Relative Role of Eustasy, Climate, and Tectonism in Continental Rocks


Book Description

Papers in this title offer understanding of allocyclic controls on non-marine stratigraphy, allowing better predictions about the nature and geometry of strata within areas of basins where data are more limited. Thus one can better estimate the potential for oil, gas, coal, or mineral accumulations. Authors examine the relative importance of eustasy, climate, and sedimentation supply in determining the nature of lithologies and the packaging of continental strata.







Large Rivers


Book Description

An updated treatment of management and geomorphology of large rivers around the world The newly revised Second Edition of Large Rivers: Geomorphology and Management delivers a thoroughly updated exploration of the form and function of major rivers. The book brings together a set of papers on the large rivers of the world, offering readers an insightful examination of a demanding subject. The new Second Edition of the book includes fully updated and revised chapters, as well as two entirely new chapters on the Ayeyarwady and the Arctic rivers. This fascinating volume describes the environmental requirements for creating and maintaining a major river system, case studies on over a dozen large rivers from different continents in a variety of physical environments, and the measurement and management of large rivers. Unmatched in scope, Large Rivers sheds light on a subject lacking in comprehensive study. Readers will benefit from the inclusion of: A thorough introduction to the geology of large river systems, hydrology and discharge, transcontinental moving and storage of sediment, and the greatest floods and largest rivers An exploration of the classification, architecture, and evolution of large-river deltas Discussions of sedimentology and stratigraphy of large river deposits, including their recognition in the ancient record and the distinction from incised valley fills An examination of the effects of tectonism, climate change, and sea-level change on the form and behavior of the modern Amazon river and its floodplain Measurement and management of large rivers The effect of climatic change on large rivers Perfect for postgraduate students and researchers in fluvial geomorphology, hydrology, sedimentary geology, and river management, Large Rivers: Geomorphology and Management will also earn a place in the libraries of engineers and environmental consultants in the private and public sectors working on major rivers around the world.




Rivers and Floodplains


Book Description

Rivers and Floodplains is concerned with the origin, geometry, water flow, sediment transport, erosion and deposition associated with modern alluvial rivers and floodplains, how they vary in time and space, and how this information is used to interpret deposits of ancient rivers and floodplains. There is specific reference to the types and lifestyles of organisms associated with fluvial environments, human interactions with rivers and floodplains, associated environmental and engineering concerns, as well as the economic aspects of fluvial deposits, particularly the modeling of fluvial hydrocarbon reservoirs and aquifers. Methods of studying rivers and floodplains and their deposits are also discussed. Although basic principles are emphasized, many examples are detailed. Particular emphasis is placed on how an understanding of the nature of modern rivers and floodplains is required before any problems concerning rivers and floodplains, past or present, can be addressed rationally. Rivers and Floodplains is designed as a core text for senior undergraduate and graduate students studying modern or ancient fluvial environments, particularly in earth sciences, environmental sciences and physical geography, but also in civil and agricultural engineering. College teachers, researchers, and practising professionals will also find the book an invaluable reference. Presents a process-based approach, which is relevant to modern curricula. Discusses methods of studying rivers and floodplains and their deposits. Provides many detailed examples throughout the text. Emphasises the basic principles of this subject. As the first synthesis of this entire field, it will be a must-have for all students studying modern or ancient fluvial environments. Teachers, researchers and practising professionals will find this an invaluable reference tool. Rivers and Floodplains will also be of interest to geologists, geographers and engineers.




Sediment Cascades


Book Description

Sediment Cascades: An Integrated Approach provides a comprehensive overview that addresses the transport of sediment through the landscape. Suitable for academic researchers, industry practitioners, research students and advanced level undergraduates, seeking detailed knowledge and an up-to-date review of the recent research literature. The emphasis is on contemporary sediment system dynamics with relevance both to landscape management and landform development. Sediment Cascades: An Integrated Approach begins with an explanation of the need for an integrated approach to sediment delivery systems and introduces the main themes of sediment production, delivery, storage and transfer. Further chapters then focus on specific environments from mountains, through floodplains, to estuaries and the continental shelf. Focuses on contemporary sediment system dynamics and current research Covers a sequence of environments from steep mountains to the continental shelf Highlights the continuity of the subject by linking each component area with its adjacent elements

Opening and Closure of the Neuquén Basin in the Southern Andes


Book Description

This book provides an overview of newly gathered material focusing on the opening and closure of The Neuquén Basin. The Neuquén Basin contains the most important hydrocarbon reservoirs in Argentina and therefore is characterized by a profound knowledge of the sedimentation mechanisms and closure times. During the last 10 years a considerable amount of new information has been produced that illustrates a complex evolution that involves more than one synrift stage during its evolution, an aborted sag phase associated with the inception of a first foreland basin in late Early Cretaceous times, two extensional destabilizations in the Late Cretaceous-Paleocene and late Oligocene times and a Neogene magmatic expansion coetaneous to a last mountain building. These processes have produced a polyphasic complex structure that exhumed the rich sedimentary record that characterizes the basin.




Fundamentals of Geomorphology


Book Description

This extensively revised and updated edition continues to present an engaging and comprehensive introduction to the subject, exploring the world s landforms from a broad systems perspective. It reflects on the latest developments in the field and includes new chapters on geomorphic materials and processes, hillslopes and changing landscapes. Fundamentals of Geomorphology is an engaging and comprehensive introduction. Starting with a consideration of the nature of geomorphology and the geomorphic system, geomorphic materials and processes, and the quest of process and historical geomorphologists, it moves on to discuss: structure: landforms resulting from, or influenced by, the endogenic agencies of tectonic and volcanic processes, geological structures and rock types process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind and the sea history: earth surface history, giving a discussion of Quaternary landforms and ancient landforms, including the origin of old plains, relict, exhumed, and stagnant landscape features and evolutionary aspects of landscape change. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, including a colour plate section."
