Maoping
Yiliang, north-eastern Yunnan (Sichuan-Yunnan-Guizhou province), China
Mississippi Valley TypeZn-Pb (Ge)
- Type
- Zn-Pb hosted in Devonian-Carboniferous carbonates (MVT type)
Third-largest Pb-Zn deposit of the Sichuan-Yunnan-Guizhou province (25 Mt ore at 12 to 35 % Zn + Pb), in fault-fold traps. Lead from thorough mixing of the host carbonates and the Neoproterozoic basement (Kunyang and Huili groups); zinc mainly from the basement; precipitation by mixing of a metal-bearing and a reduced sulfur-bearing fluid. Indicative coordinates.
