Résumé :
We give and analyze geological data that substantiate the validity division of Dnieper-Donets basin into two separate basins: Donets marginal-continental part that was opening from 793.00–590.75 Ma and Dnieper innerplatform with the disclosure in late Paleozoic – early Mesozoic (385.75–178.00 Ma). Territorially boundary between those margins passes between regional seismic profiles Lozovaja-Shebelinka-Staropokrivka and Mechebylovo-Bryhadyrivka. Donets Basin (Central Donbass) is a remnant continental margin of paleoocean Prototetis II, and north side of Donets basin up to the border of the Dnieper deflection – the remnant of the continental margin Prototetis I.

Résumé :
The continental margins of Australia provide an excellent natural laboratory for investigations of continental extension and break-up, with examples of failed rifts, multi-phase extensional systems, and volcanic and non-volcanic margins. The thick sedimentary cover across large parts, however, has hindered understanding of the deep crustal and lithospheric structure due to poor imaging. ION Geophysical has acquired deep, long offset seismic data across Australia’s North West Shelf, as well as the Bight Basin on Australia’s southern margin. These programs provide unique imaging of the deep basement structures and the complete overlying sedimentary section, and across all of the terrains from continental crust to oceanic crust. The authors’ interpretation of these data will be discussed in the context of existing models for continental extension and break-up and the resulting implications for the petroleum system: Models of hyper-extension and possible mantle exhumation will be discussed with regards to the Bonaparte, Browse and Bight basins. Multi-phase extension and the development of intra-sedimentary detachment horizons will be reviewed across many areas. Development of volcanic margins, including the effects of dynamic uplift and magmatic intrusions, will be investigated in the Exmouth Plateau. Creation of enough accommodation space to allow the deposition of the observed (~20 km) sedimentary sections in the Carnarvon and Bonaparte basins.

Résumé :
The increasing availability of 3D seismic data from sedimentary basins at volcanic and non-volcanic continental margins has provided fundamental new insights into both the storage and transport of magma in the continental crust. As global hydrocarbon exploration increasingly focuses on passive margin basins with evidence for past intrusive and extrusive igneous activity, constraining the distribution, timing and pathways of magmatism in these basins is essential to reduce exploration risk. Producing and prospective Australian passive margin basins where igneous systems have been identified include the Bight, Otway, Bass, Gippsland and Sorell basins of the southern margin. This paper reviews both the impacts of volcanic activity on sedimentary basin hydrocarbon prospectivity (e.g. advective heating, reservoir compartmentalisation and diagenesis), and the styles, distribution and timing of late Cretaceous–Recent extrusive and intrusive igneous activity along basins of the southern Australian margin, providing illustrative examples based on 2D and 3D seismic reflection data.

Résumé :
AbstractA thick succession of continental redbeds was deposited in a 50 km wide intra-arc basin on the Andean active continental margin in the Atacama region of northern Chile during early Cretaceous times. Upper Jurassic to early Cretaceous marine limestones were buried by the seaward progradation of a succession of coastal dunes, saline lakes and sandflats. Aeolian dune fields migrating towards the east across these coastal plains became stabilized by the growth of vegetation. Interdune alluvial areas between the sand dunes and dune fields developed into extensive alluvial braid plains which were in turn superimposed by alluvial fans. These fans were inundated by a regionally extensive saline lake produced by tectonic or volcanic damming of the sedimentary basin. This lake dried up leaving a large area of playa-lake mudflats. The climate was warm and semi-arid with a low and seasonal rainfall. Parts of the area supported a substantial vegetation of woody plants, together with a vertebrate fauna of dinosaurs, pterosaurs and crocodiles. The continental redbeds were derived from a volcanic source and were deposited on continental crust in a deep but narrow, north-south elongated, fault-bounded graben. This extensional basin formed in an intra-arc setting within an active andesitic volcanic chain. Upwards-coarsening sedimentary successions were the product of uplift of the fault-bounded margins of the basin.

Résumé :
The sedimentary basins in area of Việt Nam continental shelf are located along the deep fault systems between the folded Indochinese block and Việt Băc-Hoa Nam platform and with the transitional zone. Is means that the zone attenuated continental crust. Due to that extruction of the Indochinese block toward the SoustEast which wrenched in right, in addition, due to the appearance of the thermal anomaly, producing the activity of Bien Dong seafloor spreading axis and drift of Australian–New Guinea plate toward Nord-East, induced some geodinamic factors to form many sedimentary basins in margins of Biển Dong Sea, such as: rift, pressure, extension, vertical slide cliff, horizontal displacement and wrench. These geodinamic factors created favourable conditions to form, develop and deform the sedimentary basins in Việt Nam continental shelf, followed the pull- apart type mechanism. But each sedimentary basin had its type of mechanism which depended on the concrete place of its basin from the Indochinese block and the thermal anomaly in Bien Dong Sea. Beside, itsformed condition for gas hydrate accumulations in some basins.

