中文摘要:
      矿床位于西昆仑—喀喇昆仑构造带上的塔什库尔干地区,是新疆西南部著名的“帕米尔式”铁矿产地。近年来随着基础地质工作的深入开展,铜金多金属矿产勘查也取得了突出的成果。为了进一步研究矿床成因并指导找矿,文章结合区域成矿地质背景,以塔什库尔干铜金多金属地质勘查成果为依据,通过深入分析有利的成矿地质条件,认为其赋矿围岩为古元古界布伦阔勒群老变质岩系和侵位于喜山期碱性杂岩中的隐爆角砾岩体,矿体受北西向逆冲推覆构造控制。矿化与喜山期花岗斑岩和角闪正长岩关系较紧密,矿床类型以构造蚀变岩型铜金矿、引爆角砾岩型铜金矿、热液脉型铅钼矿为主。绢英岩化和萤石化是该区最有利的找矿标志。综合研究认为该区具有良好的铜、金、铁、铅锌多金属成矿潜力。
英文摘要:
      The deposit is located in Taxkorgan area of the west kunlun-Karakorum tectonic belt, which is a famous place for Pamir-style iron deposit in southwest of Xinjiang. In recent years, as the basic geological work goes further, many outstanding outcomes in exploration of copper-gold-polymetallic have been achieved. In order to study further orebody genesis and guide ore prospecting, this research work considers regional geological background, on the basis of the copper-gold-polymetallic minerals exploration results, and through deep analysis of favorable geological metallogenetic conditions, then it is agreed that the Lower Proterozoic Buren Le broad group of old metamorphic rocks and breccia in alkalic complex that was emplaced in the Himalayan are the ore-host rock, and it is studied that mine controlling structure styles of the NW trust nappe tectonic. Copper-gold mineralization is closely related to the Himalayan stage granite porphyry and hornblende syenite, Mineralization is mainly in phyllic alteration copper-gold deposits, detonating breccia copper-gold deposits, epithermal vein led-molybdenum polymetallic deposits. Sericite-quartz alteration and fluoritization is the most favourable indicator for deposit. The result of comprehensive evaluation shows that this district has great potential in copper-gold-iron-lead-zinc polymetallic mineralization.
