摘要
在甘肃某铅锌矿区存在大范围低阻地层,利用可控源同时具有剖面法和测深法的特点,对隐伏铅锌矿进行了勘查,详细测定并分析了该区岩(矿)石的电性特征,认为低阻及高阻异常并非矿致异常,浅部高、低阻异常的过渡区才是找矿的有利部位。据此布置了钻孔,见矿情况很好。
Largearea low resistivity strata are existent in a certain lead-zinc ore district of Gansu Province. In the application of CSAMT to exploring concealed lead-zinc ore bodies, the authors measured and analyzed in detail electrical characteristics of rocks and ores in this ore district. It is concluded that low resistivity and high resistivity anomalies are not caused by mineralization, whereas the transitional area of the low resistivity anomaly is the favorable area for ore prospecting. Based on such an understanding, the authors arranged drill holes and obtained satisfactory ore-intersecting results.
