Workshop 3: Continental Amalgamation and Stabilization of Northeast Asia: Stories before the Stone Age
Information
Eurasia, including the Northeast Asian region, was formed by amalgamation of several continental and micro-continental blocks. For example, convergent plate motion beginning some 320–210 million years ago (Ma) generated the Tongbai-Dabie-Sulu (east–central China) –Imjingang-Gyeonggi (central Korea) –Renge-Suo (Southwestern Japan) –Sikhote-Alin orogen along the paleo-Pacific edge of cratonal Asia. This amalgamated belt reflects collision between the Sino-Korean and Yangtze cratons on the SW portion, and accretion of outboard oceanic arcs with some sialic fragments against the NE margin. Accretion, deformation, and metamorphism of the Himalayan-Tibetan orogenic belt took place during the approximate interval 50–15 Ma, reflecting convergence between the Indian Shield and the nonsubducted Asian lithosphere at about 50–70 Ma. Those two major orogens are characterized by the multiple events involving accretion of outboard oceanic arcs and microcontinental fragments against the Asian lithosphere. In Northeast Asia, the present-day environment of the Earth's surface and biosphere including our human activities are strongly affected by geological and geomorphological characteristics, which were caused by continental amalgamation and stabilization of Northeast Asia before the Stone Age. Specific focus in this workshop includes “lithospheric and crustal evolution and stabilization”. However, this workshop also aims to provide opportunities to link geological sciences to ecology, archeology, and socio-cultural anthropology and to systematize interdisciplinary knowledge on Northeast Asia.
