摘要
利用先进的物探手段,即剖面性的音频大地电磁测深(AMT)和激电测深在金矿勘查区进行探测。初步查明矿区内地层情况、厚度、断裂构造分布特征及矿物的激电异常反应,发现隐伏的矿化蚀变带及向下延伸情况。通过分析物探异常与矿(化)体的关系,从而寻找深部金和其他有色金属矿体,对金矿勘查区内的矿体加以控制,大致查明矿区蚀变带数目、分布、规模、形态及产状等,为下一步探矿工程布置提供依据。
The use of advanced geophysical exploration methods (profile sexual audio-frequency magnetotelluric sounding (AMT) and shock electrical sounding) in gold exploration area detection, the initial identification of mining area of the mainland, thickness, fracture distribution and mineral of IP anomalies electricity, found that concealed the mineralized alteration belt and extending down. Through the analysis of geophysical anomalies and ore (change) body relation, which for deep gold and other non-ferrous metal ore body, gold ore exploration area of the controlled, find out altered with roughly mining area number, distribution, size, shape, form in etc, for the next step exploration engineering arrangement provides the basis.
