Urangrube, Forstau, Forstautal, Radstädter Tauern, Salzburg, Österreich
Sedimentary uranium deposit with later stage metamorphic and diagenetic alteration. The ore - a mixture of pitchblende and pyrite (most of the other ore minerals do only occur in microscopic quantities) - is included in sericite-quartzite lenses, which form several layers in phyllites and quartz-phyllites of the Radstatt series. This zone in which the uranium is very inhomogeneously distributed, extends from the Taurach valley in the southwest to Styria in the east.
The mine near Forstau worked rich mineralizations in different layers, from two levels, the Barbara adit and the West adit. Exposures with a similar mineralization are found in some places further south in the valley.
