Paleokarst-hosted uranium deposit in Lower Carboniferous limestone. Mineralization is localized in cavities and fault-breccias formed by dissolution of carbonates. Four episodes of karst formation are recognized: late Triassic-early Jurassic, late Jurassic-early Cretaceous, Cretaceous-Tertiary and Recent. Field relations indicate that the main uranium mineralization is related to the second karst episode.
