智利AF矿区土壤地球化学异常特征及找矿方向

摘要

This paper introduced the soil geochemical anomalies characteristics of AF deposit in Chile.The results showed that SOLE region has geochemical characteristics of porphyry copper deposits.Considering the metallogenic belt in which the deposit locate and the geology characteristics,the genetic types of deposit is thought to be porphyry type in this area.Geophys-ical survey and drilling are proposed to get the mineralization information of the depth in SOLE region ,and then to j udge the genetic types of the deposit and the exploration prospecting more clearly.%介绍了智利AF矿区的土壤地球化学异常特征，结果显示在SOLE 地区具有斑岩型铜矿的地球化学特征，槽探揭露显示铜矿化较好。结合矿区所处的成矿带位置及地质特征，分析认为AF矿区具有寻找斑岩型铜矿的前景。建议下一步在SOLE 地区开展物探和钻探工作，对深部矿化情况进行了解、验证，以对矿床成因类型、找矿前景做出进一步判断。