Résumé :
ABSTRACT. This paper presents the results of satellite-derived gravimetry for Abrolhos Continental Shelf and the adjacent areas, States of Esp´ırito Santo and Bahia,Brazil, and discusses tectonic genesis of the sedimentary basins. The free-air and Bouguer anomalies on the continental shelf show a gradual increase from coast tocontinental shelf break. The total difference of 135 mGal indicates crust thinning of 4.5 km. The Bouguer anomaly increases beyond the shelf break and continues upto the abyssal plane. The total difference of 260 mGal suggests crustal thinning of 9.0 km. The studied area has two types of passive continental margin: 1) ES-typewith high continental slope, low and narrow continental rise, and high free-air and Bouguer anomalies; 2) SP-type with low continental slope, high and wide continentalrise, and low gravity anomalies. There are three types of sedimentary basins with different geologic structure and tectonic genesis: 1) Basins on the continental shelf,CSH-type; 2) Basin on the continental rise, CRS-type; 3) Continental rift basin, CRF-type. The CSH-type, as Esp´ırito Santo basin, has coherent free-air and Bougueranomalies 40 to 50 mGal lower than the adjacent areas. The sedimentary deposits are 2.0 to 2.5 km thick. The basement depression is sustained by mechanical strengthwithout isostatic compensation. The normal faults of basin border are limited within upper crust. The CRS-type, as Pedro Can´ario basin, has low local residual Bougueranomaly with difference of 40 mGal. The sedimentary deposits are more than 2.7 km thick. The continental side basin border is under isostatic compensation due todeep normal fault between continental slope and continental rise. The oceanic side border is sustained by mechanical strength of the basement. The CRF-type, BesnardPassage, is a continental rift basin originated from mantle pull-apart tectonism. The rift bottom is under complete isostatic compensation. The normal faults of the grabenborder continue to the mantle. The Moho depth along the rift is at least 6.5 km shallower than the adjacent areas.Keywords: satellite-derived gravimetry, Abrolhos Continental Shelf, sedimentary basin, crustal thinning, isostatic compensation. RESUMO. Este artigo apresenta os resultados da gravimetria por satélite para a Plataforma Continental de Abrolhos e as áreas adjacentes, ES-BA, e discute as gêneses tectônicas das bacias sedimentares. As anomalias ar-livre e Bouguer na plataforma continental mostram um aumento gradativo a partir da costa até a quebra da plataforma continental. A diferença total de 135mGal indica afinamento da crosta continental de 4,5 km. A anomalia Bouguer se apresenta além da quebra da plataformae continua até o assoalho abissal. A diferença total de 260 mGal sugere afinamento crustal de 9,0 km. Na área estudada, observam-se dois tipos de margem continental passiva: 1) Tipo ES com talude continental alto, elevação continental baixa e curta e anomalias ar-livre e Bouguer altos; 2) Tipo SP com talude continental baixo, elevação continental alta e extensa e anomalias gravimétricas baixas. Existem três tipos de bacias sedimentares com estrutura geológica e gênesis tectônicas diferentes: 1) Bacias na plataforma continental, Tipo CSH; 2) Bacias na elevação continental, Tipo CRS; 3) Bacia de rifte continental, Tipo CRF. O Tipo CSH, como a bacia do Espírito Santo, possui anomalias ar-livre e Bouguer coerentes 40 a 50 mGal mais baixas do que as áreas adjacentes. Os depósitos sedimentares são de 2,0 a 2,5 km de espessura. A depressão do embasamento é sustentada pela rigidez mecânica sem compensação isostática. As falhas normais das bordas de bacias são limitadas dentro da crosta superior. O Tipo CRS, como a bacia Pedro Canário, tem baixa anomalia Bouguer local com diferença de 40 mGal. Os depósitos sedimentares têm mais de 2,7 km de espessura. A borda da bacia do lado continental está sob compensação isostática devido à falha normal profunda entre talude continental e elevação continental. Aborda do lado oceânico é sustentada pela rigidez mecânica do embasamento. O Tipo CRF, Passagem Besnard, é uma bacia do rifte continental originada do tectonis mode distensão do manto. O fundo da bacia está sob compensação isostática completa. As falhas normais da borda do graben continuam até o manto. A profundidade da Moho ao longo do rifte é pelo menos 6,5 km mais rasa do que as áreas adjacentes.Palavras-chave: gravimetria por satélite, Plataforma Continental de Abrolhos, bacia sedimentar, afinamento crustal, compensação isostática.

