Supplement of Yang et al. (2026), Table S5: Xikuangshan mine soils and aqueous extracts of these soils (simulated soil-water interaction), measured as ε123Sb; extracts are 0.6 to 2.4 ε heavier than the soil, except background soil XKS-11, with poorly mobile Sb. Locations not published. Samples QL-PS-1, QZ-PS-1x and QZ-PS-2, of unspecified origin, are not included; QZ-PS-2 exactly repeats the values of QZ-PS-1x. Sb from 111 to 10,340 mg/kg, pH 5.1 to 7.5.

| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 0.232 ± 0.05 ‰ | 0.174 / 0.341 ‰ | 10 | mine soil, bulk Mean and standard deviation recalculated from 10 analyses, +0.174 to +0.341 (XKS-1 +0.185; XKS-2 +0.268; XKS-3 +0.250; XKS-4 +0.211; XKS-5 +0.174; XKS-6 +0.341; XKS-7 +0.206; XKS-8 +0.263; XKS-9 +0.201; XKS-10 +0.223); published as ε123Sb (1.74 to 3.41 ε) and divided by 10; contents 111 to 10,340 mg/kg. | Yang et al.
