东天山地区横跨哈萨克斯坦与塔里木两大板块,是新疆最重要的有色金属、黑色金属和贵金属矿产地之一.经历了前震旦纪基底形成→震旦——泥盆纪古亚洲洋形成、消亡→石炭纪→早二叠世后碰撞造山→晚二叠世至今的陆内造山等阶段.主要成矿期为晚古生代早期(泥盆纪——二叠纪),成矿作用复杂、类型繁多.其中,北部形成岛弧斑岩型和火山岩型铜、钼、金矿,中部形成拉张火山岩型和矽卡岩型金、铜、镍、银矿,中南部形成前寒武纪结晶基底叠加改造的层控一热液型铅、锌、银矿,南部库鲁克塔格和北山地区形成拉张铜、镍、金矿通过研究认为,东天山地区尤以铜、镍钼矿产资源潜力很大,优选出28个矿找矿靶区本文主要介绍东天山地区的成矿规律及铜、金矿床的分布.
The eastern Tianshan Mountains span two major plates of Kazakhstan and Tarim, and are one of the most important non-ferrous, ferrous and precious metal mineral deposits in Xinjiang.It experienced the formation of the Sinian basement → Sinian-Devonian Asia sea, Extinction → Carboniferous → post-Early Permian collision orogeny → intracontinental orogeny since Late Permian.The main mineralization period is Early Late Paleozoic (Devonian-Permian) with complicated metallogenesis, type Many of which are island arc-arc porphyry-type and volcanic-type copper, molybdenum and gold in the north, extensional volcanics and skarn-type gold, copper, nickel and silver in the central part, and Precambrian crystalline basement in the south-central part Overlapped layer controls a hydrothermal lead, zinc and silver mine, southern Kuruktag and Beishan area form a pull-out copper, nickel and gold mine Through the study, the East Tianshan area, especially copper, nickel and molybdenum mineral resources potential Large, preferred 28 ore prospecting target This article describes the East Tianshan metallogenic regularity and distribution of copper and gold deposits.
