By S. A. Lomas
This booklet arose from a turning out to be appreciation of the level to which the advance of turbidite depositional platforms is essentially stricken by basin-floor topography. in lots of turbidite structures and turbidite hydrocarbon reservoirs, depositional styles were reasonably to strongly limited by means of pre-existing slopes; hence 'submarine fanatics' will be faraway from fan-shaped the place restricted through major bathymetric gains. This quantity examines elements of sediment dispersal and accumulation in deep-water platforms the place sea-floor topography has exerted a decisive keep watch over on deposition, and explores the linked controls on hydrocarbon reservoir structure and heterogeneity. The papers awarded right here supply an international point of view, that is wide-ranging by way of procedure in addition to place, together with contrasting stories and case reviews of outcrop, subsurface, sleek and experimental platforms. This ebook can be of use either to educational geologists and to geoscience execs in facing the characterization/modelling of deep-water clastic reservoirs. additionally to be had: Alluvial lovers: Geomorphology, Sedimentology, Dynamics (Geological Society specified booklet) - ISBN 1862391890 Western North Atlantic Palaeogene and Cretaceous Palaeoceanography - ISBN 1862390789 The Geological Society of LondonFounded in 1807, the Geological Society of London is the oldest geological society on the earth, and one of many greatest publishers within the Earth sciences.The Society publishes a variety of top quality peer-reviewed titles for teachers and execs operating within the geosciences, and enjoys an enviable overseas attractiveness for the standard of its work.The many components during which we post in include:-Petroleum geology-Tectonics, structural geology and geodynamics-Stratigraphy, sedimentology and paleontology-Volcanology, magmatic experiences and geochemistry-Remote sensing-History of geology-Regional geology courses

Stanford Geological Atlas Of Great Britain And Ireland -1907
Excerpt from Stanford's Geological Atlas of significant Britain and eire: With Plates of attribute FossilsThe scope of this paintings has been enlarged by means of the addition of a cartoon of the geological good points of eire, its counties and major strains of railway; and the topic is illustrated through a geological map of the rustic, and via 3 illustrations borrowed from Professor E.
This quantity is a set of papers, preceded by means of an introductory essay, on coastal physiography. all of the authors have made major contributions to the topic. they're of other nationalities and the papers are, intentionally, no longer all contemporary ones. during this booklet emphasis has been laid totally on concerns that are of basic instead of neighborhood or perhaps neighborhood price.

Connected tortuous corridor model Two-dimensional sections of continental margins in which mobile salt has produced complex slope topographies commonly appear similar to sections through the Gulf of Mexico PlioPleistocene slope deposits. g. Fig. 11). Thus, as in the silled sub-basin case, seismic facies exhibit convergent thinning and convergent baselap geometries adjacent to syndepositional salt-related highs. Two-dimensional seismic data are commonly all that is available during the early phases of exploration.
