Daoga gold mining area is located in the east section of Beishan metallogenic belt��Ejina County�� Inner Mongolia�� The orebody of this area occurred in shallow metamorphic clastic rocks of Suishishan Formation and Hercynian diorite��and the distributions of the orebody are strictly controlled by NE and EW fault structures�� Gold- bearing quartz vein is the main mineralization type in this area��and the ore is mainly formed by brecciated sulfide- rich quartz veins and tourmaline- quartz veins in type��and the genesis of gold mineralization of this area is belong to mesothermal vein type�� Based on the analysis of IP anomaly of vein��and vein ���� apparent chargeability of anoma- ly range of is from 5% to 9% and apparent resistivity is from 50 ٷm to 300 ٷm��which is considered the IP anomaly with low resistivity and high polarization in the surveyed area as the effective geophysical ore- hunting indication��
