| [摘要]应用高密度电法对巴彦查干金矿区的玉号矿化带进行勘探,电阻率异常反映出测区由上
至下为穹窿层状地层-早期岩体-晚期侵入体三元结构,并且得到了钻探工程证实。两种岩体接触带及
次断裂带呈现低阻特征。浅部的充电率异常范围和强度小,且多与已知矿脉对应,深部异常范围和强度
大,且平面投影位置多处在矿化带边部。两种异常的组合特征反映出矿化受低阻断裂和岩体两种因素
控制,矿化具有分带现象。 |

| Abstract:Prospecting was carried out at the mineralized zone No郾1 in the Bayanchagan gold deposit with the high-density electrical method郾Meas鄄
ured resistivity abnormities show the survey area is characterized by a three-element structure consisting of dome strata,early rocks and late intrusions from
upper to lower,which is proved by the drilling郾The contact zone between two rocks and subsidiary faults show a low-resistivity character. The shallow
chargeability anomalies are small in both range and intensity,and consistent with the known lodes郾The deep chargeability anomalies are large in area and
high in intensity,of which many ground projections are located at the edge of the mineralized zone. The compounding character of two kinds of anomalies
shows that the mineralization is controlled by low-resistivity faults and rock bodies and featured by zonation郾 |