Résumé :
At the limit of the East-Canadian continental margin there are three oil and gas regions from north to south: Labrador Sea shelves, margins of the Great Newfoundland Bank and the continental margin of Nova Scotia. In each of these distinguishing regions are a number of sedimentary basins completely plunging under the water. At the shelf of Labrador Sea distinguishing the following large sedimentary basins: Saglek, Hopdale and Havke, at the margin of Newfoundland Bank it is known the basins: Jeanne d’Arc, Flemish Pass and Orphan. At the Nova Scotia shelf there are Nova Scotian and Sable basins. It is remarkable at the lofty latitude like of Labrador Sea region the age of the productive sediments beginning from more ancient rocks (Paleozoic), than in basins situated in law latitude (Mesozoic). In consequence of this the stratigraphy diapason of oil and gas bearing of the north latitude is considerably wide. The prospect of oil and gas bearing in all region is related principally with continental slopes and turbidites sediments in its. Late Jurassic and early Cretaceous reservoirs would be the aim for deep drilling sediments. Wide distribution of late Cretaceous and early Tertiary prospects reservoirs of oil and gas is quite really so far as they are bedded in the shallow horizons. Also the prospect of oil and gas bearing at the margin of the basin is related to late Cretaceous and Tertiary sediments, to deposits of fan and diapirs salt.

Résumé :
Nowadays oil-gas exploration make a great contribution to the world oil-gas reserve increase. A series of deepwater passive continental margin basins are found in Northern Continental Slope of South China Sea. These basins consisted of thick Mesozoic and Cenozoic sedimentary strata with the characteristics of the major world deepwater oil-gas basins. As one of Cenozoic sedimentary basins in deepwater area of Northern Slope of South China Sea, Xisha Trough Basin developed 1500-8000m thick sedimentary strata, which are north-south zoning characteristics of thicker in the center and thinner both in the north and south sides of basin. In its evolutionary history there are two stages: One is Paleocene-Oligocene Rift with Continental River-Lake Facies sedimentary and the other is Miocene-Quaternary Depression with shallow sea-hemiplegic sedimentary. It has good petroleum geological conditions that source rocks consist of lacustrine mudstones, paralic mudstone, and marine mudstone, Tertiary high porosity and permeability deepwater fan reservoirs are the main reservoir, and structural traps and lithologic traps developed. In a word, it has good oil-gas exploration potential.

Résumé :
Detrital zircon of clastic rocks has been widely recognized as a powerful tool for the study of crustal uplift, which is of great significance for understanding multi-sphere interaction. However, young detrital zircons can only roughly constrain the depositional time of the strata, and commonly used zircon age probability density and kernel density estimations cannot provide sufficient evidence to reveal spatio-temporal differences in tectonic uplift. The basins developed in active continental margins usually contain abundant magmatic rocks, which can provide insights into basin evolution and crustal deformation when combined with sedimentary characteristics. In this study, we report detrital zircon ages of Late Mesozoic clastic rocks from the Boli Basin, being part of the Great Sanjiang Basin Group in eastern NE China, which is strongly affected by the Paleo-Pacific subduction. In conjunction with the age data of coeval magmatic rocks and potential sedimentary sources of basement rocks adjacent to the basin, the geochronologic results of this study provide solid evidence for the formation of the Boli Basin and the spatio-temporal evolution of the crustal uplift in northeastern China. The Boli Basin went through multi-phase tectonic evolution of syn-rift and post-rift stages, based on the zircon age data of clastic and igneous rocks. When the geographical distribution characteristics of potential sedimentary sources and their percentages of contribution are taken into account, two stages of eastward migration of the crustal uplift and two episodes of basin destruction caused by the tectonic extension and subsequent compression can be proposed for the Boli Basin. These processes were caused successively by the rolling back of the subducted Paleo-Pacific slab, the docking of the Okhotomorsk block along the eastern continental margin of East Asia, and the transition of the subduction zone by the collision of the Okhotomorsk block.

