Outcrop Atlas And Field Guide For Sepm Research Conference Stratigraphic Evolution Of Deep Water Architecture

This large format (11 x 17 inch) all color outcrop atlas and field guide was produced for the SEPM Research Conference held in Chile in February, 2009. It contains a wealth of information on the world class deep water outcrops of the Cretaceous of the Magallanes Basin in the Ultima Esperanza District, Chilean Patagonia. This book covers the significant outcrops in the region the Punta Barrosa Formation, CerroToro Fm., and the Tres Pasos Fm.

This dissertation comprises three chapters focusing on the evolution of marine sedimentary successions that formed as the fill of large submarine channel belts and their tributary systems. These channel belts serve as conduits for gravel- and sand-laden sediment gravity flows along the axes of narrow, elongate foreland basins. In the past, axial channel belts have not been widely recognized in submarine foreland basins (Mutti et al., 2003). However, recent studies have demonstrated the presence of axial channels, 3-8 km in width and > 100 km in length, in a number of marine foredeeps including the Cretaceous Magallanes Basin, southern Chile, and the Tertiary Molasse Basin, northern Austria (De Ruig and Hubbard, 2006; Hubbard et al., 2008, 2009). Additional studies have shown that similar channels are common in submarine trough-shaped basins in other convergent margin settings such as the Peru-Chile trench (Thornburg et al. 1990, Völker et al., 2006), the Hikurangi trough, offshore New Zealand (Lewis and Pantin, 2002), and the Nankai trough, offshore Japan (Fig. 1 in Moore et al., 2007), as well as in modern oceanic rift basins, such as the Maury channel in the Northeast Atlantic Rockall Basin (Cherkis et al., 1973) and the Northwest Atlantic Mid-Ocean Channel (NAMOC) in the Labrador Sea (Hesse et al., 1987, 1990; Hesse, 1989, Klaucke et al., 1998). These occurrences suggest that axial channels may be common sediment transport fairways in elongate deep-water basins in a variety of tectonic settings. This thesis investigates the sedimentary evolution, stratigraphic architecture, and paleogeography of such channel systems in two distinct, yet analogous and complementary research areas: the Magallanes foreland basin in southern Chile, and the Molasse foreland basin in northern Austria. The main objectives of this study are: a)to characterize the processes of submarine sediment transport and deposition in the study areas, b)to explain the associated filling patterns of ancient submarine axial channels and their tributaries, and c)to reconstruct the paleogeography of an ancient seafloor in order to better understand deep-marine sediment dispersal patterns in narrow elongate basins. The Magallanes Basin is a retro-arc foreland basin characterized by a deep-marine filling history from the Cenomanian/ Turonian (Fildani et al., 2003; Fosdick et al., in press) to the Campanian (Chapter 3). The numerous coarse-grained submarine channel and lobe complexes of the Turonian to Campanian Cerro Toro Formation represent a large north-south oriented channel belt that funneled sediment gravity flows along the axis of the foreland basin parallel to the active thrust front (Hubbard et al., 2008). This main axial trunk channel belt was probably fed by at least one, and possibly numerous, tributary channel systems coming off the Andean mountain front to the west. Similarly, sedimentation within the Upper Austrian Molasse Basin during the late Oligocene to early Miocene was largely controlled by an axial trunk channel that was fed by a deltaic system to the west and a tributary system lying along the Inntal fault zone to the southwest (De Ruig and Hubbard, 2006). Three studies were undertaken in order to illuminate the processes and architecture of the fill of submarine foreland basin axial channels: the interaction of submarine debris flows and turbidity currents within the axial channel in the Molasse Basin (Chapter 1), the stratigraphic and architectural evolution of coarse-grained deep-water deposits in a tributary system setting in the Magallanes Basin (Chapter 2), and the paleogeography of the Magallanes Basin axial channel belt and its tributary system and the associated basin-filling pattern over time (Chapter 3). Multiple techniques were combined to achieve these goals, including field mapping, sedimentological analysis of outcrops and rock cores, interpretation of wireline logs and 3D seismic-reflection data, U/Pb dating of zircons, strontium isotope stratigraphy, and a novel approach to lithofacies proportion modeling (Stright et al., 2009).

A September 2001 meeting held in Nice, France, examined current knowledge on confined turbidite systems, in particular the Gr s d'Annot. Work from the meeting covers aspects such as structural geology, sedimentary geology and sequence stratigraphy, modeling of sedimentary processes and architectures, geochemistry, reservoir characterization, seismi

An examination of ancient and contemporary submarine landslides and their impact Landslides are common in every subaqueous geodynamic context, from passive and active continental margins to oceanic and continental intraplate settings. They pose significant threats to both offshore and coastal areas due to their frequency, dimensions, and terminal velocity, capacity to travel great distances, and ability to generate potentially destructive tsunamis. Submarine Landslides: Subaqueous Mass Transport Deposits from Outcrops to Seismic Profiles examines the mechanisms, characteristics, and impacts of submarine landslides. Volume highlights include: Use of different methodological approaches, from geophysics to field-based geology Data on submarine landslide deposits at various scales Worldwide collection of case studies from on- and off-shore Potential risks to human society and infrastructure Impacts on the hydrosphere, atmosphere, and lithosphere

This book gives practical advice and ready to use tips on the design and construction of subsurface reservoir models. The design elements cover rock architecture, petrophysical property modelling, multi-scale data integration, upscaling and uncertainty analysis. Philip Ringrose and Mark Bentley share their experience, gained from over a hundred reservoir modelling studies in 25 countries covering clastic, carbonate and fractured reservoir types. The intimate relationship between geology and fluid flow is explored throughout, showing how the impact of fluid type, production mechanism and the subtleties of single- and multi-phase flow combine to influence reservoir model design. Audience: The main audience for this book is the community of applied geoscientists and engineers involved in the development and use of subsurface fluid resources. The book is suitable for a range of Master’s level courses in reservoir characterisation, modelling and engineering. · Provides practical advice and guidelines for users of 3D reservoir modelling packages · Gives advice on reservoir model design for the growing world-wide activity in subsurface reservoir modelling · Covers rock modelling, property modelling, upscaling and uncertainty handling · Encompasses clastic, carbonate and fractured reservoirs
