Abstract: In order to further understand the effect of using geo-electro-chemical integration technology on finding concealed uranium deposits,to find the prospecting technical indicators of hidden uranium deposits in Changtai-Jiangshan area of Zhejiang,to solve the problems in similar deep prospecting areas, the authors carried out the research on ore prospecting based on geo-electro-chemical extraction method, aided by soil ion conductivity and soil heat-release mercury (Hg).Through the R-type cluster analysis and R-type factor analysis based on the extracting of nine elements such as U, Th, Pb, Zn, Cu, Ag, Mo, V and W by geo-electric method, the results indicate that Th, Pb, Zn, Mo and Ag are most closely related to main ore-forming element U, which can be used as reference index for finding similar concealed uranium deposits. The distribution characteristics of geo-electro-chemical anomalies reveal that the fault structure and contact zone are mainly ore-controlling factors in this area. According to geo-electro-chemical extraction of single element anomalies plane characteristics, abnormal distribution of factor score,synthesize soil ion conductivity,abnormal spatial distribution characteristics of soil heat-release mercury, combined with the geology conditions in study area,the authors delineate seven ore prospective areas in the research area. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
