A New Asian Tectonic Unit Map

Abstract：Based on abundant geological, geochemical and geophysical data of Asian continent, the author compiled a new Asian tectonic unit map, determined the principle of division, and divided Asian continent into six tectonic domains as well as sixty-seven plates (or blocks) and accretion collision zones (or collision zones), and then compiled the tectonic unit map. The plates or blocks of Asian continent were mainly formed at about 1800 Ma, 800 Ma, 500 Ma and 400 Ma,which were the periods to form the unified crystallization basement. There existed quite a few formation periods of collision zones or collision accretion zones, which occurred in 800 Ma, 397 Ma, 345～260 Ma, 200 Ma, 135 Ma, 52 Ma and 23 Ma respectively；in addition, subduction zones have been formed since 23 Ma. With abundant data on geological activities since Paleozoic, this paper discusses roughly the plate migration as well as the formation of intraplate deformation and collision zones during that period. The author has paid special attention to the intraplate deformations of that period, which made many great influences on types, processes and occurrence positions of metallization.
