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 280～310Ma.
