Maoping (tungsten, Jiangxi)
Chongyi County, Ganzhou, southern Jiangxi (Gannan belt), China
Other hydrothermalW-Sn
- Type
- Granite-related wolframite-quartz veins and greisen
One of the largest deposits of the Chongyi-Shangyou-Dayu district: wolframite-quartz veins (63,000 t WO3 and 15,000 t Sn) and greisens (40,000 t WO3), in Cambrian sandstones and slates above a concealed granite. Vertical zonation in five levels ("five-floor" model). Wolframite deposited by simple cooling of an early hot magmatic fluid, quartz by later pulses; meteoric water only in the upper level. Coordinates estimated within Chongyi County. Indicative coordinates.
