Anotace

V originále

The Rožná uranium deposit is hosted by mylonites and cataclastites that formed during the Westphalian and Early Stephanian ductile to brittle shearing of the overthickened Variscan crust. The shearing was associated with the formation of white mica and widespread chloritization and sulphidation of the high-grade metamorphosed country rock. During Late Stephanian and Lower Permian, chloritized zones were infiltrated by saline, oxidized basinal brines capable to dissolve uranium from the host rock complex. The brines were reduced by Fe2+ silicates and pyrite, giving rise to syn-ore alterations consisting mostly of Fe-illite and hydrooxides of iron. During the Triassic and Jurassic periods, the Alpine tectonic and thermal reactivation resulted in the formation of post-ore sulphide-barite-fluorite mineralization, argilitization and silicification of host rocks and in local remobilization of uranium.
