摘　　要：目前隐伏金属矿产勘查的深度逐渐加大,勘查区也逐渐向工作程度相对较低、情况更加复杂的山区转移,常规的、单一的物探方法在勘探深度及精度等方面都已经无法满足目前勘查的需要。针对这种情况,本文提出可控源音频大地电磁测深法(CSAMT)与频谱激电法(SIP)的技术组合,并将其运用于河南栾川山区隐伏金属矿勘查实践中。结果表明该方法组合具有勘探深度大、对异常区分能力强、深部分辨率高等特点,是一种有效的勘查技术手段。With the increasing exploration depth of concealed metal deposits, and exploration areas gradually transferring to relatively poorly surveyed and complex mountainous areas, single geophysical methods are unable to meet the present exploration needs in depth and precision. To solve this problem, this work proposes a combined method of CSAMT （ controlled-source audio frequency magentotelluric） and SIP （ spectral induced polarization） technology, and has applied it to the survey of concealed metal deposits in the Luanchuan mountainous area, Henan Province. The results show that this combind method can explore to larger depths, discriminate anomalies well and has higher resolution to deep objects. It is an efficient tool for survevs.
