- Type
- W-Cu quartz veins and related granites
Recently discovered deposit in the Dahutang W-Cu ore field (2 Mt WO3, 0.65 Mt Cu and 0.08 Mt Mo), related to Mesozoic S-type granites (150 to 130 Ma) intruding the Neoproterozoic Jiuling batholith granodiorite and the Shuangqiaoshan Group; over 95 % of W and Cu in quartz veins, W before Cu. Hu and Jiang (2020): magmatic tourmalines averaging -13.8 to -14.8 ‰, tourmaline of late copper veins lighter (-16.5 ‰), external fluid input.
