North Bohemian Uranium District, Liberec Region, Bohemia (Böhmen; Boehmen), Czech Republic

(uranová ložiska severočeské křídy)

Important uranium accumulations at the base of Cretaceous (Cenomanian) sediments. Several so-called deposits (Stráž, Hamr, Holičky, Osečná – Kotel, Břevniště, Hvězdov) were exploited by underground mining and acid leaching.

Characteristic for this deposits is U-Zr-P-Ti (mostly microscopic) mineralization. It is present in a form of sandstones matrix. Mineralization is divided between uranium and uranium-zirconium subtype. Major minerals with economical importance are oxides of U4+ (uraninite s.l.), ningyoite and uranium-bearing "hydrozircon". Less abundant are "uranium-bearing leucoxens s.l.", coffinite and vyacheslavite.
