| 摘 要： | 为了提高找矿效率,查清铜矿在深部的空间位置和隐爆角砾岩筒的发育情况,在矿区首次开展了可控源音频大地电磁法(CSAMT法),采用V8多功能电法勘探系统,选择围绕青龙山角砾岩筒布设了3条CSAMT剖面。通过二维反演计算,结合研究区地质特征和岩矿层物性特征,对测量的3条剖面隐爆角砾岩筒形态及岩矿层进行精细的解释,为确定隐爆角砾岩筒及岩矿层在深部空间的位置提供了重要信息。通过钻探验证,其揭露的含矿层位、构造位置和CSAMT方法解释结果吻合较好,找矿效果较为显著,CSAMT法有望作为重要手段在同类型的铜矿勘查预测中推广运用。

| Abstract: | In order to improve the efficiency of prospecting and exploration, the controlled source audio frequency magnetotelluric method was first carried out in the mining area to find out the location of the copper mine in deep space and the development of the cryptoexplosive breccia tube, The V8 multifunction electrical prospecting system was applied in three CSAMT sections around the breccia tube in Qinglongshan. Interpretation of the three CSAMT sections based on two-dimensional inversion method,combined with geological setting and physical properties of the ore-hosting rocks,shed light on the position of the ore- hosting bed,which agrees well with the results of drilling verification in encountered strata and structures.The CSAMT method thus is of the potentiality in the further exploration of similar ore deposits. |
