Hunan, Lengshuijiang, Xikuangshan district, China
Rivers and surface water
- Type
- River or surface water
Xikuangshan antimony mine (N 27.7°, E 111.4°), mined since the 19th century, northern mine turned into a smelting area; samples taken in October 2022 along the Qingfeng and Lianxi rivers, tributaries of the Zijiang. All compartments have positive δ123Sb, +0.008 to +0.57 ‰ (Shi et al., 2025). Point coordinates not published (supplement Table S1). Waters at 0.68 to 1.20 mg/L Sb for W3 and W5, Sb(V) dominant; W3 carries the rock signature (weathering), W5 that of dust and tailings. Indicative coordinates (district centre).
