The Mesozoic Granitoid Magmatism and Metallogeny of the Central Asian and Pacific Belts Junction Area

摘要

Materials pertaining to Mesozoic granitoids in the Central Asian and Pacific Belts junction area andthe adjacent platforms are summarized. Maps of the location of massifs, the extensiveness of granitoid magma-tism, the manifestations of Mesozoic plumes, and the relief of the asthenosphere surface have been compiled.The locations of the major ore deposits are plotted on the maps. The distribution chart has been constructed forthese deposits in the coordinates of the crust and lithosphere. The depth of the occurrence of the sources forlarge and superlarge gold, tin, polymetallic, molybdenum, tungsten, and uranium deposits has been estimated.Areas showing promise for the discovery of large deposits are defined.
