摘　　要：运用地球化学块体理论,在贵州省1∶20万区域化探数据基础上,利用10km×10km窗口数据,对贵州省东部进行了地球化学块体的圈定及内部结构的剖析。分析了各成矿元素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,并对集中几个重点的Au、Ag、Pb、Zn的地球化学块体作了预测评价。指出在这些地球化学块体内还存在巨大的寻找金、银、铅、锌矿产资源的潜力。Geochemical block outlining in eastern part of Guizhou and its inner structure analysis was carried out with geochemical block theory on the basis of 1/200000 regional geochemical exploration data of which 10km×10km window data was used. The paper analyzed the characteristics of several parameters including area,available metal quantity and concentration degree corresponding to various content levels of the geochemical blocks of different ore elements.Predictive evaluation was carried out for several key geochemical blocks of Au?Ag?Pb?Zn.It is pointed out that there are great potential to search for gold,silver,lead and zinc mineral resources in these geochemical blocks.
