Hydrothermal environments
Saléeite is a secondary mineral occurring in the oxidised zone of
uranium-bearing polymetallic hydrothermal and sedimentary mineral deposits, associated with
torbernite, autunite,
zeunerite, bassetite,
dewindtite, sabugalite,
phosphuranylite and dumontite
(Mindat,HOM).
Localities
At Tom's quarry, Kapunda, Mount Lofty Ranges, South Australia, saléeite is associated with
fluellite, aldermanite,
wavellite, cacoxenite,
apatite and minyulite (AJM 17.1.25).
