanding of volcano-tectonic interactions.

Abstract:
This thesis is focused in the processes that took place in the Tyrrhenian Sea, which is a Neogene basin belonging to the Western Mediterranean realm. Its formation is related with the subduction system of the African plate below the European plate. The slab retreat causes a stretching of the overriding plate and triggered the opening of the Tyrrhenian basin. The sedimentary record described in the Tyrrhenian Basin spans from early-Miocene to the most recent Pleistocene deposits. The distribution of these sediments, their geometry and their relations with the tectonic structures reflects the basin evolution throughout the time. Oldest sediments consist in pre-Trotonian materials deposited at the Corsica and Sardinian Basins during their formation. Thus this region may have been opened previously to the Tortonian times. In fact, these basins formed as episutural basins during the early Miocene. The Tortonian unit has only been identified at the continental areas. The rifting onset took place during the Tortonian, as suggested by the sedimentary discontinuity described within this unit. Such discontinuity marks the base of the syn-rift wedges, and it is known at the literature as the "L" discontinuity. The Messinian deposit have been described at the continental and back-arc areas. Its presence at the Campania and Cornaglia Terraces (back-arc areas), where no Tortonian has been found suggest that they were formed in some moment during the early Messinian. But, in fact, Messinian strata show a clear post-rift character in these areas. Thus both terraces are provably formed during the Tortonian, concurrently to the rifting processes of the North Tyrrhenian. Thus, in the North Tyrrhenian extension occurred through rifting processes, leading to rotated blocks that can be well appreciated at the bathymetry. North-south trend of these blocks suggest that extension direction was mainly east-west. While at the same time, at the Cornagla and Campania Terraces, extensional processes become more complex. Continental extension took place in the southern Cornaglia, while at the center, at the north and at the Campania Terrace back-arc magmatic crustal accretion occurred. Instead, in the southern Cornaglia Terrace a limited amount of magmatic crustal accretion occurred. Finally, according to sedimentary syn-rift geometries, extension continued in all these areas during the Messinian, although extensional processes become attenuated. The Pliocene deposits are the first unit that can be found everywhere, including the deepest areas of the Vavilov and Magnaghi Basins. It has been divided into two sub-units and the discontinuity between them is known as the "X" discontinuity, and marks the end of this extensional stage. The Magnaghi Basin may have opened during the uppermost Messinian, as suggested by the pre-rift Messinian evaporites observed at the western half of this basin. Then, in a short time lapse, extensional locus continues its migration towards the east and the Vavilov basin opened at the lower Pliocene. Opening of these two basisn may have occurred during a short period as suggested by the absence of synrift deposits in the area. At the same time, extensional processes at the continental and back-arc regions ceased completely, as suggested by the intra-Pliocene unconformity. It implies that the former magmatic extensional regime changed to an essentially amagmatic extension. Finally, at the boundary between the Pliocene-Pleistocene a new jump in the extensional locus occurred. As in the former case, a new basin opened: the Marsili Basin. Concurrently, in a certain moment during the upper Pliocene, transpression- transtensional tectonics started along the Italian Margin region related with this trench migration towards the south-east, and reactivated the former extensional faults.
Esta tesis está centrada en los procesos que tuvieron lugar en el mar Tirreno, el cual es una cuenca Neógena perteneciente al Dominio del Mediterraneo Occidental. Su formación está relacionada con el sistema de subducción de la placa Africana por debajo de la placa Europea. El retroceso del slab da lugar a un estiramiento en la placa superior provocando la apertura de la cuenca del Tirreno. El registro sedimentario descrito en el Tirreno abarca desde el Mioceno inferior hasta el Pleistoceno mas reciente. La distribución de estos sedimentos, su geometría y su relación con las estructuras tectónicas reflejan la evolución de formación de la cuenca a lo largo del tiempo. De acuerdo con la interpretación tectónica y la distribución de los depósitos sedimentarios, las sub-cuencas de Córcega y Cerdeña se formaron durante el Mioceno inferior como cuencas episuturales relacionada con el frente de subducción. Durante el Tortoniense la extensión migró hacia el este y los procesos extensivos empezaron en lo que sería el actual región del Tirreno Norte dando lugar a extensión continental. Mientras que en el sur los processos extensivos tomaron un carácter mas complejo que en el norte. En las zonas de Cornaglia Terrace y Campania Terrace tuvo lugar la formación de corteza oceánica nueva por acreción magmática, excepto en la parte mas meridional de la Cornaglia Terrace, donde tuvo lugar extensión continental con un pequeño aporte magmático. Durante el Messiniense, los procesos extensionales se atenuaron y en el Plioceno inferior cesaron casi por completo. Mientras que al mismo tiempo la extensión migró hacia la actual cuenca de Magnaghi y la cuenca de Vavilov, donde se dio ruptura cortical y exhumación del manto. Finalmente, en el límite Plioceno-Pleistoceno la extensión cesa en esta área y vuelve a migrar hacia la actual cuenca de Marsili.

