Abstract: 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.
