The prediction of electrochemical prospecting in Youfang area of the Xiangshan orefield

In order to make a breakthrough in prospecting in the Youfang area of the Xiangshan ore field, the authors carried out geoelectric extraction and surveying in this area for deep prospecting prediction. It is found that the anomalies are obviously controlled by the faults, and are mainly distributed along the ore-controlling faults and the intersection of the faults. Cluster analysis and factor analysis reveal that there is a significant correlation between the trace elements, thus forming the corresponding element combinations: F1 factor (Ti、V、Mo、Th、U), F2 factor (As、Pb、Sb), and F3 factor (Co、Ni). The spatial distribution of uranium-thorium ratios shows a significant positive correlation with the estimated base depth of AMT, controlled by volcanic rock thickness. The authors synthesized the abnormal features of geoelectrically extracted elements and the mineralization regularity of the Xiangshan ore field, established a comprehensive geological-geoelectrochemical prospecting model, and delineated two corresponding targets in the study area, of which No.1 target area has good prospecting prospect.
