Soil geochemical characteristics and prospecting prediction in Gaoliu area,Xinyi City,Jiangsu Province
Based on the geological characteristics and 1∶10,000 soil geochemical survey in Gaoliu area,Xinyi City,Jiangsu Province,content and combination of elements have been researched systematically and prospecting forecast has been carried through.The results show that the geochemical anomalies of single elements such as Au,Ag,Cu,Mo,Pb,Zn,As and Sn are obvious in this area,among which the anomaly intensity and zonation of Au,Ag and Mo are good,and their morphological distribution is restricted by NNE-trending structural fragmentation and alkali feldspar granite mass.A total of 14 comprehensive anomalies has been identified in the survey area,among which three well-evaluated anomalies are located near the same fault zone with excellent mineralization geological conditions.The geochemical profile verification of the comprehensive anomaly shows that the peaks of Au,Cu and other elements are located in the center of the NNE-trending fault zone.Based on the metallogenic geological conditions and geochemical characteristics of soil,the prospecting criteria of gold and polymetallic deposits in this area are summarized preliminarily,which can provide indirect ba-sis for further prospecting in this area.
