| 摘 要： | 通过金川南延地电提取法找矿研究发现,Ni、Co的相关系数为0.8,表现出极强正相关性。根据测区的地电化学测量结果（wB）：Ni背景值为1.57×10-6,Co的背景值为0.28×10-6。以w（Ni）〉4.3×10-6、w（Co）〉0.84×10-6划分内带,以w（Ni）（2.9～4.3）×10-6、w（Co）（0.56～0.84）×10-6划为外带,结合该地区的岩体和构造线走向,圈定出3个有找矿潜力的Ni、Co异常带。地电提取法在干旱、岩屑覆盖区找矿具有可行性。

| Abstract: | Geoelectro-chemical extraction method is used to prospect Ni-Co deposit in south Jinchuan area.The correlation between Ni and Co is over 0.8（positive correlation）.Ascertaining the natural value of mineral elements by statistic comparison is Ni 1.57×10-6,Co 0.28×10-6.In order to make the information of icon distinctively,the abnormal area can be divided into high consistency area and light consistency area.High consistency area can be divided by the standard（Ni4.3×10-6,Co0.84×10-6）.Light consistency area can be divided by the grade（Ni 2.9×10-6 to 4.3×10-6,Co 0.56×10-6 to 0.84×10-6）.In the distributing contrast of rock and tectonic alignment,Ni-Co abnormity is found in this area.It is verified that geoelectro-chemical extraction method in the dry and debris covered area is effective indeed. |
