利用双频激电仪对称四极装置在贵州省安龙县戈塘金矿矿区内进行了微细浸染型金矿体形态探测,对比研究了山区地带对称四极测深法对数模式极距序列和指数模式极距序列探测效果的优劣性,通过分析反演得到了极化体极化反应程度、矿体埋藏深度、矿体赋存形态。研究表明:指数模式极距序列在山区地带的测深效果优于对数模式极距序列。因此,在山区地带进行对称四极激电测深时宜采用指数模式极距序列。
The morphology of the finely disseminated gold ore bodies was probed in the Geotang gold deposit in Anlong County, Guizhou Province by means of the symmetrical quadrupole device of the dual-frequency exciter. The logarithm mode polar distance sequence And exponential mode polar distance sequence detection results, the degree of polarization reaction, the depth of ore body burial and the ore body morphology were obtained by the analysis inversion. The results show that the exponential polar sequence is better than the logarithmic polar sequence in the mountainous area. Therefore, exponential polar sequence should be used in the symmetrical quadrupole sounding in mountainous areas.
