Soils
- Type
- Soil
Antimony smelters south-west of the Dushan County antimony district (Guizhou): an old one, opened in 1973 and active for over 40 years, and a new one since 2015; prevailing south-easterly winds. Smelter materials at δ123Sb of +0.29 to +0.38 ‰ (mean +0.33 ± 0.08 ‰), soils with a geogenic value of +0.61 ‰ (Liao et al., 2023). Attached to the Banpo deposit, the main occurrence of the district, by proximity. Coordinates not published. Profile sampled in 2016 in a low position near the river and the smelter; Sb from 74.6 mg/kg at the surface to 5.1 mg/kg at depth, no migration below 50 cm. Smelter Sb is depleted in the heavy isotope at 0-10 and 25-80 cm and enriched at 10-25 cm: adsorption and reductive dissolution according to the authors.
