- Disseminated and stockwork tungsten in subvolcanic rocks
Disseminated, stockwork or brecciated tungsten deposit in subvolcanic rocks. According to Zhang (1988), strongly 18O-depleted wolframite: open system, sudden decompression and meteoric water influx. Deposit not located: the romanised name in the paper could not be matched to a known mine.