Résumé :
The Uruguayan continental margin was generated following the fragmentation of the Gondwana supercontinent and the subsequent opening of South Atlantic Ocean. It constitutes an extensive sedimentation area in which three sedimentary basins can be found: the Punta del Este Basin, the southernmost portion of the Pelotas Basin, and the poorly defined Oriental del Plata Basin. The aim of this work was the identification and characterization of the different seismic units (seismic facies, systems tracts, depositional sequences) for the sedimentary interval assigned to the Eocene in the Uruguayan continental margin. Sequence stratigraphy was used as a basin analysis method for this purpose, using a database that consisted of approximately 10,000 kilometers of 2D seismic sections, acquired in exploratory surveys in 2007 and 2008. The workflow included the recognition of stacking patterns and/or stratal terminations, the definition of genetically significant stratigraphic surfaces and, based on these, the identification of systems tracts and depositional sequences. Three depositional sequences were identified in the studied sedimentary interval. The basal sequence is composed of four depositional systems tracts, including falling stage, normal regression (lowstand and highstand) and transgressive deposits. The intermediate sequence only preserves lowstand normal regression deposits. The third sequence is composed by three depositional systems tracts, including lowstand, transgressive and falling stage deposits. ResumoA margem continental uruguaia foi gerada após a fragmentação do supercontinente Gondwana e a subsequente abertura do Oceano Atlântico Sul. Constitui uma extensa área de sedimentação em três bacias sedimentares: a bacia de Punta del Este, a porção mais ao sul da Bacia de Pelotas e a Bacia Oriental del Plata, pouco definida. O objetivo deste trabalho foi a identificação e caracterização das diferentes unidades sísmicas (fácies sísmicas, tratos de sistemas, seqüências deposicionais) para o intervalo sedimentar atribuído ao Eoceno na margem continental uruguaia. Com este objetivo, utilizou-se a estratigrafia de seqüencias como método de análise de bacias, tendo-se utilizado um banco de dados constituído por aproximadamente 10.000 km de seções sísmicas 2D, adquiridas em pesquisas exploratórias em 2007 e 2008. O trabalho incluiu o reconhecimento de padrões de empilhamento e/ou terminações estratais, a definição de superfícies estratigráficas geneticamente significativas, tendo-se efetuado com base nelas, a identificação de tratos de sistemas e seqüências deposicionais. Três seqüências deposicionais foram identificadas no intervalo sedimentar estudado. A seqüência basal é composta por quatro tratos de sistemas deposicionais, incluindo a fase de abaixamento do nível do mar, a regressão normal e depósitos transgressivos. A sequência intermediária apenas preserva os depósitos de regressão normais de nível de mar baixo. A terceira seqüência é composta por três tratos de sistemas deposicionais, incluindo depósitos de nível de mar baixo, transgressivos e de abaixamento do nível do mar.

Résumé :
Two 3D seismic reflection datasets from the West African and Brazilian continental margins were analysed to determine their architectural elements and to further the understanding of the sedimentary processes that control their morphology. The results suggest a strong influence of local slope variations on the sedimentary processes and depositional and erosional products within these complex deep water settings. The Niger Delta dataset is characterised by large channel-levee systems and thrust-related folds. The folds degrade by channel erosion and slope failure, which creates laterally discontinuous erosional surfaces on the crests and flanks of the anticlines and chaotic deposits at their bases. The type of slope failure depends on the length and morphology of the local slope, sediment properties and the presence of anisotropics, such as faults. The location and morphology of the channel-levee systems on the Niger Delta are affected by topographical effects associated with thrust-related folding. Fold-induced local changes in gradient cause turbidity currents to deposit sediment upstream of the folds and erode the seafloor downstream of them. This results in the formation of knickpoints along the present- day thalweg of a channel-levee system. A model for the formation and evolution of the knickpoints predicts that they migrate upstream and leave internal erosion surfaces and terraces with coarse sediments in the sedimentary record. They may be an important process by which channels cut through uplifting fold belts. The Espirito Santo Basin dataset is characterised by salt diapirs, slope failures, channels and canyons. Interaction of turbidity currents with variations in topography has led to the formation of large depressions, which occur above abrupt breaks in slope and in trails that follow underlying erosional channels. They are inferred to form by Froude-supercritical currents that become unstable as they encounter topographical irregularities, such as scarps and knickpoints. This leads to the formation of erosional scours and deposits similar to sediment waves, which, when confined within channels, appear as roughly circular depressions.

