Saleeite

Saleeite

More properly spelled Saléeite, this mineral is named for Achille Salée, who was a Professor of Geology at the Catholic University of Louvain in Louvain, Belgium. Saleeite can be found in the oxidized zones of U-rich metallic hydrothermal deposits as well as some U-rich sedimentary deposits. Saleeite can be found in many localities. It is strongly radioactive.
