| 摘 要： | 近年来，在东天山地区地质找矿不断取是突破，一系列大型，中型铜金矿床先后被发现。绝大多数铜金矿床在空间上密集分布于黄山－康古尔缝合－剪切带两侧的岛弧带内，时间上集中在石炭纪－二叠纪。金矿床包括造山型，石英脉型和浅成低温热液型，铜矿床包括斑岩型，夕卡岩型和热液脉型及铜镍硫化物型，金，铜和铜镍矿化各自成系统产出，为板块俯冲晚期和碰撞期大规模镁铁质－超镁铁质和中酸性－酸性花岗质岩浆侵位－喷发事件的产物。

| Abstract: | In the past several years, a number of copper, gold and Cu Ag Pb Zn deposits have been discovered and explored in the eastern Tianshan area, Xinjiang. All of the metallic deposits are spatially and densely distributed within the Devonian Late Carboniferous island arc in the north and Carboniferous island arc in the south along the Kangguer Huangshan Carboniferous Permian suture large scale shear zone. These deposits,formed temporally in Carboniferous Permian, can be grouped into gold deposit system comprising epithermal, orogenic and quartz vein types, copper deposit system, porphyry, skarn and hydrothermal vein types, and Cu Ni sulfide system. The three metallogenic systems are genetically associated with the emplacements and eruptions of mafic ultramafic or intermediate felsic magmas during the subduction and extension of post collision of the plates. |