Résumé :
“El present és la clau del passat”. James Hutton (1788), amb aquesta prou coneguda asserció uniformista, posà els fonaments pel desenvolupament de la investigació geològica moderna des de la perspectiva actualista. L’estratigrafia es val d’aquest principi per interpretar l’origen de les formacions geològiques a partir de l’observació de processos i geometries actuals i subactuals. Alhora, la geomorfologia estudia els processos afaiçonadors del relleu per conèixer l’origen i l’evolució del paisatge actual. Conceptualment, aquesta Tesi se situa a cavall entre l’estratigrafia i la geomorfologia amb l’objectiu general de reconèixer el per què i el com de la variabilitat morfosedimentària dels marges continentals passius silicoclàstics a llarg termini. Per atènyer aquest objectiu adoptem la hipòtesi de partida següent: la variabilitat morfològica dels marges continentals silicoclàstics passius pot ésser classificada per categories de forma objectiva i sistemàtica. Les diferències morfològiques observades responen principalment a l’acció d’uns pocs processos sedimentaris claus. Els mètodes i conceptes emprats en aquesta Tesi són propis de la hidrodinàmica i la sedimentologia. L’observació detallada de la morfologia i l’estratigrafia dels marges continentals, junt amb l’estudi dels processos hidrodinàmics que les han generades i l’anàlisi de la variabilitat espaciotemporal de les condicions ambientals en què s’han format, permet establir lleis de transport geomòrfic, altrament dites lleis de la morfodinàmica. En els successius capítols d’aquesta Tesi abordem aquests aspectes mitjançant l’anàlisi de dades geofísiques de reconeixement del fons i del subsòl marins, amb un especial èmfasi en les xarxes de drenatge del talús continental i la conca profunda. Els resultats d’aquesta anàlisi se sintetitzen en el plantejament d’un model morfodinàmic predictiu sobre la forma del perfil longitudinal dels canyons submarins. Aquest model dóna peu a discutir sobre transitorietat i equilibri en les formes de drenatge observades a les dades geofísiques considerades. Així doncs, en aquest treball advoquem per la complementarietat i interdependència de les anàlisis observacionals i la modelització basada en la formulació teòrica de processos. Els principals resultats obtinguts en aquest treball demostren la possibilitat d’extreure informació sobre l’evolució de les conques sedimentàries a partir de l’estudi de les seves morfologies, tan modernes com relictes i fòssils, i indiquen la necessitat d’entendre els canyons submarins com a sistemes capaços d’evolucionar a partir de mecanismes netament deposicionals, a més dels mecanismes erosius ja prou coneguts. Aquests resultats es poden traduir en una millora de les prediccions estratigràfiques al talús continental, en un millor coneixement de la distribució de reservoris sedimentaris d’hidrocarburs o aigua en aquests ambients, i a replantejar els models establerts sobre el desenvolupament dels canyons submarins a escala global. La Tesi està formada per un compendi de quatre articles publicats en revistes pertanyents al Journal Citation Report de l’Institute for Scientific Information (JCR-ISI), i l’hem estructurada en set capítols. El Capítol 1 consisteix en una introducció general destinada a centrar el lector en el marc conceptual, geogràfic i metodològic en què s’ha elaborat l’estudi. Els capítols 2 a 5 corresponen als quatre articles publicats. El capítol 6 correspon a la síntesi i discussió general dels principals resultats presentats als quatre capítols anteriors. Al capítol 7 hi incloem un sumari de les conclusions més rellevants conjuntament amb algunes perspectives de futur sorgides arran d’aquest treball. Finalment, a l'Annex, hi incloem un treball de síntesi bibliogràfica on descrivim les principals característiques fisiogràfiques dels fons marins mediterranis.
Sedimentary morphodynamics of siliciclastic passive continental margins "The present is the key to the past". James Hutton (1788), with this well-known principle of uniformitarianism, established the basis of the modern geology by following the assumption of actualism. Stratigraphy makes use of this principle to interpret the origin of geological formations according to observations of modern and submodern processes and geometries. Geomorphology studies the processes that sculpt the Earth’s surface to understand the origin and evolution of present landscapes. The main objective of this Thesis, which is conceptually halfway between stratigraphy and geomorphology, is to understand the long-term morphosedimentary variability of siliciclastic passive continental margins. Our initial hypothesis is that the morphology differences among modern siliciclastic passive margins can be objectively and systematically categorized, and that these differences are mainly related to the action of a few key sedimentary processes. The methods and concepts we use in this study are based on hydrodynamics and sedimentology. The detailed observation of continental margin morphology and stratigraphy, the study of the hydrodynamic processes that control their evolution, and the analysis of changing environmental conditions through time and space facilitate the development of geomorphic transport laws (also known as morphodynamic flux laws) for predicting landscape forms and dynamics. In the following chapters we discuss these topics while analysing seafloor and subseafloor geophysical data, with a particular focus on submarine drainage networks. An important result of this analysis is a morphodynamic model that can explain the long-profile shape of submarine canyons. The model stimulates our discussion about the equilibrium and transience of drainage morphologies observed in the geophysical data set we present. In this work we advocate for the complementariness and interdependence of observational analyses and modeling of sedimentary processes. This Thesis demonstrates that much can be learned about the sedimentary evolution of submarine basins from the study of seascape morphologies, both modern and ancient, and that submarine canyons can evolve while remaining net depositional, beyond the broadened view of these features as purely erosive. These results can be translated to improved stratigraphic prediction in slope strata, a better knowledge of hydrocarbon and water resource distribution in these settings, and a broadened view of submarine canyon development.

Résumé :
The aims of this study are to extend the established high-resolution sequence stratigraphic framework of the Madison Formation of Wyoming and southern central Montana to the correlative and genetically-related Mississippian carbonate ramp, ramp margin, and basin strata of the central Montana trough and Antler foreland basin in order to examine and discriminate the controls on depositional processes and the resulting stratigraphic architecture through space and time in tectonically-active settings. An outcrop-based, high-resolution sequence stratigraphic study of two ramp-to-basin transects, one in central Montana and the other in southwestern Montana and east-central Idaho, is conducted in order to examine these deposits across two coeval margins with differing subsidence, hydrodynamic, and physiographic configurations and histories. Independent measurements of system response to global and local forcings allows disentanglement of primary controls on deposition and allows us to gain understanding of the roles and interplay of these controls, in particular eustasy and tectonics, on the system's architectural development. Conversely, insight into the geodynamic evolution of western North America, glacioeustatic changes, and variations in global climate and oceanographic systems during the greenhouse-to-icehouse transition is gained. A series of high-resolution sequence stratigraphic cross-sections and time-slices are produced incorporating outcrop measured sections and measured sections previously collected by members of the Comparative Sedimentology Laboratory in a series of transects across the Madison ramp system. A new chronostratigraphic framework for Madison carbonates is developed by using Lower Carboniferous delta C-13 isotope excursions as isochronous tie points between ramp-top, margin, and basinal sections. These delta C-13 excursion events have been documented to be time-invariant globally due to global changes in ocean chemistry. The results of the study include resolution and discrimination of sequential foreland basin subsidence, carbonate sediment production and progradation, subsidence and uplift of foreland basin structures along a carbonate shelf edge, diachronous subsidence of discrete depocenters, and eustasy.

