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.
