湖北阳新阮宜湾铜钨钼矿床找矿预测地质模型及找矿前景研究

The Geological Model of Prospecting Prediction and Prospecting Potential of Ruanyiwan Cu-W-Mo Deposit in Yangxin,Hubei

笔者以叶天竺的"勘查区成矿地质体找矿预测理论方法"为指导,对阮宜湾铜钨钼矿床进行深入研究,确定阮宜湾矿床的成矿地质体为阮宜湾石英闪长岩岩株体,成矿构造为黄姑山—犀牛山倒转背斜和阮宜湾断裂带,成矿结构面为石英闪长岩岩体与奥陶系碳酸盐岩的接触带及接触带附近的志留/奥陶系硅钙面,以及成矿作用特征标志,构建找矿预测地质模型,结合物化探资料对阮宜湾矿床深边部开展找矿预测。

Guided by YE Tianzhu＇s metallogenic geological body prospecting prediction theory in prospecting area,we have researched on Ruanyiwan Cu-W-Mo deposit deeply,and determined that the metallogenic geological body is Ruanyiwan quartz diorite stock intrusion;the metallogenic structure is Huanggu Mountain-Xiniu Mountain reversal anticline and Ruanyiwan fault belt;and the metallogenic structural planes are as follow：one is the contact zone between the Ordovician carbonate stratum and the quartz diorite intrusion,and the other is the calcium-silicon interface of Silurian/Ordovician close to the contact zone.As well,we have identified the metallogenic signs,established the geological model of prospecting prediction,proposed a lot prospecting potential areas in the deep and side of Ruanyiwan deposit combined with the geophysical-geochemical data.