Résumé :
Characteristic half-graben and graben geometries are generated by extensional tectonics. The sedimentary infill to such basins reflects their structural evolution. The actively extending basins of central Greece have provided an opportunity to study the mechanisms that control sediment distribution and the resultant facies patterns and geometries produced in such environments. The modern and precedent Neogene to Quaternary sediments studied, and their controlling processes, provide predictive templates for the analysis of controls acting upon ancient extensional basin fills. On a basinwide scale, facies patterns are controlled by the geometry of major basin-controlling normal faults and by the structural level of the basin - determining alluvial, lacustrine or marine environments. Increments of movement on normal faults tilt and vertically displace the depositional surface, producing facies responses in terms of fluvial/submarine channel avulsion or preferential migration into topographic lows, lake or sea coastline advance or retreat across the depositional slope, and the progradation of clastic wedges off fault scarps and uplifted areas. The time-averaged product in the stratigraphic record is typically of clinoforms developed preferentially against basin margin faults and axial channel systems concentrated in the structurally constrained depocentre(s). Such gross morphologies are seen in the Lower Pliocene early rift history of the Corinth asymmetric graben; conglomerate-dominated fan deltas and alluvial fans prograded laterally into the basin. The progradation of an ophiolite-derived, fluvio-deltaic system along the basin axis illustrates the competition of sediment supply rates with tectonic subsidence rates in determining facies geometries. A number of other controls on sediment distribution are variously important through time within extensional basins, in addition to structuration and sediment supply rates (itself a function of hinterland litho-type and structural evolution). These include eustatic and climatic variation and compactional subsidence rates. The Corinth Isthmus has been studied with the aim of establishing the interaction of concurrent tectonic and eustatic relative base-level changes. Computer-modelling of the migration of a coastline through theoretical stratigraphic sections illustrates the effects of varying rates of change of sea-level, tectonic subsidence (or uplift) and deposition with time. Incorporation of the global sea-level curve for the Late Quaternary into such models reasonably predicts observed facies geometries in the Late Pleistocene and Holocene of the Isthmus. U-series disequilibrium dating of corals from the Corinth Canal area has constrained transgressive beach sub-sequences as reflecting c. 100,000 year wavelength eustatic cycles. After subtraction of depositional levels constrained in time and space against the sea-level curve, an average net uplift rate is derived for the central Isthmus of more than 0.3m per 1000 years. The areal distribution of Late Pleistocene marine facies in the southern Corinth Basin is principally controlled by the structural form and evolution at time of deposition. Subsequent tilt block faulting in an alluvial environment illustrates how intrabasinal fault block morphologies may generate axial and lateral sediment transport systems analagous to those on a basinwide scale. The competition between process rates is emphasized. Three- dimensional sedimentary facies patterns within evolving syn-rift basins are shown to be dependent upon the interaction of three principal factors: a) the rate of tectonic displacements through time, on both basinwide and local fault block scales, b) the rate of sea-level change through time (or lake-level change, whether determined by tectonic or climatic means), and c) the rate of deposition at any locality, itself a function of hinterland structure and lithology, climate and depositional geometries.

Résumé :
Deepwater continental margins constitute one of the ultimate exploration frontiers where giant oilfields have been discovered. These comprise reservoirs units affected by multi‐scale compartmentalisation resultant from stratigraphic, structural and/or diagenetic processes that compromise the lateral and/or vertical connectivity of permeable strata. A 3D seismic dataset from the deepwater Espírito Santo Basin (SE Brazil) was analysed to assess and quantify the architectural elements that influence the compartmentalisation of reservoir units. Mass‐Transport Deposits (MTDs) have growing importance on reservoir studies as they highly impact the compartmentalisation of contemporaneous reservoir‐prone turbidite strata. More significant compartmentalisation occurs in areas with higher MTD proportion, which are associated to wider dimensional ranges of laterally limited turbidites. However, salt diapirs constitute important barriers for MTD erosion, thus aiding the preservation of reservoir‐prone turbidites. The internal compositional heterogeneities and cohese strata on remnant and rafted blocks identified within the studied MTDs constitute important fluid flow or accumulation compartments, particularly when linked to underlying permeable faults. Submarine channels in Palaeocene and Neogene Units comprise important reservoir‐prone strata, thus it is crucial to understand their spatial distribution. Large channels are focused along the axis of salt‐withdrawal basins, whereas in sub‐units with numerous smaller channels these are laterally scattered across the basin. A new quantitative method used in this study shows that channel confluences and topographic confinement control significantly the density and spatial distribution patterns of submarine channels. A novel classification for submarine channel confluences is proposed, based on channel morphology and distribution of sediment facies within the tributaries. The key aim of this thesis was to undertake a seismic‐scale qualitative and quantitative analysis of the compartmentalisation of reservoir units on the Brazilian margin using methodologies that can be applied to other continental margins worldwide. As such, the results of this study can provide significant contributions for hydrocarbon exploration.

