Medium-scale W-Mo-Be skarn deposit, occurring in the Proterozoic Yanshan Basin zone along the northern edge of the Sino-Korean Plate. The deposit consists of tabular skarns that occur along the contact zone between the coarse-grained Hongluoshan granite (with a K-Ar isotopic age of 178 to 186 Ma) and Middle Cambrian to Middle Ordovician limestone. The deposit is 500 m long, 220 m wide and extends 600 m downdip. The skarn exhibits late-stage pyrite, chlorite, carbonate and silica alterations. Molybdenite occurs in disseminations, veinlets and networks, and is closely related to silica alteration.
