Oued Maden
Northern Tunisia, Nappe zone (Jendouba), Tunisie
Mississippi Valley TypePb-Zn (As, Hg, Sb)
- Type
- Carbonate-hosted Pb-Zn (As-Hg-Sb) veins
Nappe zone of northern Tunisia: epigenetic vein, karst and stockwork mineralisation in Upper Cretaceous limestones, below the allochthonous Numidian units; homogeneous crustal lead, Upper Miocene model age (Jemmali et al., 2013). Veins with galena, sphalerite, jordanite, orpiment and realgar, rich in As and Sb; fluids at about 130 ± 10 °C; galena with slightly negative sulphur. Indicative coordinates, derived from the distance to Jendouba (35 km northwest).
