- Brecciated and stockwork tungsten ore in a fracture zone
Brecciated or stockwork tungsten-antimony (fluorite) ore in the Devonian fault-fracture zone of northern Guangxi. According to Zhang (1988), very light wolframite and heavy quartz, formed below 200 °C by meteoric water exchanged with 18O-rich Devonian sediments. Deposit not located: the romanised name in the paper could not be matched to a known mine.
