摘　　要：贵州黔西南属于山区,地形地质条件复杂。准确探测黔西南微细浸染型金矿的矿体形态和赋存状态,是高效开采该类金矿的一个难题。利用双频激电法在贵州黔西南安龙县戈塘金矿进行频率域激电中梯扫面和频率域激电测深工作,对黔西南微细浸染型金矿的矿体形态进行探索性物探试验。结果表明:激电中梯工作所圈定的激电异常区域基本能够反映矿体的范围;激电测深工作基本能够反映矿体的倾向、延深及埋深等产状特征;双频激电法可以适应贵州的山区地形以及微细浸染型金矿的复杂地质条件,在该类型金矿的形态探测、解决因矿体边界不清而导致的开采效率低下、矿石贫化严重等问题方面有一定价值。Southwest Guizhou belongs to mountainous area ,its topography and geological conditions are complicated .Accurate detection of micro-disseminated type gold ore body shape and occurrence state is a problem for the efficient exploitation of the gold mine .Using dual-frequency IP method to conduct frequency domain IP ladder sweep and frequency domain IP sounding in Anlong county′s pond gold mine of Southwest Guizhou ,the Southwest Guizhou micro disseminated type gold ore body form of exploratory geophysical experiment was carried out .The results show that induced polarization of work outlining basic IP anomaly region in the ladder can basically reflect the scope of ore body ;The IP sounding work can basically reflect the tendency of the ore bodies ,the deep and occurrence characteristics of buried depth;Dual-frequency IP method can adapt to Guizhou mountainous terrain and complex geological conditions of the micro disseminated deposits ,it also have certain value in detection for the morphology of this type gold ore exploration ,ore body mining boundary is not clear due to the problems such as low efficiency ,severe ore dilution aspects .
