Copper Geochemical Block Characteristics and Ore Potential of the Zijinshan Ore Concentration Area
紫金山矿集区铜地球化学块体特征及找矿潜力

Geochemical block delineation and inner structure analysis were carried out in the Zijinshan ore concentration area by means of geochemical block theory. The work was based on 1:200 000 regional geochemical exploration data, for which 2 km×2 km window data were used. The authors analyzed characteristics of such parameters as area, available metal quantity and concentration degree corresponding to various content levels of the copper geochemical blocks. Probing into the internal structure of the geochemical block of a certain element may reveal the gradual concentration and formation path of that element in the geochemical block. Predictive evaluation was carried out for several key copper geochemical blocks. It is pointed out that there exists great potential in search for copper resources in these geochemical blocks.
