- Type
- Sediment-hosted Carlin-type disseminated gold
Carlin-type gold deposit in calcareous siltstones and claystones of the Xinyuan and Bianyang formations (Middle Triassic). Li et al. (2020): four quartz generations (YTi to YTiv); fluid inclusions at 140 to 260 °C and 2.4 to 7.4 wt% NaCl eq.; initial fluid δ18O of +7.7 to +10.6 ‰, then heavier through wall-rock interaction. Initial fluid similar to that of the Qinglong antimony. Coordinates not published.
