Download or read book Shelf Width Variability Controls Sediment Dispersal on Active Margins written by Emily Wei and published by . This book was released on 2019 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-resolution CHIRP and multi-channel seismic data paired with sediment cores provide an unprecedented view of forcing functions on continental margin deposits. Serving as reservoirs for hydrocarbons, sand, and aquifers, continental margin deposits have societal and scientific relevance. Traditionally, relative sea-level and sediment supply are considered the dominant controls on the geometry of continental shelf deposits. On active margins studied in this dissertation, tectonic deformation plays a large role in controlling shelf geometry, as deformation is at high angles to the shoreline. Sediment storage and dispersal are modified further by energetic oceanographic currents and climate. In the Gulf of Papua (GoP), clinothem architecture and surfaces of lap are not dependent on eustatic sea level changes. As a result of foreland basin tectonics, subsidence in the northeast GoP engenders aggradational Holocene clinoforms whereas peripheral bulge uplift in the southwest GoP causes toplap. Along-margin currents build the clinothem obliquely to the northeast. Downcore clay mineralogy constrain contributions of the Fly and Purari rivers to the GoP clinothem and lowstand deep-water basin deposits. Results suggest that sediment source and routing changed through a sea level cycle. Fly River sediment may have bypassed the inner mid-shelf clinothem during intermediate lowstands due to narrower shelf widths that allow for the establishment of incised valleys. Depocenters of post-glacial shelf deposits offshore of the Oceano Dunes State Vehicular Reservation in Central California are influenced by eustatic sea-level changes in the cross-shore direction and uplift of the San Luis Block and subsidence of the Santa Maria Basin in the along-margin direction. The timing and emplacement of turbidite deposits from submarine canyon systems offshore of San Onofre (SO) and Dana Point (DP) may be controlled primarily by shelf width. Wide shelves offshore of SO were formed by transpression along the right-lateral Newport-Inglewood/Rose Canyon Fault Zone. Turbidites offshore of SO were deposited during and prior to the last sea-level lowstand, whereas turbidites were deposited offshore DP through the sea-level transgression and highstand. Second-order controls on local turbidite emplacement include small synclines and anticlines that engender deposition or promote sediment bypass.

Download or read book Continental Shelves of the World written by F.L. Chiocci and published by Geological Society of London. This book was released on 2014-11-06 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's continental shelves are the sites of vast resources of food, energy and minerals, the exploitation of which is continuously increasing. Fluctuating global sea levels throughout the Quaternary period produced multiple transgressive and regressive cycles that profoundly affected and shaped these shelves. The complex interactions among climate, sea level, tectonics, oceanography and sediment input have formed distinctive sediment packages on each shelf and provide a guide to the interpretation of older shelf sequences throughout the geological record. This Memoir compiles studies on 23 selected shelves from all the continents, focusing on their evolution and examining the patterns of sedimentation during the past approximately 125 000 years. In addition to providing basic background information for each area, the chapters consider specific aspects of continental shelf research, from seismic stratigraphy to geomorphology, from palaeoceanography to palaeo sea-level reconstruction and from palaeontology to geochemistry.

Download or read book Subaqueous Mass Movements and Their Consequences written by A. Georgiopoulou and published by Geological Society of London. This book was released on 2020-07-08 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: This GSL volume focuses on underwater or subaqueous landslides with the overarching goal of understanding how they affect society and the environment. The new research presented here is the result of significant advances made over recent years in directly monitoring submarine landslides, in standardising global datasets for quantitative analysis, constructing a global database, and leading international research projects. This volume demonstrates the breadth of investigation taking place into subaqueous landslides, and shows that while events like the recent ones in the Indonesian archipelago can be devastating they are at the smaller end of what the Earth has experienced in the past. Understanding the spectrum of subaqueous landslide processes, and therefore the potential societal impact, requires research across all spatial and temporal scales. This volume delivers a compilation of state-of-the-art papers covering topics from regional landslide databases to advanced techniques for in situ measurements, to numerical modelling of processes and hazards.

Download or read book Deep Marine Systems written by Kevin T. Pickering and published by John Wiley & Sons. This book was released on 2015-10-23 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep-water (below wave base) processes, although generally hidden from view, shape the sedimentary record of more than 65% of the Earth’s surface, including large parts of ancient mountain belts. This book aims to inform advanced-level undergraduate and postgraduate students, and professional Earth scientists with interests in physical oceanography and hydrocarbon exploration and production, about many of the important physical aspects of deep-water (mainly deep-marine) systems. The authors consider transport and deposition in the deep sea, trace-fossil assemblages, and facies stacking patterns as an archive of the underlying controls on deposit architecture (e.g., seismicity, climate change, autocyclicity). Topics include modern and ancient deep-water sedimentary environments, tectonic settings, and how basinal and extra-basinal processes generate the typical characteristics of basin slopes, submarine canyons, contourite mounds and drifts, submarine fans, basin floors and abyssal plains.
