河北正沟银多金属矿地质特征及找矿标志研究

Geological Characteristics and Prospecting Mark of Zhenggou Silver Polymetallic Mine in Hebei Province

正沟银多金属矿位于河北省赤城县,该矿区激电异常呈低阻高极化特征;土壤测量在矿区内圈定多处综合异常,Ag、Pb、Zn、Mo等元素异常规模大,强度高。通过对正沟银多金属矿地质特征进行研究分析,得出该矿找矿前景。研究结果表明:正沟银多金属矿区物、化探异常套合较好,对应地表岩石硅化、黄铁矿化、褐铁矿化、高岭土化等蚀变较强;建立了正沟银多金属矿的找矿标志,经槽探工程、钻探工程验证,矿区内圈定4条银多金属矿体及1条钼矿体,找矿效果良好。

Zhenggou silver polymetallic Mine is located in Chicheng County,Hebei Province.The IP anomaly of Zhenggou silver polymetallic mine is characterized by low resistance and high polarization.The soil survey delineates several comprehensive anomalies in the mining area,also the scale and intensity of Ag,Pb,Zn,Mo and other elements are large.By studying and analyzing the geological characteristics of Zhenggou silver polymetallic deposit,the prospecting prospect of the deposit is concluded.The results show that there is a good combination of minerals and geochemical anomalies in Zhenggou silver polymetallic mine area,and the alteration of surface rocks such as silicification,pyrite,limonite and kaolinization is strong.Based on this,the prospecting mark of the Zhenggou silver polymetallic mine is established.Through the verification of trough exploration engineering and drilling engineering,four silver polymetallic orebodies and one molybdenum ore body are defined in the mining area,and the prospecting effect is good.