Abstract:
Abstract The successful discovery of petroleum exploration primarily depends on the understanding of the basin evolution and sedimentary filling though geological time. Well data also play a key role for reservoir presence and quality analysis; however, none of well fully penetrated the Oligocene Syn-rift sequence in the West Arthit area. Therefore, this study aims to overcome the challenge of limited well information by performing the Forward Stratigraphic Modeling (FSM) to determine basin evolution, depositional setting, and reservoir distribution in this area. The FSM model is constructed with the inputs of paleo-bathymetry, subsidence, sediment supply, water level, and climatic cycle. In addition, the stratigraphic sequence is reproduced based on field observations such as rock samples, seismic mapping, well-log responses, and publications from nearby areas. The main uncertainty of building the FSM model is the initial age of rifting phase due to a lack of well penetration that fully covered the Syn-rift sequence and the limited biostratigraphic data. Therefore, two different age scenarios are examined in this study analogue from the age model as it was published in the Malay Basin locating to the south of study area. Once the FSM model was built, the last step was to calibrate the prediction result with the actual well result and the conventional seismic data to achieve the best accuracy and to increase the confidence on using the model. The FSM model was successfully reproduced the stratigraphic successions of the Syn-rift sequence in West Arthit area. The base case model was chosen from the age scenario of 27.0-23.1 Ma which exhibited four major cyclicities and matched with seismic mapping. The study area had two depocenters, one in the northwest and another one in the southeast. The northern sub-basin was deepened earlier during the first rifting phase whereas the southern sub-basin was subsided later after the second rifting period. With the increase in sedimentation rate and subsidence rate during the third rifting phase, both depocenters were shallowed up and then become a shallow lake covering the whole study area. The last lifting phase coincided with the thermal subsidence that occurred and affected across the region; therefore, the regional extensive lacustrine accumulated in the study area. The results from this study provided a crucial information on petroleum system especially depositional architecture, reservoir distribution, and potential source rock identification, which were incorporated into the planning of future exploration targeting in this field. This study demonstrates the new innovative approach to determine the basin evolution and to understand the variation on depositional setting in the study area with limited well data. This approach also creates the project value by supporting the planning of future exploration and development wells. Furthermore, this technique can be applied to all projects to increase the discovery rate and to add the field reserves.

Full text
Abstract:
The evolution of the 2000 km long Mesozoic rift system underlying the Labrador-Baffin Seaway is described, with emphasis on results from geophysical data sets, which provide the timing, sediment thickness, and crustal structure of the system. The data sets include seismic reflection and refraction, gravity, and magnetic data, with additional constraints provided by near-surface geology and well data. Many features that characterize rift systems globally are displayed, including: wide and narrow rift zones; magma-rich and magma-poor margin segments; exhumation of continental mantle in distal, magma-poor zones; and occurrences of thick basalts, associated with the development of seaward-dipping reflectors, and magmatic underplating. The magma-rich regions were affected by Paleogene volcanism, perhaps associated with a hotspot or plume. Plate reconstructions help elucidate the plate tectonic history and modes of rifting in the region; however, many questions remain unanswered with respect to this rift system.

Abstract:
The Labrador Sea formed during rifting between North America and Greenland beginning in the Early Cretaceous, with subsequent seafloor spreading from the Maastrichtian (chron C31) to Early Paleocene (chron C27n) that ended by chron C13 (earliest Oligocene). Early Cretaceous rifting resulted in accumulation of Alexis Formation basalt units and Bjarni Formation nonmarine and marginal marine clastic rocks. In the Late Cretaceous, extension focused further offshore as sag basin conditions formed across the shelf, with a basinwide transgression of Markland Formation shale and localized Freydis Member sandstone development. A Middle Paleocene to Early Eocene regression formed Gudrid Formation shoreline sandstone units, with correlative Cartwright Formation marine shale units. This was followed by an Early Eocene transgression of the Kenamu Formation and Middle Eocene Leif Member shoreline development. During the Late Eocene through Pleistocene, transgression took place once again at the base of the Mokami Formation, with subsequent development of the partly correlative shallow-marine sandstone units of the Saglek Formation.

