洮南市聚宝铜矿地质特征及矿床成因分析

摘要

指出了吉林省洮南市聚宝铜矿位于布敦花-长春岭构造成矿带上,矿区发现了3个近南北向展布呈雁行排列的矿脉组,蚀变闪长玢岩及近南北向断裂控制铜矿的产出与分布.矿石矿物除铜外还伴生金、银,有利于金属矿物的综合利用.通过综合研究,确定了该矿床成因属于中温热液矿床,成矿与闪长玢岩关系密切,成矿特征可与斑岩型矿床相类比.%The Jubao copper deposit is situated at the Budunhua-Changchunling tectonic-metallogenic belt.The deposit is made up with 3 nearly SN lode groups which is distributed in en echelon arrangement.Altered diorite porphyrite and SN fracture control the growth and distribution of copper.The main ore mineral is copper, accompanying gold and silver mineral which are helpful for the comprehensive utilization of mineral resources.It is concluded that the deposit belongs to medium temperature hydrothermal deposit.The diorite porphyrite has close relationship with mineralization, and the metallogenic characteristics can contrast with porphyry deposit.
