摘要
通过对研究区 10 818个土壤地球化学数据的处理 ,获得了Au ,Ag等值线图、异常图及不同元素间的比值图。Au高值分布于叶家小湾 -擂鼓台一带 ;Ag高值分布于陈家寨 -擂鼓台一带。Au异常主要受岩浆岩和NE向断裂控制 ;Ag异常主要受SN向断裂带控制 ,且分布于研究区东部。地球化学特征表明 ,擂鼓台 -叶家小湾一带具有良好的银矿、金矿找矿前景。
Calculation of 10818 soil geochemical data and relative maps shows that of soil geochemistry in Hongshi area, equal value line and anomaly maps of Au,Ag elements and figures of ratio between elements are obtained. Higher value of gold anomalies controlled by magmatic rocks and NE striking faults and lie in Yejia xiaowan Leigutai area; and silver anomalies locate in the eastern part of the area along Chengjiazhai Leigutai area and are controlled by the SN striking faults. Gold anomalies were mainly controlled by magmatic rocks and NE fault. Geochemical characteristics indicates that the Leigutai Yejiaxiaowan area is potential for prospecting of silver and gold deposits.
