Relationship Between Tectonic Settings and Metallo Genesis of Late Paleozoic-Early Mesozoic Intrusive Rock in Qimantage, Qinghai Province

Orogenic belt mineralization researching is contemporary frontier science.Based on investigating late Paleozoic-early Mesozoic intrusive rocks in Qimantage,North-West of East Kunlun,it is displayed that Qimantage late Paleozoic-early Mesozoic tectonic evolution is similar to that of the East Kunlun.The result shows that Early Permian is ocean basin expanding period.In the period,a great of POG granites are emerged and porphyry copper deposits are formed.Middle Triassic is main diving stage.CAG granites are emerged and skarn polymetalore deposits are brought about in the stage.Late Triassic the ocean basin is closed and post-collision arrived in which POG granites are greatly developed and porphyry molybdenum deposits and skarn polymetalore deposits are found.
