根据东天山金铜矿带不同单元按构造 -岩石地层划分原则 ,石炭系分出有序和无序两套地层岩石组合和生物组合 ,两个构造 -火山活动带和两个古陆边缘成矿系统。碰撞造山与韧性剪切带强时空耦合 ,岛弧火山岩成带分布 ,杂砂岩形成于塔里木陆缘岛弧边缘 ,碰撞花岗岩呈中小型东西成带分布 ,地球化学分省分区。构造演化呈多阶段 (分 12个阶段 ) ,碰撞造山细分 3阶段 6期 ,金铜成矿时代以海西中晚期 ( 2 90~ 2 30Ma)为主 ,不同古陆边缘成矿系统其成矿类型、特征等均不相同 ,指明了金铜找矿方向
According to the principles of tectono-lithostratigraphic division in different units of the East Tianshan Gold-Copper belt, the Carboniferous separates two sets of stratigraphic rock assemblages and bio-assemblages and two tectono-volcanic activity zones and two ancient continental margin mineralizations system. The collisional orogeny and the ductile shear zone are strongly coupled in time and space, and the arc arc volcanic rocks are distributed in the belt. The miscellaneous sandstone is formed on the arc edge of the Tarim Island marginal island. The collisional granites are distributed in small and medium scale, with geochemical subdivision. The tectonic evolution is multi-stage (12 stages) and collisional orogenic subdivision stage 3, stage 6. The gold-copper mineralization age is mainly in the middle and late Hercynian (290 to 230 Ma), with different age-related continental margin mineralization systems The types and characteristics of the ore are all different, indicating the prospecting direction of gold and copper
