摘要
In the Xiding Au orefield of Bulang,it is hot,rainy and covered with wide area of forest. The rocks are weathered intensively by the chemical agent. The soil bed is very developed. And the bed rock outcrop is very rare, which results in the difficulties in the exploration of mineral resources. In order to search for the effective geochemical exploration method of mineral resources in the tropical rainforest, the authors carried out the experiments of sampling density, sampling bed(soil), sampling medium, sample processing grain size, analysis method and geochemical section of soil, etc., and research of the distribution of geochemical elements in the upper soil of ore body and dead area, which can provide the foundation of sampling density, sampling material, sampling bed(soil), sample processing scheme, sample analysis, anomaly examination, etc.,for the future exploration of nonferrous mineral resources in tropical rainforest area.
