Carran, Burren, County Clare, Irlande
Mississippi Valley TypePb-Zn
- Type
- Carbonate-hosted Zn-Pb (Irish type), oxidised near surface
Zinc prospect in the Carboniferous limestones of the Burren. Sulfide oxidation at about 15 to 20 °C, under a climate warmer than today (Boni et al., 2019). Indicative coordinates.
