从目前国内外的勘探技术看,根据金矿床的特点,物探方法主要用于圈定成矿构造及矿化蚀变带。利用大功率激电测深法,在黑龙江老新兴—三间房矿区获得了大量岩、矿石的视电阻率和视充电率参数。利用视充电率,圈定矿区金属离子富集区、金属硫化物、石墨化地层等激发极化体的空间部位,并在矿区相对高的极化率异常区域,确定了深部高极化特征的脉体。
From the current domestic and foreign exploration technologies, according to the characteristics of gold deposits, geophysical methods are mainly used to delineate metallogenic structures and mineralized alteration zones. Using high-power electrical sounding method, the apparent resistivity and apparent charge rate parameters of a large number of rock and ore were obtained in Sanfangfang Mine Area, Heilongjiang Province. The apparent charge rate is used to delineate the space sites of excited polarizer such as metal ion enrichment zone, metal sulfide and graphitized ground, and to determine the characteristics of deep high polarization in the relatively high polarization anomaly area body.
