Abstract The Adatangounao Cu polymetallic deposit is located in the Variscan Qimantage-Dulan Fe-Co-Cu-Pb-Zn-Sn-wollastonite Grade-Ⅲ metallogenic belt. Five Cu-Pb-Zn mineralized belts are discovered, including seven Cu and Pb-Zn orebodies. Mainly controlled by fault structures, the orebodies are characterized by various alterations such as limonitization, pyritization, sericitization, silicification, and carbonatization. The ore-controlling factors and their prospecting significant for the area are discussed by analyzing the geological characteristics of the deposit.
