【摘要】 吉林省夹皮沟矿区位于华北地台北缘东段,是重要的金属矿床成矿带,发育铁、金、银和多金属等各种矿床类型。兴安区作为吉林省桦甸市夹皮沟金矿接替资源勘查项目的一部分,在原来地质工作基础上,开展了物探激电中梯测量、CSAMT法、井中原生晕测量,为成矿预测提供了综合找矿信息。通过激电中梯测量:干扰强,因为是老矿山,如激电测深曲线连续性不好,所以圈定的异常不可靠;通过CSAMT法,认为低阻是测区北西向主成矿构造及旁侧次级构造,这些构造既是导矿又是容矿构造。通过钻探验证见矿,认为CSAMT法结果可以进行间接找矿。更多还原

【Abstract】 Jilin Province, Jiapigou mining area is located in east section of northern edge of the North China Platform, is an important metallogenic belt, where developed iron, gold and silver and polymetallic deposit type etc. Xing’an district, as a part of the Jilin Huadian Jiapigou gold exploration project, on the basis of the former geological work, we carried out geophysical exploration IP intermediate gradient measurement, CSAMT, primary halo measurement in the well, which provide comprehensive prospecting information for metallogenic prediction. The old mines, strong interference, sounding curve continuity is not good, so anomalies delineated are unreliable by IP intermediate gradient;By CSAMT, low resistance is the main metallogenic structure and secondary structure in the NW trending of the surveying area, these structure are both ore guide structure and host structure. By drilling verification, the authors considered, the results of CSAMT method can be indirect prospecting.更多还原
