Large-scale polymetallic vein and stockwork deposit, located in the southeastern part of the Daxinganling Hercynian orogenic belt, and hosted by Early Permian, low-grade metamorphosed sandstone, graywacke, sericite slate, and knotted slate. The Yanshannian granite porphyry (Rb-Sr whole-rock isochron age: 148.3 Ma) that intrudes the core of a syncline, is intruded itself by slightly younger granodiorite porphyry and quartz syenite porphyry. The granite porphyry is altered to silica, topaz-beresite, K-feldspar, and chlorite. The ores occur in veins and rarely lenses.
