- Wolframite-quartz veins
Wolframite-quartz vein deposit in a Yanshanian granite. According to Zhang (1988), wolframite at about +5 ‰ and quartz at about +12 ‰, formed at about 300 to 350 °C from re-equilibrated magmatic water of W-Sn granites. Prospect of unspecified ore type; limited meteoric water influx according to Zhang (1988). Deposit not located: the romanised name in the paper could not be matched to a known mine.
