摘要
论文介绍了利用时间域激发极化中间梯度法和激电测深相结合的方法在阿巴嘎旗查干诺尔铜多金属矿区的找矿成果。首先,利用时间域激发极化中间梯度法扫面,确定了测区平面异常特征,明确了矿区北部的Ⅲ、Ⅳ、Ⅴ号三处圈闭异常区。其次,采用对称四极测深法,布设三条测深剖面,对前期的三处平面异常进行垂向探测,确定了测区北部的垂向异常特征并发现了极化率异常和多金属矿体之间存在良好的空间对应关系,圈定了多金属矿区内密集体的大致范围。最终,结合地质资料和地质工程的验证,证实了铜矿体的存在。
This paper introduces the prospecting results of the Chagannuoer copper polymetallic ore deposit in the Abagaqi using the combination of the time domain induced polarization intermediate gradient method and the IP sounding method. Firstly, using the time domain induced polarization intermediate gradient method to scan the surface, the anomaly characteristics of the measurement area are determined, and the three trapped anomalies of the III, IV and V in the northern part of the mining area are identified. Secondly, using the symmetrical quadrupole sounding method, three sounding profiles are laid, and the three plane anomalies in the early stage are detected vertically, and the vertical anomaly characteristics in the northern part of the survey area are determined and the polarizability anomaly and polymetallic ore body are found. There is a good spatial correspondence between them,which defines the approximate range of conglomerates in the polymetallic ore district. Finally, the existence of the ore body was confirmed by the combination of geological data and geological engineering verification.
