Abstract

Abstract

Since Regional Geochemistry-National Reconnaissance Program (RGNR) carried out in 1978, the immense amount of geochemical data obtained played a big role in mineral exploration, environmental, ecological and agricultural studies, but its application in geological mapping was quite less. In southern China, granites are widespread and covered by thick intense chemical weathered layers and vegetations, which severely affected the speed and accuracy of geological mapping. Some geochemical maps prepared by using regional geochemical data showed a significant geochemical partition. According to field validation, the chemical zones coincide well with the outcrops of granitic intrusions of different ages. So this can increases the efficiency and accuracy of geological mapping in strongly weathered areas.
