Abstract: Through the analysis on the geological feature of Zhaojinggou polymetallic Nb-Ta deposit in Inner Mongolia,it suggests that the acidic rock of Yanshannian is the prospected ore body,which is jointly controlled by stratus,structures and igneous rocks.It belongs to a low-and-medium temperature magmatic hydrothermal vein-type type Nb-Ta polymetallic ore deposit.Albitization and amazonitization are the direct prospecting criteria for Nb-Ta polymetallic deposit in this area.
