衬值滤波法在哈尔干查拉铜镍矿化探数据处理中的应用

Contrast Filtering Method Applications in Haergan Copper-Nickel Deposit

哈尔干查拉铜镍矿位于新疆和静县东北部,笔者以Surfer系统为平台,运用衬值滤波法对该区Ni元素进行化探数据处理、分析,并将异常结果与传统方法处理结果进行对比。认为相对于传统地球化学数据处理方法而言,衬值滤波法具有客观、方便、高效、能进一步表征地球化学隐藏信息等优点。

Haergan Cu-Ni deposit is located in the northeast of Hejing County, Sinkiang, where it occurs monoclinal strates. The wallrock alteration mainly consists of silicification and carbonatation. Taking Haergan in Xinjiang as the study area and on the platform of Surfer system, the author used contrast filtering method to process and analyze Ni in the region, and the abnormal results are compared with that traditional methods. Relative to conventional method, the contrast filtering method is more convenient, objective, efficient and further characterize hidden geochemical information.
