摘    要:利用综合对比研究与实际野外工作,获得的秦祁昆造山带重要成矿事件与构造响应的研究及地质找矿信息。通过金川矿床所在的龙首山群与南祁连化隆微地块中的化隆群结晶基底的地质对比,结合地球物理及其相关其他地质信息,发现化隆群具有与金川矿床所在的龙首山隆起相似的成矿地质条件。由此,提出南祁连化隆微地块具有较好的铜镍成矿条件及找矿潜力,所发育的铜镍矿点与金川矿床可能为同一大规模岩浆构造作用的产物。现有的野外工作及找矿实践亦表明了在巨厚红层覆盖下发育基性超基性岩体,并表现出铜镍矿化显示,同时提示在化隆微地块还有发现新的同类型岩体和铜镍矿床的潜在条件。

关 键 词:南祁连,化隆,铜镍矿,地质条件,找矿方向

Abstract:The prospecting information and research results of response between important metallogenic events and structures in Qinling,Qilian and Kunlun Mountains are obtained by the comprehensive contrasting and actural field work. The geological comparison of crystalline basement between Longshoushan group and Hualong group, its geophysics and other geological information,showing the metallogenic geological conditions of Hualong micro-massif is similar with the Longshoushan uplift, in which occurs the giant Jinchuan Ni-Cu deposit. Therefore, it suggests that Hualong has good metallogenic condition of Ni-Cu and prospecting potentiality,and the Ni-Cu ore deposits in Hualong micro-massif and the giant Jinchuan Ni-Cu deposit are the results of the same large tectonic magmatism. It proved that bearing basic-ultrabasic intrusive rocks and mineralization under thick red cover by field work,and there are potentials for finding new rock masses and Ni-Cu deposits of the same type.
Keywords:south Qilian mountain  Hualong  Ni-Cu deposit  metallogenic geological conditions  prospecting direction
