摘要
对代家庄铅锌矿地物化综合勘查中物探在不同找矿阶段所起作用和效果进行了再认识。首先利用区域重磁场特征划分东、西秦岭的分界,揭示出东、西秦岭不同的地质构造背景和控矿的差异性;激电测量借助探测目标物的物性差异普详查起到间接找矿作用;据高精度磁测弱异常差异,探讨了成岩成矿的氧化还原环境;利用可控源音频大地电磁测深,在探采阶段,由已知含矿部位向外围进行定位预测指导采矿。
This paper puts forward some new opinions concerning the role and effect of geophysical exploration in different ore-prospec-ting stages of the integrated geophysical-geochemical exploration of the Daijiazhuang Pb-Zn deposit. The regional gravity and magnetic field characteristics were firstly used to determine the boundary between East Qinling and West Qinling and reveal the different geolog-ical-geochemical backgrounds and ore-controlling conditions;the IP measurement played the indirect ore-prospecting role in the recon-naissance and detailed investigation stages by means of detecting differences in physical characters of the objects;the rock-forming and ore-forming oxidation and reduction environment was investigated by means of high-precision magnetic measurement of the difference of weak anomalies;during the exploration and mining stage, the CSAMT was used to extend the known ore-bearing position outward, make locating and predicting and guide the mining work.