Full text
Abstract:
Sedimentary basins within the Labrador-Baffin Seaway are the product of rifting between Greenland and the paleo-North American Plate. Rifting started in the Early Cretaceous, with seafloor spreading initiated in the Paleocene and ending near the Eocene-Oligocene boundary. A change in the spreading direction in the latest Paleocene resulted in transform offsets in the Davis Strait and along fracture zones in Baffin Bay, with deformation in northern Baffin Bay during the Eurekan Orogeny. Since the stratigraphy of western Baffin Bay is poorly constrained, analogues are used from the well studied Labrador and West Greenland margins and exposures on nearby Bylot Island. The generally northwest-trending basement structures are infilled with Cretaceous strata, which are overlain by a seaward-thickening wedge of post-rift Paleocene to Middle Miocene sedimentary rocks. Finally, a thick Middle Miocene and younger interval blankets the deep water and oceanic crust, with clinoforms locally developed on the shelf.

Abstract:
Giant mafic dyke swarms and related large igneous provinces play an important role in the understanding of the tectonic evolution of ancient continents and supercontinents. The information available for well dated Paleoproterozoic dyke swarms and large igneous provinces in northern Canada is summarized in this synthesis, with an emphasis on their age, geographic distribution, paleomagnetism, and potential linkages to coeval magmatic events. Their tectonic settings, with a focus on links to rifting and continental breakup, are also discussed. Finally, the use of giant dyke swarms and large igneous provinces for testing paleocontinental reconstructions is considered, based mainly on paleomagnetism or on matching coeval magmatic events or sequences of magmatic events (magmatic barcoding) between cratons.

Abstract:
The Richardson Trough was a rift basin on the southern margin of an ancestral Iapetus Ocean. It was part of a complex paleogeography that included at least two major rift basins on western Franklinian and northern Cordilleran continental shelves. This paleogeography included the Ogilvie Arch, Porcupine Platform, Blackstone 'supra-basin', Babbage Basin, Husky Lakes Arch, Richardson Trough, Mackenzie Arch, Lac des Bois Platform, and the White Mountains and Campbell uplifts. The Richardson Trough was the failed arm of a triple rift system that formed when an early Paleozoic Iapetus Ocean developed north of the trough. The Richardson Trough displays a classic 'steer's head' profile with two rift fill cycles. The first features late early to middle late Cambrian rifting and late late Cambrian to late Early Ordovician post-rift subsidence; the second, late Early Ordovician to early Silurian rifting and late early Silurian to early Middle Devonian post-rift subsidence. Lower Paleozoic strata exposed in the Richardson Trough range in age from middle Cambrian to early Middle Devonian and are similar to strata in their sister rift, the Misty Creek Embayment. Before this study, the stratigraphic units defined for the Richardson Trough were the Slats Creek Formation and the Road River Formation. Here, the Slats Creek Formation and a new Road River Group are recognized. In order, this group consists of the middle and/or late Cambrian to Early Ordovician Cronin Formation; the early Early Ordovician to latest early Silurian Mount Hare Formation; the early Silurian to late Silurian Tetlit Formation; and the late Silurian to early Middle Devonian Vittrekwa Formation. These Road River Group strata are unconformably overlain by the late Middle to Late Devonian Canol Formation (outcrop) and by the Early Devonian Tatsieta Formation (subsurface).

Abstract:
The stratigraphy and the geological evolution of the West Greenland margin from the Labrador Sea to Baffin Bay in both the onshore and offshore areas are described. The primary data sets include seismic reflection surveys, wells, and outcrops. In addition, seabed samples, seismic refraction and magnetic data, onshore and offshore maps, and stratigraphic compilations were used. The basins of the West Greenland continental margin are described in three regions from the south to the north: southern West Greenland basins, central West Greenland basins, and northern West Greenland basins. Each region includes a description of the stratigraphy and evolution from the Archean to the Quaternary, divided into six phases: pre-rift and early extension, early rift, subsidence and rifting, late rift, drift, and post-drift. Finally, the regions are correlated and described in a tectonostratigraphic context together with analogues from the Canadian conjugate margin.
