Na Bop-Pu Sap
Cho Don district, Bac Kan Province, Viêt Nam
Other hydrothermalPb-Zn
- Type
- Shear-zone-hosted Pb-Zn veins in Devonian shales and limestones
Veins of galena, sphalerite, chalcopyrite, pyrite, arsenopyrite and pyrrhotite along faults in Devonian shales, claystones and limestones. Deep, probably magmatic sulfur contaminated by marine sedimentary rocks; lead model ages of 424 to 598 Ma. The authors rule out MVT and SEDEX models. Indicative coordinates.
