新疆且末县屈库勒克东金锑矿成矿时代探讨

Discussion on the gold-antimony mineralization age of East Qukulek deposit in Qiemo County,Xinjiang

喀拉米兰晚古生代沟弧带是新疆东昆仑造山带的重要组成部分,近年来取得了一系列金锑的找矿突破,尤其是新疆且末县发现的屈库勒克东金锑矿(大型)更是其中的典型代表。作为该矿的主要评价者,笔者基于近年来对该区地层及时代的研究成果,针对新疆屈库勒克东金锑矿床成矿时代进行了探讨,该矿赋矿地层时代为上石炭统,区内与金锑矿成矿关系密切的闪长玢岩、花岗闪长岩时代为三叠纪,结合该区构造演化史,认为该矿成矿时代可厘定为晚三叠-早侏罗世。

The late Paleozoic gully arc belt of Kalamilan is an important part of the East Kunlun Orogenic Belt in Xinjiang.In recent years,it has made a series of breakthroughs in gold-antimony prospecting,especially in the part in Qiemo County,Xinjiang,which is a typical representative.As the main evaluators of the mine,the author based on the formation of this area in recent years and the research achievements of The Times,in view of the xinjiang QuKu,east gold antimony deposit metallogenic epoch are discussed in this paper,the mine ore to the carboniferous stratigraphic age,closely associated with gold antimony mineralization in the area of diorite porphyrite and granodiorite era as the Triassic,combined with the tectonic evolution,think that the mine metallogenic epoch can be set as the late Triassic to early Jurassic.
