摘要: Based on geochronological data and the regional geological evolution, it is indicated that mineralization processes in eastern Tianshan are characterized by multiple stages. These related to an arc accretionary stage (∼360–320 Ma) with porphyry-type volcanic sediment deposits, a collision-post orogenic (∼300–250 orogen-type deposits magmatic copper-nickel ore intra-continental extension (∼ 250–220 gave rise Jinwuozi gold deposit, Xiaobaishitou W-Mo deposit Baishan Mo-Re deposit.
