摘要: 西南天山地处塔里木板块和伊犁-伊塞克湖板块之间,经历了元古代、早古生代和晚古生代古南天山洋的多次开合,古大陆边缘和沉积盆地构造类型的频繁转换1,在碰撞期及其后构造变形复杂多样,岩浆和变质作用非常强烈,是天山造山带地质构造最复杂的地区之一。在漫长的西南天山造山带的大地构造演化史中,塑造了种类繁多、丰富多彩的矿产资源,尤其中亚南天山地区已成为世人皆知的金、铜、锑、银、锡、汞和非金属矿产的著名远景区。通过西南天山地区矿产资源的综合研究和境内外对比,在合理划分大地构造单元的基础上,对境内西南天山的矿产资源进行综合评价Abstract: South western Tianshan mountains is locaed between Tarimplate and Yili-Yisaihe plate.It underwent splittig and stylolitization of the southern ocean in Proterozoic era,early Paleozoic era and late Paleozoic era and frequent structure type transformation of palaeo-continental edge and sedimentary basin. Tectonic deformation is complex during collision period and afterit. Magmatism and metamorp hism are violent. And it is one of the most complex geological structure in Tianshan orogenic belt. Mineral resource formed in long geological evolution period is rich in South western Tianshan.Especially,South western Tianshan in central Asia has become a famous prospective a rea for its Au,Cu,Ag,Sn,Hg and non-metallic oredeposit. Based on syntheticly studying mineral resource in Tianshan district and correlation our country and neighbours,together with scientific dividing geotectonic units, the autho revaluated mineral resource in Southern Tianshan,China.
