Tieluping
Henan, Xiong'er terrane (Qinling orogen), NE-trending faults, China
Other hydrothermalAg, Pb
- Type
- Orogenic silver (Ag-Pb) veins in high-grade metamorphic basement
Mesozoic silver deposit of the Au-Ag-(Pb-Zn) orogenic belt of the Xiong'er terrane: 1217 t Ag at 293 g/t and 186,772 t Pb at 3.1 % (Chen et al., 2004a). Three stages: early quartz-pyrite (E, about 373 °C), polymetallic sulfides (M, 210-249 °C) and late carbonates (L, 135-203 °C). Chen et al. (2005): deep early fluid (δD about -90 ‰, water δ18O about 9 ‰, CO2 δ13C about 2 ‰), meteoric late fluid; the early fluid would come from metamorphic devolatilisation of a carbonate-shale-chert sequence (Guandaokou and Luanchuan groups) thrust beneath the terrane during the North China-South China collision.
