近几年来,在某矿区进行了大量次生晕工作,除以铜为指示元素直接找铜矿外,还利用镍指示元素找镍矿。此外,还选用其它元素,结果除工业矿体能产生次生晕外,浸染状矿化带、基性、超基性岩体和片麻岩中分散的黄铁矿化,均能引起不同程度的异常。因此,仅利用其含量级来分辨矿与非矿异常是困难 In recent years, a large number of secondary halo work in a mining area, in addition to copper as a direct element to find copper ore, but also to use nickel element to find nickel ore. In addition, other elements were selected. As a result, in addition to the secondary halo generated by industrial orebodies, pyrite mineralization in disseminated mineralized zones, basaltic, ultrabasic rocks and gneisses can cause varying degrees Abnormal. Therefore, it is difficult to distinguish between mine and non-mine anomaly only by its content level
