Available in PDF, EPUB and Kindle. Book excerpt: Mass Transport, Gravity Flows, and Bottom Currents: Downslope and Alongslope Processes and Deposits focuses solely on important downslope and alongslope processes. The book provides clear definitions and characteristics based on soil mechanics, fluid mechanics and sediment concentration by volume. It addresses Slides, Slumps, and Debris Flows, Grain Flows, Liquefied/Fluidized Flows, and Turbidity Currents, Density plumes, Hyperpycnal Flows, the Triggering Mechanisms of Downslope Processes, Bottom Currents, and Soft-Sediment Deformation Structures. The mechanics of each process are described in detail and used to provide empirically-driven categories to help recognize these deposits it the rock record. Case studies clearly illustrate of the problems inherent in recognizing these processes in the rock record, and potential solutions are provided alongside future avenues of research. An appendix also provides step-by-step guidance in describing and interpreting sediments. - Comprehensively addresses modern downslope and alongslope processes, including definitions and mechanisms - Provides key criteria for the recognition of depositional facies in the rock record - Includes case studies to illustrate each downslope and alongslope process - Identifies key problems and potential solutions for future research - Uses pragmatic, empirical, data-driven interpretations to revise conventional facies models

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 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep-water (below wave base) processes, although generallyhidden from view, shape the sedimentary record of more than 65% ofthe Earth’s surface, including large parts of ancientmountain belts. This book aims to inform advanced-levelundergraduate and postgraduate students, and professional Earthscientists with interests in physical oceanography and hydrocarbonexploration and production, about many of the important physicalaspects of deep-water (mainly deep-marine) systems. The authorsconsider transport and deposition in the deep sea, trace-fossilassemblages, and facies stacking patterns as an archive of theunderlying controls on deposit architecture (e.g., seismicity,climate change, autocyclicity). Topics include modern and ancientdeep-water sedimentary environments, tectonic settings, and howbasinal and extra-basinal processes generate the typicalcharacteristics of basin slopes, submarine canyons, contouritemounds and drifts, submarine fans, basin floors and abyssalplains.

Available in PDF, EPUB and Kindle. Book excerpt: Landslides have geological causes but can be triggered by natural processes (rainfall, snowmelt, erosion and earthquakes) or by human actions such as agriculture and construction. Research aimed at better understanding slope stability and failure has accelerated in recent years, accompanied by basic field research and numerical modeling of slope failure processes, mechanisms of debris movement, and landslide causes and triggers. Written by seventy-five world-leading researchers and practitioners, this book provides a state-of-the-art summary of landslide science. It features both field geology and engineering approaches, as well as modeling of slope failure and run-out using a variety of numerical codes. It is illustrated with international case studies integrating geological, geotechnical and remote sensing studies, and includes recent slope investigations in North America, Europe and Asia. This is an essential reference for researchers and graduate students in geomorphology, engineering geology, geotechnical engineering and geophysics, as well as professionals in natural hazard analysis.

Download or read book Unlocking the Stratigraphical Record written by Peter Doyle and published by John Wiley & Sons. This book was released on 1998-03-06 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stratigraphy is the key to understanding the geological evolution of the earth. It provides the framework for our interpretation of the sequences of events which have shaped the earth throughout its 4600 million years of existence. It provides the timescale with which we can determine the relative order of these events, and it provides the means whereby we can calibrate this using absolute ages in years. Stratigraphy is therefore the most fundamental subject in the science of geology, and all geologists are practising stratigraphers. Traditionally, however, stratigraphy has been considered as a Victorian science, a ponderous process of the naming and cataloguing of innumerable geological units most of which are of limited interest outside of a given geographical region. This view has been challenged in recent years through the development of new techniques such as sequence stratigraphy, cyclostratigraphy and chemostratigraphy which have greatly enhanced our capability to interpret earth history. In this book many of the leading practitioners of modern stratigraphy have been gathered together to provide up-to-date and authoritative reviews of most of the important advances in the subject. As such it is the only volume to provide a comprehensive treatment of modern stratigraphy at an advanced undergraduate level.
Download or read book New Perspectives on Deep water Sandstones written by G. Shanmugam and published by Elsevier. This book was released on 2012-01-25 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is vital for understanding the origin of deep-water sandstones, emphasizing sandy-mass transport deposits (SMTDs) and bottom-current reworked sands (BCRSs) in petroleum reservoirs. This cutting-edge perspective, a pragmatic alternative to the conventional turbidite concepts, is crucial because the turbidite paradigm is built on a dubious foundation without empirical data on sandy turbidity currents in modern oceans. In the absence of evidence for sandy turbidity currents in natural environments, elegant theoretical models and experimental observations of turbidity currents are irrelevant substitutes for explaining the origin of sandy deposits as "turbidites." In documenting modern and ancient SMTDs (sandy slides, sandy slumps, and sandy debrites) and BCRSs (deposits of thermohaline [contour] currents, wind-driven currents, and tidal currents), the author describes and interprets core and outcrop (1:20 to 1:50 scale) from 35 case studies worldwide (which include 32 petroleum reservoirs), totaling more than 10,000 m in cumulative thickness, carried out during the past 36 years (1974-2010). The book dispels myths about the importance of sea level lowstand and provides much-needed clarity on the triggering of sediment failures by earthquakes, meteorite impacts, tsunamis, and cyclones with implications for the distribution of deep-water sandstone petroleum reservoirs. - Promotes pragmatic interpretation of deep-water sands using alternative possibilities - Validates the economic importance of SMTDs and BCRS in deep-water exploration and production - Rich in empirical data and timely new perspectives
Download or read book Environmental Change in Iceland Past and Present written by J. Maizels and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: 3 new biota and extinction of others, and extensive soil erosion reaching almost catastrophic proportions have led to desertification of many upland areas and abandonment by local populations. The role of climatic change as opposed to deforestation and sheep grazing in creating these new environments has proved a further issue of great controversy. While our understanding of historic environmental changes remains inadequate, our knowledge of processes that are modifying the present-day landscape is also sparse and selective. Little is known of active periglacial processes, slope instabilities, and rates of soil erosion by slope wash and aeolian transport. Coastal processes of erosion and beach formation have been studied only locally. Most of our information on recent or active processes comprises records of glacier fluctuations, volcanic eruptions and jOkulhlaup events, but sti11little is known of the mechanisms and processes of landscape change effected by these events. This volume of papers, based on a conference sponsored by the Quaternary Research Association and the Geologists Association and held at the University of Aberdeen in April 1989, addresses many of these crucial uncertainties regarding environmental changes in Iceland from the Lateglacial onwards. The papers make a major contribution to dispelling many earlier uncertainties and clarifying areas of controversy. Many of the papers challenge traditional and poorly supported ideas, replacing them with hypotheses based on new data and new insights derived from the expansion of wider scientific expertise and theory. The volume focuses on three major areas of research in particular.
