陕西省略阳县陶家沟地区地质地球物理特征及找矿预测

Geophysical Characteristics and Prospecting Prediction of Taojiagou Area in Lueyang County,Shaanxi Province

通过对略阳县陶家沟地区地质地球物理特征分析,认为陶家沟存在一个由磁铁矿化角砾状蛇纹岩组成的角砾岩筒,按照岩浆熔离成矿理论,应用地质地球物理综合预测方法,预测在角砾岩筒底部、正负磁异常转换部位及电法异常梯度带附近是铜金矿成矿的有利部位。

Through the analysis of the geophysical characteristics,this paper believes that in Taojiagou area of Lüeyang County there is a breccia pipe composed of magnetite mineralized brecciate serpentinite.Based on the theory of magmatic separation mineralization,the authors predicted that the favorable place for copper-gold ore-forming was the conversion parts of the positive-negative magnetic anomalies and near the electrical anormaly gradient zone at the bottom of the Breccia pipe.
