Dong'an (antimoine)
Dong'an County, Yongzhou, south-western Hunan, China
Other hydrothermalSb
- Type
- Low-temperature stibnite veins in the Neoproterozoic basement
Antimony deposit (75,000 t Sb) in Neoproterozoic slates and siliceous rocks, south of the Xiangzhong basin. The only deposit of the Zhai et al. (2026) study with positive Δ199Hg: largest share of a deeply recycled mantle reservoir carrying marine mercury brought in by subduction. Stibnite δ34S near zero (-1.32 to +2.86 ‰). South China antimony belt (Xiangzhong basin), low-temperature hydrothermal domain (about 140 to 250 °C). Position of the county seat. Indicative coordinates.
