广东阳春石岐顶地区金土壤地球化学异常特征及找矿潜力分析

摘要

根据1∶5万化探Au异常，在石岐顶地区开展1∶1万土壤地球化学测量工作。对获得的761件有效土壤样品进行的Au、Ag、Pb、Zn、Cu、As、W、Sn、Mo、Bi等项目的分析测试表明，石岐顶地球Au异常普遍，尤以十二排一带异常最为明显。结合硅化、黄铁矿化等蚀变岩石样品测试结果，对区内土壤地球化学异常特征进行了分析，结果表明，Au主要富集于NE向断裂带内，石岐顶地区震旦系云开群内断裂带为有潜力的找矿靶区。%According to the 1∶50 000 geochemical anomaly of Au,1∶10 000 geochemical soil survey work was carried out in Shiqiding Region of Yangchun.Au,Ag,Pb,Zn,Cu,As,W,Sn,Mo,Bi etc.were tested from 761 effective soil samples.The result showed that Au anomalies are common in the Region,especially in the twelfth row.Combined with silicification,pyritization and altered rock testing results,the soil geochemical anomaly characteristics were ana-lyzed,the results indicated that Au mainly concentrated in the NE trending fault zone.Sinian Yunkai Group within the fault zone is a potential prospecting target in Yangchun Shiqiding Region.
