Large-scale mafic-ultramafic related Cu-Ni-PGE deposit, consisting of nine Carbonaceous mafic-ultramafic intrusions, of which intrusion no. 1 is the largest. It is lenticular in plan view, 640 m long, and 35 to 350 m wide, trends NW, and dips at 20 to 28° NE. In cross section, the pluton is wedge-shaped with a wide upper, and narrow lower part. The marginal upper part consists of biotite diorite and gabbro, and contains sparse sulfides. The central upper part is gabbro and norite and consists mainly of biotite-amphibole norite, gabbro, and quartz-amphibole norite, and contains lean Cu-Ni sulfides at the base. The central lower part is biotite-amphibole norite, biotite-olivine norite, and peridotite with more abundant sulfides at depth. The marginal lower part is biotite-amphibole diabase and gabbro, and olivine-amphibole diabase and gabbro, and contains lean sulfides. The intrusion is ultramafic with a Mg/Fe ratio of 2/3. Ore minerals occur in masses and disseminations. Autometamorphism is widespread with formation of serpentine, talc, bioitite, and uralite.
Reserves include 420,000 tonnes of Cu, 240,000 tonnes of Ni, more than 4,000 tonnes of Co, 2.5 tonnes of Pt and 3.4 tonnes of Pd. Located 28 km SE of Fuyun city.
