The Tectonics And Metallogenesis Of Asia

The purpose of this book is to provide a review of tectonic outlines of the Asian continent, metallogenesis rules of 242 large deposits or fields in 67 tectonic units of 6 tectonic domains in the Asia, and guidelines for the mining companies to effectively prospect the large deposits in the Asia in future. The main contents include the tectonic evolution of every tectonic unit in Asia at different geological periods, the mechanism of growth and intraplate deformation of the Asian continental lithosphere, the lithospheric types of the Asian continent, and relationship between tectonic evolution and mineralization process in the Asian continent.

"The major purpose of this volume is to provide a comprehensive synthesis of the regional geology, tectonics, and metallogenesis of Northeast Asia for readers who are unfamiliar with the region and for researchers who desire detailed information on the region. The major parts of the volume are (1) an introductory chapter; (2) a chapter on methodology of regional metallogenic and tectonic analysis; (3) a chapter on mineral deposit models for the region; (4) five chapters that describe the regional metallogenesis and tectonics of the region from the Archean through the Present for successive time stages; (5) a chapter on a metallogenic and tectonic model for the region; and (6) three appendixes, including on a description of the project and products, a description of map units for the Northeast Asia geodynamics map, and a summary table of metallogenic belts for the region. An important goal of the volume is to demonstrate how a high-quality metallogenic and tectonic analysis, including construction of an associated metallogenic-tectonic model, greatly benefits other mineral resource studies by (1) synthesizing of mineral-deposit models, (2) improving prediction of undiscovered mineral deposits as part of quantitative mineral-resource-assessment studies, (3) assisting land-use and mineral-exploration planning, (4) improving knowledge of regional geology; (5) improving interpretations of the origins of host rocks, mineral deposits, and metallogenic belts, and (6) suggesting new research. Research on the metallogenesis and tectonics of such major regions as Northeast Asia requires a complex methodology including (1) definitions of key terms, (2) compilation of a regional geologic base map that can be interpreted according to modern tectonic concepts and definitions, (3) compilation of a mineral-deposit database that enables a determination of mineral-deposit models and clarification of the relations of deposits to host rocks and tectonic origins, (4) synthesis of a series of mineral-deposit models that characterize the known mineral deposits and inferred undiscovered deposits in the region, (5) compilation of a series of metallogenic-belt belts constructed on the regional geologic base map, and (6) construction of a unified metallogenic and tectonic model. The Northeast Asia study area consists of eastern Russia (most of eastern Siberia and the Russian Far East), Mongolia, northern China, South Korea, Japan, and adjacent offshore areas. Major cooperative agencies are the Russian Academy of Sciences; the Academy of Sciences of the Sakha Republic (Yakutia); VNIIOkeangeologia and Ministry of Natural Resources of the Russian Federation; the Mongolian Academy of Sciences; the Mongolian University of Science and Technology; the Mongolian National University; Jilin University, Changchun, People's Republic of China; the China Geological Survey; the Korea Institute of Geosciences and Mineral Resources; the Geological Survey of Japan/AIST; the University of Texas, Arlington; and the U.S. Geological Survey (USGS). This study builds on and extends the data and interpretations from a previous project on the Major Mineral Deposits, Metallogenesis, and Tectonics of the Russian Far East, Alaska, and the Canadian Cordillera conducted by the USGS, the Russian Academy of Sciences, the Alaska Division of Geological and Geophysical Surveys, and the Geological Survey of Canada. The major products of the Northeast Asia project are described in appendix A."--Executive summary.

The evolution of Asia has largely occurred over the last 400 million years, and continues today. Seeing a continent in the act of assembly provides a rare opportunity to study the processes by which continents are constructed and internally modified. This book is a collection of twenty-one contributions on the tectonic evolution of Asia. The book is divided into five parts: geodynamic models of the Cenozoic deformation in Asia, seismotectonics, geological evolution of the Himalaya–Karakoram Ranges, tectonics of the Cenozoic Indo–Asia collision, and Mesozoic–Paleozoic assembly of Asia. Several important problems are addressed in detail, including the origin of the Tibetan Plateau, the nature of ultra-high pressure metamorphism in east-central Asia, the accretion of microcontinents to Asia, and the accommodation mechanisms of the Indo-Asian collision. The Tectonic Evolution of Asia provides an authoritative description of our current understanding of Asian tectonics and continental growth for graduate students and researchers.

Contains publications compiled in 1997 and 1998 on mineral resource data files, articles on mineral deposits models, metallogenesis, regional tectonics, and tectonic map explanations; with color regional tectonic maps and figures.

The book provides the results of tectonic, geological and geophysical studies of Northern, Central and Eastern Asia obtained over the last 20 years, and a Tectonic map for this area overview as well as essays on its geodynamic evolution. These new results were obtained by an international team of specialists within the project “Atlas of geological maps of Central Asia and adjacent areas,” scale 1: 2,500,000, initiated in 2003 by geological surveys of Russia, China, Mongolia, Kazakhstan and South Korea under the auspices of the CGMW. The most of the book contains the descriptions of the tectonic structure of major geological regions of Asia, such as the Ural, Sayan-Baikal and Tien Shan orogenic systems. The tectonic structure of the Pamirs, Turan Plate, Mongolia, Southern China, Korea and other regions is also discussed. The book contains maps of gravity and magnetic anomalies, sketch maps of deep structures of the area, and the geotransect crossing the most important geological structures of Asia. The final chapter of the book describes the tectonic evolution of the Central Asian Orogenic Belt from the Neoproterozoic to the Mesozoic.
