新疆黄山-镜儿泉铜镍成矿带典型矿床特征及成因分析

黄山-镜儿泉铜镍成矿带是我国重要的大型铜镍矿基地。岩体为洋内俯冲的增生岛弧环境产物，为北天山洋壳向北俯冲增生记录。上地幔物质形成岩浆后，在弧间相对稳定的构遣环境下得以发生充分的岩浆重力分异，随着断裂构造的多期活动，这些岩浆、含硫化物岩浆和矿浆分别沿断裂被挤压-侵入上部地壳，形成基性-超基性岩的复式杂岩体和复式矿床，从而构成有特色的硫化铜镍矿床。成岩成矿时间应该在280～510Ma之间。

Typical deposit Characteristics and Genetic Analysis of Huangshan-Jing'erquan nickel-copper metallogenic belt in Hami of Xinjiang

The Huangshan-Jing＇erquan nickel-copper metallogenic belt is our country important large-scale copper-nickel ore base.Rock mass proliferation arc-shaped archipelago environment product which dives for the ocean in,dives the proliferation record for the northern Tianshan ocean shell to the north.After the upper mantle material forms the rock magma, under the relatively stable structural environment can have the full rock magma gravitational differentiation in the arc between.Along with the faulted structure multi-time activity,these rock magma,are extruded separately including the sulfide rock magma and the pulp along the break - upside the invasion the earth＇s crust, forms the basic-ultrabasic rock the multiple mixed rock mass and the multiple ore deposit,thus constitutes has the characteristic cupric sulfide nickel ore deposit.the crag mineralization time is supposed between 280 - 510Ma.