Résumé :
A comprehensive geophysical survey dataset from the continental shelf of northeastern Svalbard is analysed for the first time in order to investigate the seafloor geomorphic and sedimentary records of glaciation in the area, and to interpret this information in the context of large-scale ice sheet development. High-resolution swath-bathymetric data, used together with co-located 3.5 kHz sub-bottom profiler records and geological core records, are used to characterise and map submarine glacigenic landforms. Process-based interpretations are used to group these data into landsystem models, which are then used to reconstruct former ice-sheet behaviour and dynamics during the Late Weichselian (30-10 kyr B.P.). Absolute flow directions suggest that flow was towards the east and northeast in areas south of the Kvitøya Trough, and northwards towards the shelf break in the trough itself. On the basis of these data, new ice-sheet reconstructions are presented for this sector of the former Svalbard-Barents Sea Ice Sheet and include the suggestion that the former ice centre was located significantly further west than in previous reconstructions. A fast-flowing Kvitøya Trough ice stream draining a significant internal ice basin did not exist. Two further datasets are considered. First, a TOBI side-scan sonar dataset collected over the Hinlopen Slide scar provides detailed imagery of this grant submarine slope failure, which is located in a glacier-influenced, outer shelf setting. Through a systematic analysis of meso-scale morphological features (m to km scale) new insights into the composition of slide scarps and deposits are gained and small-scale post-slide processes are identified. Lastly, a 3D seismic dataset from the Murzuq Basin, Libya, which images an ancient (~440 Myr B.P., Late Ordovician) glacigenic succession, is also analysed. By considering the architecture of the deposits and their glaciological setting in an inner shelf, inter-ice stream area, modern analogues for the glacier-related sediments are identified.

Résumé :
Rifted continental margins are economically important regions of Earth. Many of these margins are a product of multiple phases of rifting, where structural inheritance plays a role in subsequent deformation. The Northern Carnarvon Basin of Australia’s North-West Shelf is an example of a polyphase margin that has undergone several episodes of extension in the Palaeozoic to Early Cretaceous. This thesis presents original regional scale interpretations of publicly available seismic data from the inboard margin of the Northern Carnarvon Basin. This work shows two distinct orientations of Palaeozoic structures providing evidence for a polyphase Palaeozoic rift history of the basin. These structural trends influence the subsequent fault patterns associated with Mesozoic rifting. Two-dimensional, isothermal mechanical numerical experiments are used to test seismic observations by forward modelling lithospheric extension at a polyphase continental margin. These experiments document different modes of deformation including “narrow rifts” and “wide rifts” and a dual mode of extension with coeval narrow and wide rift attributes. These experiments potentially shed light on the crustal structure of the Northern Carnarvon Basin, revealing that the dual mode of extension observed could be the result of the removal of the lower crust adjacent to the Pilbara craton and subdued extensional strain rate in the Exmouth Plateau. Three-dimensional ‘numerical sandbox’ experiments where inherited structures are at varying degrees of obliquity to the imposed extension direction are also presented. These experiments generate complex time-dependent deformation patterns. Learnings from this work demonstrates that the Mesozoic deformation patterns of the Northern Carnarvon Basin can be explained by just one extension vector associated with the rifting of Greater India and that the rifting of the Argo block potentially had little effect on the first order deformation patterns of the basin.

