Epithermal depositsAg (Pb, Zn)
- Type
- Silver veins and veinlets in Carboniferous bioclastic limestone (low-sulfidation epithermal)
Adjacent but separate deposits on the south-western rim of the Shanshui Basin, about 75 km south-west of Guangzhou (112°48′01″ to 112°50′13″ E, 23°00′00″ to 23°00′02″ N). Largest silver deposit of the South China Fold Belt (more than 5000 t Ag after Tu, 2000; about 6000 t at 268 g/t in the text), in the Lower Carboniferous Zimenqiao Group limestone, poor in gold. Inclusions at 230 ± 50 °C and 1.6 to 2.6 wt% NaCl equiv.; mixing of magmatic and meteoric water (δD from -59 to -45 ‰, CO2 δ13C from -6.7 to -0.6 ‰, 3He/4He from 0.5930 to 0.8357 Ra, after earlier work). Liang et al. (2007): quartz 40Ar/39Ar plateau age of 64.3 ± 0.1 Ma and fluid-inclusion Rb-Sr isochron of 68 ± 6 Ma (Himalayan orogeny); lead from the Neoproterozoic basement.
