Bauxite mining district.
Uraniferous bauxite deposits, worked until 1964 with a production of 20,000 tons per year. Total production was about 260,000 tons. Individual mines are located NW and W of Weißwasser, about 15 km ENE of Windischgarsten; one mining symbole is at 47.7497891489301, 14.496434211469026.
Note: Weißwasser coordinates from austrianmap.at.
The karst bauxite of the Unterlaussa mining area can be regarded as an Upper Cretaceous (Turonian) paleosol which was formed in-situ by tropical to subtropical weathering of a precursor sediment on karstified dolostone (Hampl, 2018).
The karst bauxite of Unterlaussa was partly resilificated, deferrificated (bleached) and pyritized. Both of the latter processes are attributed to microbial activity. Moreover, a presumably microbially mediated uranium mineralisation and a massive aluminium-hydroxide bound chromium mineralisation have been identified (Hampl, 2018).