Vários trabalhos têm tentado abordar a evolução das margens conjugadas do Atlântico, incluindo o nordeste do Brasil e o oeste da África. Entretanto, o avanço de pesquisas anteriores tem sido dificultado em razão da falta de dados na região marginal da porção oriental do nordeste do Brasil, principalmente na área inserida entre a Zona de Cisalhamento de Pernambuco e o Alto de Touros. Este fato tem imposto limitações ao desenvolvimento de modelos regionais sobre a evolução geotectônica e paleogeográfica desta região, assim como na correlação com sua contraparte na África. Nesta dissertação é apresentada uma investigação realizada com base em dados gravimétricos, magnéticos e sísmicos regionais. Os resultados mostraram que esta região representa um alto do embasamento com a orientação regional das principais estruturas tectônicas (ENE-WSW), ortogonais as estruturas desenvolvidas durante o processo de abertura das bacias da Paraíba e da Plataforma de Natal (NNE-SSW e NNW-SSE). Sobre o embasamento continental formou-se uma plataforma estreita com uma cobertura sedimentar pouco espessa (0,8-2,5 km) e uma quebra abrupta da plataforma, criando uma vasta zona de bypass através do talude. A análise de uma seção sísmica profunda revelou que a crosta continental afinada (crosta transicional) representa uma estreita zona e que o limite crosta continental-oceânica (COB) está localizado a aproximadamente 100 km a leste da atual linha de costa, na Bacia da Paraíba, e a 70 km, na Bacia da Plataforma de Natal. A modelagem geofísica, integrada com a interpretação sísmica, indica que esta região é caracterizada por um afinamento abrupto da crosta continental, com a consequente ascensão súbita da Moho. Também há evidências da existência de uma zona de crosta continental extremamente afinada, a qual foi interpretada como crosta proto-oceânica. Estes novos dados demonstram que esta área apresenta fortes similaridades com margens rifteadas não vulcânicas ou pobres em magma.
Several studies have tried to address the evolution of the Atlantic conjugate margins, including Northeast Brazil and West Africa. However, past research advances has been hindered by a lack of data for the marginal region in the eastern portion of northeastern Brazil, extending from the Pernambuco Shear Zone to the Touros High. This situation has imposed serious limitations on the development of a regional view of the geotectonic and paleogeographic evolution of this area and on correlations with regional counterparts in Africa. Here, we present an investigation using regional gravimetric, magnetic and seismic data. The results show that this region represents a basement high with regional orientation of tectonic structures (ENE-WSW) orthogonal at structures developed during the open processes of the Paraíba and Natal Platform Basins (NNE-SSW and NNW-SSE). The continental basement forming a narrow platform with a thin sedimentary cover (0.8-2.5 km) and an abrupt shelf break, which created a large bypass zone towards the slope. The analysis of a deep seismic section revealed that thinned continental crust (transitional crust) occupies a narrow zone and that the continental-oceanic boundary (COB) is located approximately 100 km to the east of the present coastline, at Paraíba Basin, and 70 km, at Natal Platform Basin. Geophysical modeling integrated with interpretation of the seismic data suggests that this region is characterized by an abrupt thinning of continental crust, with an accompanying sudden rise of the Moho. There are also indications for the existence of a zone of extremely thinned continental crust, which was interpreted as protooceanic crust. Our findings suggest that the study area shows strong similarities to nonvolcanic or magma-poor rifted margins.

The shelf of the East-Siberian Sea remains the least explored part of the Arctic region. At the same time, the geological and geophysical work performed in the last decade on oil and gas and on the problem of determining the outer boundary of the continental shelf indicate high prospects for the promising oil and gas bearing area of the De-Long rise and areas of the continental slope identified here. The main prospects are associated with zones of development of clinoform complexes and fan lobes within the continental slope and structures in the Mesozoic-Cenozoic sedimentary section on the eastern margin of the De-Long rise.

Texte intégral
Résumé :
The Finlayson Lake district in southeastern Yukon is composed of a Late Paleozoic arc-backarc system that consists of metamorphosed volcanic, plutonic, and sedimentary rocks of the Yukon-Tanana and Slide Mountain terranes. These rocks host >40 Mt of polymetallic resources in numerous occurrences and styles of volcanogenic massive sulphide (VMS) mineralization. Geochemical and isotopic data from these rocks support previous interpretations that volcanism and plutonism occurred in arc-marginal arc (e.g., Fire Lake formation) and continental back-arc basin environments (e.g., Kudz Ze Kayah formation, Wind Lake formation, and Wolverine Lake group) where felsic magmatism formed from varying mixtures of crust- and mantle-derived material. The rocks have elevated high field strength element (HFSE) and rare earth element (REE) concentrations, and evolved to chondritic isotopic signatures, in VMS-proximal stratigraphy relative to VMS-barren assemblages. These geochemical features reflect the petrogenetic conditions that generated felsic rocks and likely played a role in the localization of VMS mineralization in the district. Preliminary in situ zircon chemistry supports these arguments with Th/U and Hf isotopic fingerprinting, where it is interpreted that the VMS-bearing lithofacies formed via crustal melting and mixing with increased juvenile, mafic magmatism; rocks that were less prospective have predominantly crustal signatures. These observations are consistent with the formation of VMS-related felsic rocks by basaltic underplating, crustal melting, and basalt-crustal melt mixing within an extensional setting. This work offers a unique perspective on magmatic petrogenesis that underscores the importance of integrating whole-rock with mineral-scale geochemistry in the characterization of VMS-related stratigraphy.
