中文摘要: 在秧田沟铜镍矿床详查工作基础上,根据大量地质信息对该矿床地质特征进行了分析总结并提出找矿标志。认为该矿床属岩浆溶离型Cu-Ni硫化物矿床,与基性与超基性岩体的侵入有关,由岩浆的熔离作用沿张性断裂贯入而成。岩体的主要矿物成分为橄榄石、辉石等,主要蚀变作用有绢云母化、绿帘石化及蛇纹石化、绿泥石化等。围岩蚀变产生的矿化对找矿具有指导性的意义。
Abstract:The geological characteristics and prospecting indicator of the Yangtiangou copper-nickel deposit were analyzed and summarized according to abundant. geological information. It shows that the deposit belongs to the magmatic liquation Cu-Ni-sulfide deposit which relates to the basic-ultrabasic intrusion and it is formed by the injection of magma along the extension fracture on the effect of liquid immiscibility. The main mineral compositions of the rockmass are olivine and pyroxene etc., and the alterations are sericitization, epidotization and serpentinization, chloritization etc. The mineralization generated by wall rock alteration has the guiding sense for prospecting.
