Environments
Hloušekite is a secondary mineral derived from highly
oxidised, hydrothermal quartz veins containing disseminated
tennantite, chalcopyrite,
and nickel - cobalt
arsenides. Associated minerals include
veselovskýite, pradetite,
lavendulan, arsenolite,
babánekite and gypsum
(HOM).
Localities
At the type locality, the Geister vein, Rovnost Mine, Jáchymov, Karlovy Vary District, Karlovy Vary Region, Czech
Republic, hloušekite was found on the surface of strongly altered ore fragments containing dominant
tennantite and chalcopyrite.
Associated minerals include veselovskýite,
pradetite, lavendulan,
arsenolite, babánekite and
gypsum. Hloušekite forms thin, lath-like transparent, pale green
crystals, locally elongated reaching up to 3 mm across
(MM 78.1341-1353).
