Peisey-Nancroix mine dewatering gallery sediments
Savoie, Ponturin valley (Tarentaise), France
Sediments
- Type
- Sediment
Former Pb-Ag mining and metallurgical site of Peisey-Nancroix (1734-1866), abandoned for over 150 years: on-site roasting and smelting from 1745 to 1824. Metallurgical wastes have a homogeneous δ123Sb (+0.72 ± 0.07 ‰), clearly heavier than the ore (-0.28 to +0.10 ‰), whereas Pb does not distinguish them; contaminated soils (about +0.46 ‰) owe 44 to 78 % of their Sb to slags according to a binary mixing (Guillevic et al., 2024). Sediments at dewatering gallery outlets, highly enriched in Pb (up to 4345 mg/kg) but little in Sb; δ123Sb close to the ore. Indicative coordinates (village).
