Tanayama Terrace: Second Edition: Geological, Geophysical, and Tectonic Perspectives on Arc-Arc Collision

Active plate margins display remarkable geological diversity, reflecting complex tectonic processes. Among them, arc-arc collisions have profound effects on long-term environmental change and the redistribution of mass at Earth's surface.This book unravels the tectonic history of an arc-arc collision front by integrating field geology with modern geophysical methods. Stratigraphy, sedimentology, and structural geology are combined with gravity-anomaly analysis and numerical modeling to reconstruct the spatial and temporal evolution of tectonic events and reveal the three-dimensional structure of sedimentary basins.The authors present a case study of the Tanayama Formation, a Plio-Pleistocene event-sedimentary unit preserved on an uplifted river terrace within the intense Quaternary collision zone between the southwestern and northeastern Japan arcs. By integrating evidence from surface processes with insights into the deep subsurface, this multidisciplinary study offers a new perspective on the evolution of active collision zones.The book will be valuable to geological survey professionals, researchers, university faculty, and graduate and undergraduate students.
