Theux
Eastern Belgium (Liège province), Belgique
Mississippi Valley TypeZn-Pb
- Type
- Oxidised MVT with non-sulfide ore (calamine)
Small concession mined until 1925: zinc and lead carbonates, iron and manganese oxyhydroxides, abundant hemimorphite. Deposit of the eastern Belgian Zn-Pb district, with sulfides and calamine (zinc carbonates and silicates); supergene smithsonite and cerussite formed below 70 °C from meteoric waters. Indicative coordinates.
