Dafulou (Dachang ore field)
Dachang ore field, Nandan County, Hechi, Guangxi, China
Other hydrothermalSn-Zn-Sb-Cu
- Type
- Stratiform bodies and tin-polymetallic veins in black shale
Deposit in the eastern part of the Dachang field: stratiform bodies in Lower Devonian black shale and mudstone, and veins cutting the Lower and Middle Devonian; cassiterite, pyrrhotite, sphalerite, pyrite, quartz, calcite and fluorite (Fan et al., 2004). Sulfur less negative than at Huile and Kengma, a sign of magmatic influence according to the authors. Coordinates of the Dachang ore field, to within a few kilometres. Indicative coordinates.
