Xikuangshan rivers and streams (Qingfeng, Tanjia, Feishuiyan, Xuanshan)
Hunan, Lengshuijiang, Xikuangshan district, China
Rivers and surface water
- Type
- River or surface water
Xikuangshan antimony mine: 28 waters sampled in November 2013, including 23 springs of aquifers A, B and C, one mine water and four surface waters; arsenic up to 1274 µg/L in springs and 2545 µg/L in rivers, ascribed mainly to leaching of alkaline arsenic residues from the smelter and interaction with stibnite and silicified limestones. Sulfate (δ34S from -0.7 to +4.7 ‰ except B6) comes from sulfide oxidation, mixed with mine and surface waters; no link between δ34S and arsenic (Wen et al., 2018). Labels and 87Sr/86Sr from Table 1 of the published version. Coordinates not published (map only). Four surface waters from the Qingfeng River, the Tanjia and Feishuiyan streams and the Xuanshan River; 152 to 2545 µg/L As, influenced by mine waters and leaching of wastes and slags.
