紫金山矿集区铜地球化学块体特征及找矿潜力

运用地球化学块体理论, 在紫金山矿集区1:20万区域化探数据基础上, 利用2 km×2 km窗口数据, 对紫金山矿集区进行了地球化学块体的圈定及内部结构的剖析。分析了铜的地球化学块体各级含量水平所对应的面积、可供金属量、浓集度等参数特征。追索某元素地球化学块体的内部结构, 揭示元素在地球化学块体中逐步浓集成矿的轨迹。对几个重点的Cu的地球化学子块体作了预测评价。指出在这些地球化学块体内还存在巨大的寻找铜矿产资源的潜力。

Copper Geochemical Block Characteristics and Ore Potential of the Zijinshan Ore Concentration Area

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.
