Skarn-type zinc-lead-silver deposits within an area of about 60 square kilometers, comprising several ore zones. Ore bodies occur in the contact zone between Yanshanian (170-177.4 Ma) quartz monzodiorite intrusives and Middle Proterozoic dolomitic marble of the Gaoyuzhuang Formation, as well as along NW- and NS-trending fault systems in carbonate wall rocks. There is a pronounced zoning of the metasomatic mineralisation within the deposit, from the intrusive contact zone, outward to dolomitic marble along the NW-trending fault system, with three ore-bearing magnesian and manganoan skarn zones being distinguished.
NOTE: Not to be mistaken for the Bajiazi Au deposit in Jilin Province.
