Experiment And Application Of The Geochemical Data Processing Methods In Zhongtiaoshan Area, Shanxi

Exploration geochemistry mainly focuses on such fields as the complex geological bodies and its rock types, structural features, iatrogenic geological environments etc., which makes the spot of geochemical anomaly an important factor, which in turn leads to geological prospecting。In our country Zhongtiaoshan area is an important Copper Deposits where about twenty Copper Deposits in different scales have been explored. Consequently, Zhongtiaoshan Industry Company of Nonferrous Metals, as one of the five national Copper industry bases, has been founded and plays a role in the supply system of copper resources.This study, by applying the traditional geochemical data processing, content-totality fractural method and the sub region medina contrast filtering method, spots the anomaly area with copper element by processing the geochemical data of cooper and gold, making some comparisons and selecting, which provides the evidence for the further exploration.The anomaly thresholds of Cu based on the traditional geochemical data processing is similar to that based on the content-totality fractural processing. And the anomaly zones are similar in forms, size and density and comparatively consistent with the current mineral distributing area, which implies a promising future for deposits. The sub region medina contrast filtering method can avoid the influence of geology background. The result has proved that this method can avoid the large anomaly area and also intensify the anomaly area which is located in low geology background.The contrast comparison of the above three methods show that the traditional processing and the fractural processing are fit for the exploration of deposits. By combining the lower anomalies gained by the filtering method, this study selects six anomalies of I and four anomalies ofⅡ, which provide the supportive data for the further deposit exploration.
