摘要
The study on supergene activity discipline of elements is precedent and basic for establishing method and technology of geochemical exploration. The supergene activities of elements from parent rocks and soils in Huitongshan copper mine of the Beishan region are studied, which includes the variation of elements’ contents and hereditability between soils and rocks. It can be concluded that some trace elements as Cu, Mo, Pb, Zn, Au, Ag, As, Bi, Ba and Sr show distinctive enrichment characteristics in soils derived from different rocks. In addition, the analysis of mineral composition of soils indicates there is a positive correlation between elements’ supergene enrichment and the contents of clay minerals, however, a negative correlation between elements’ supergene enrichment and the contents of major rock-forming minerals. According to conclusions above, positive and negative geochemical anomalies are determined with sampling media from -4 to +40 meshes, in Huitongshan copper ore district.
