Ophiolites in Earth History


Book Description

The 32 papers in this volume examine the mode and nature of igneous, metamorphic, tectonic, sedimentological, and biological processes associated with the evolution of oceanic crust in different tectonic settings in Earth history as revealed in various ophiolites and ophiolite belts around the world, and the geodynamic significance of these ophiolites in the evolution of different orogenic systems. Divided into six thematic sections, the book presents a wealth of new data and syntheses from mainly Phanerozoic ophiolites around the world.




From the Blue Ridge to the Beach


Book Description

Seven chapters explore the diverse geology of Virginia, from its Appalachian highlands to the Atlantic shore.







From Rodinia to Pangea


Book Description

"The Appalachians constitute one of Earth's major tectonic features and have served as a springboard for innovative geologic thought for more than 170 years. This volume contains 36 original papers reporting the results of research performed throughout nearly the entire length and breadth of the Appalachian region, including all major provinces and geographical areas. Memoir 206 was designed to commemorate the (near-)fortieth anniversary of the publication of the classic Studies of Appalachian Geology volumes that appeared just prior to the application of plate tectonic concepts to the region. Contributions concerning structural evolution, sedimentation, stratigraphy, magmatic processes, metamorphism, tectonics, and terrane accretion illustrate the wide range of ongoing research in the area and collectively serve to mark the considerable progress in scientific thought that has occurred during the past four decades."--pub. desc.







Terrane Processes at the Margins of Gondwana


Book Description

The Australide orogen, the southern hemisphere Neoproterozoic to Mesozoic terrane accretionary orogen that forms the palaeo-Pacific margin of Gondwana, is one of the largest and longest-lived orogens on Earth. This book brings together a series of reviews and multidisciplinary research papers that comprehensively cover the Australides from the Tasman orogen of eastern Australia to the Neoproterozoic and Palaeozoic orogens of South America, taking in New Zealand and Antarctica along the way. It deals with the evolution of the southern Gondwana margin, as it grew during a series of terrane accretion episodes from the late Proterozoic through to final fragmentation in mid-Cretaceous times. Global perspectives are given by comparison with the Palaeozoic northern Gondwana margin and documentation of world-wide terrane accretion episodes in the Late Triassic-Early Jurassic and mid-Cretaceous. The Tasmanides of eastern Australia, and the terrane histories of New Zealand and southern South America are given comprehensive up-to-date reviews.




Geology and Landscape Evolution


Book Description

Geology and Landscape Evolution: General Principles Applied to the United States, Second Edition, is an accessible text that balances interdisciplinary theory and applications within the physical geography, geology, geomorphology and climatology of the United States. The vast diversity of terrain and landscape across the United States makes this an ideal tool for geoscientists worldwide who research the country's geological and landscape evolution. The book provides an explanation of how landscape forms, how it evolves and why it looks the way it does. This new edition is fully updated with greater detail throughout and additional figures, maps, drawings and photographs. Rather than limiting the coverage specifically to tectonics or to the origin and evolution of rocks with little regard for the actual landscape beyond general desert, river and glacial features, this book concentrates specifically on the origin of the landscape itself, with specific and exhaustive reference to examples from across the United States. The book begins with a discussion of how rock type and rock structure combine with tectonic activity, climate, isostasy and sea level change to produce landscape and then explores predicting how landscape will evolve. The book goes on to apply those concepts to specific examples throughout the United States, making it a valuable resource for understanding theoretical geological concepts through a practical lens. - Presents the complexities of physical geography, geology, geomorphology and climatology of the United States through an interdisciplinary, highly accessible approach - Offers hundreds of full-color figures, maps and photographs that capture the systematic interaction of land, rock, rivers, glaciers, global wind patterns and climate, including Google Earth images - Provides a thorough assessment of the logic, rationale, and tools required to understand how to interpret landscape and the geological history of the Earth - Features exercises that conclude each chapter, aiding in the retention of key concepts - Updated with greater detail throughout and additional figures, maps, drawings and photographs - Includes additional subheadings so that material is easier to find and digest - Includes an all-new chapter on glaciation and expanded exercises using Google Earth images to enhance understanding




Geology at Every Scale


Book Description

"The chapters in this guidebook are organized according to major geologic themes, starting first with field trips in the Knoxville area that highlight, in some way, local carbonates, and then by ending with field trips focused on regional tectonics that include travel to North and South Carolina and Georgia"--




Processes on the Early Earth


Book Description

"This Special Paper presents a collection of 19 papers contributed to a joint Field Forum organized by the Geological Society of America and the Geological Society of South Africa in July 2004 in the Barberton Greenstone Belt and the Vredefort Dome, South Africa. The papers cover a wide variety of themes, including Archean and Proterozoic crust formation and geodynamics (with an appraisal of evidence of Archean subduction processes); the significance of impacts in the evolution of the early Earth's crust; traces of early life in Archean environments of Australia and South Africa and related studies of depositional environments; and processes affecting the giant Witwatersrand gold deposit."--Publisher's website.
