Abstract This paper briefly introduced the basic theory and working methods of induced polarization (IP) method, and the geological and geophysical characteristics of Dachang antimony ore area in Guizhou. The application effect of IP method in antimony ore exploration was mainly discussed. Through comprehensive analysis and research on anomaly of IP intermediate gradient and IP sounding,the authors attained the spatial variation characteristics of strata resistivity in the study area. Then the strata boundary between the Mount Emei basalt and Longtan sandstone was identified. The structure of the study area was deduced and the ore bearing favorable position was circled. Comparing with the drilling data, the authors found that the geophysical exploration and the drilling data were basically consistent, which indicated that IP has good antimony ore prospecting results(IP).
