摘　　要：本文通过地质、土壤地球化学及物探相结合的方法,对青海格尔木市水仙南地区基性—超基性岩体的地质特征、成矿特征及找矿前景进行了分析,并将其与邻区夏日哈木富矿岩体(I岩体)特征进行了对比研究。分析结果表明:水仙南岩体区域发育土壤地球化学、磁法、电法异常呈高值段,在异常浓集部位发育镍矿化体,该特征与夏日哈木岩体特征具有一定的相似性。研究认为水仙南岩体具有形成岩浆熔离型镍矿体的潜力。In this paper,the geological characteristics,metallogenic characteristics and prospecting prospects of the basic-ultrabasic rock bodies in Shuixiannan area,Ge ermu city,Qinghai Province are analyzed by means of a combination of geology,soil and geophysical prospecting,and comparing with the characteristics of Xiarihamu ore-rich Rock Body(I rock body)in the adjacent area,which is a magmatic melt-separated type copper-nickel deposit.The analysis results show that south of Shuixian basic-ultrabasic rock mass has a nickel mineralized body in the anomalies of soil,magnetic method and electric method,which is similar to the characteristics of Xiarihamu ore-rich rock body.It is considered that the Shuixiannan basic-ultrabasic rock mass has the potential to form magmatic melt-separated nickel deposit.
