摘要
焦家式破碎带蚀变岩型金矿床上的电阻率测深资料经二阶差分法处理后,可以明显识别深部断裂构造蚀变矿化带的顶界面,并可利用ραm断面图的0-线特征求取其顶界面埋深。电阻率测深资料经变换为轴向测深曲线后,可明显识别深部断裂构造矿化蚀变带,提高了深部垂向分辨能力,突出了深部找矿的地质效果。
By second order difference method processing of the resistivity depth sounding data on the Jiaojia type fracture zone alteration rock pattern gold deposit, the top interface of the deep fracture zone alteration-mineralization belt can be clearly identified and the top interface burying depth can be calculated by the 0- line feature of ρ_α~m section map. Axial depth sounding curves from conversion of resistivity depth sounding data can clearly identify deep fracture zone mineralization-alteration area improving vertical resolution in depth to increase depth ore hunting effectiveness.
