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-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.

East Tianshan Mountains cross Kazakhstan plate and Tarim plate; it is the most important non-ferrous metals,.precious metals and ferrous metal ores of Xinjiang.It has gone through the basement before Sinian formed → Sinian-Devonian formation and vanishment of ancient Asian Ocean →Carboniferous →the Early Permian after the collision orogeny → Late Permian has made the land within the mountain stages.The main mineralization is the early Late Paleozoic (Devonian-Permian),mineralization complex and variety."The north formed island are volcanic and porphyry-type copper,molybdenum,gold; the middle formed Tensile volcanic type and skarn-type of gold,copper,nickel,silver; the middle south part formed Layer control-hydrothermal type of lead,zinc,silver which transformed in Precambrian crystalline basement.Kuruketage and northern areas in the north of East Tianshan Mountains formed Tensile copper,nickel,gold.Through the study,mineral resources of East Tianshan especially copper,nickel molybdenum have great potential,selected 28 ore prospecting targets.This thesis describes the Metallogenie characteristics of east Tianshan Mountains and the distribution of copper and gold deposit.
