Abstract The Weimusi tungsten-manganese polymetallic deposit in Song County, tectonically located at the junction of Xiong'er Mountain uplift and Songxian fault basin in the eastern section of Huaxiong platform margin depression, is a new type of W-Mn polymetallic deposit discovered in western Henan Province in recent years. The orebodies are occurred in the NW-trending fracture zone on the margin of fault basin, controlled by formation lithology, structure and magmatic hydrothermal fluid. Three W-Mn polymetallic orebodies are delineated, with paragenesis of W, Mn, Pb and Fe. The genesis of deposit is closely related to postmagmatic hydrothermal filling and metasomatism, belonging to the postmagmatic hydrothermal W-Mn polymetallic deposit.
