Other hydrothermalZn-Pb (Cu)
- Type
- Magmatic-hydrothermal polymetallic Zn-Pb (Cu, In, Ga) veins
Xiangxi-Qiandong Zn-Pb metallogenic belt, northwestern margin of the Jiangnan Orogen. Fault-controlled quartz veins with sphalerite, galena, chalcopyrite and pyrite in the upper Banxi Group (Neoproterozoic metasandstones and siltstones with tuffs); fluids at 119 to 132 °C, highly saline (13.6 to 22 wt% NaCl eq.). Magmatic-hydrothermal origin, with deposition by cooling, boiling and mixing with meteoric waters according to Zhou et al. (2017). Coordinates not given.
