简述了勘探区微细侵染型金矿地质特征,岩(矿)石电阻率、充电率电性参数特征。图示说明了改进的三极测深原理和排列方式,该装置具有采集数据量大、激电信号强、穿透深度大、勘探精度高和效率高等优点。数据处理时剔除电磁噪声对激电数据的影响是必需的。激电测深二维反演结果表明三叠系地层百逢组砂岩、细砂岩含金矿段均有明显的中(低)阻-高极化响应特征,钻探验证深部激电(IP)异常见多金属硫化物含金矿脉,改进的三极装置测深在勘探区取得了较好地质效果。
The geological characteristics of the finely-infiltrated gold deposits in the exploration area, the electrical parameters of rock resistivity and charging rate are briefly described. The illustration shows the improved principle and arrangement of three-electrode sounding. The device has the advantages of large amount of collected data, strong galvanic signal, large penetration depth, high exploration accuracy and high efficiency. Data processing eliminates electromagnetic noise on the impact of the data is necessary. The 2D inversion results of the acoustic sounding sounding show that the middle-low resistivity-high polarization response of the Baifeng formation sandstone and the fine sandstone gold-bearing part of the Triassic strata have been verified. Deep IP verification See the polymetallic sulphide-bearing gold veins, improved three-electrode device sounding in the exploration area has achieved good geological results.
