There are Quaternary remnants of glaciation in north and central part of Huanggangshan tin copper deposit in Keshiketeng County of Inner Mongolia. Gravel layers which were composed of residual slope sediments and ice pickles occurred under the surface which vegetation developed well. Its thickness is than 3m. Thus, it is difficult to carry out surface geological work in this area. In order to improve prospecting effect, induced polarization measurements with the scale of1 ∶10000 has been carried out. Through verification and analysis on IP anomalies, in the boundary of southwestern DJH-1 induced polarization anomaly, and the inside and outside contact zones of early Yanshanian porphyritic fine-grained biotite monzogranite and both sides of the quartz diorite rock and granite porphyry, multi-stage of magmatic intrusions have been found with strong mineralization and alteration. At present, 10 tin ore bodies and 8 cooper ore bodies have been circled. The ore bodies which have been circled have good correspondence with the ore bodies found by induced polarization anomalies. It will provide an important basis for further geological exploration work.
