摘要
和日金矿区属于碎裂蚀变岩型金矿,赋存于斜长花岗岩、砂板岩以及二者的接触带中。经电法勘探,圈出了10处极化率异常。通过对各地质单元电性特征的总结,对异常进行处理、分析,新发现2条金矿脉,推断一条隐伏石英脉型矿脉,认为4、5号矿脉还有一定程度的延伸,为本区进一步的找矿工作指明了方向。结果表明激电法在该区应用效果良好。
The Heri gold ore deposit is of the cataclastic altered rock type,and its ore bodies lie in plagiogranite,sandy slate and their contact zones.Through electrical exploration,ten polarizability anomalies were delineated,and by summarizing the electric characteristics of every geological unit as well as analyzing and processing these anomalies,two gold veins were found and a concealed quartz vein type gold ore body was inferred.It is believed that No.4 and No.5 gold veins have some extension in length.The direction for further geological prospecting in this area is also pointed out.The results show that the IP method is an effective means in this area.
