| 摘 要： | 造山带成矿作用研究是当代成矿学重大研究的前沿,通过对东昆仑造山带北西段祁漫塔格晚古生代—早中生代侵入岩研究,表明祁漫塔格与东昆仑东段晚古生代—早中生代构造演化具有一定相似性。早二叠世之前为洋盆扩张期,早二叠世空谷期洋盆扩张结束,俯冲作用开始,发育钾玄岩系列POG型花岗岩,形成斑岩型铜矿。中三叠世为主俯冲阶段,发育高钾钙碱性大陆弧花岗岩(CAG),形成矽卡岩型铁多金属矿。晚三叠世卡尼—诺利期,大洋闭合,进入后碰撞陆内造山阶段,发育高钾钙碱性钾玄岩系列后造山花岗岩(POG),形成了斑岩钼矿和矽卡岩型铁多金属矿。 |

| Abstract: | 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. |
