Environments
Airdite is a new mineral, approved in 2020 and to date (April 2025) reported only from the type locality.
Localities
The type locality, the Spring Creek Mine, Wilmington, District Council of Mount Remarkable, South Australia, is
located within the contact zone of quartzite and
slate. Mineralisation occurs in a heavily
brecciated, hydrothermal vein.
Primary ore comprises
native copper and cuprite, and minor
chalcocite, chalcopyrite,
covellite, and pyrite.
Secondary minerals occur in small cavities in
quartz veins and have crystallised from low-temperature hydrothermal
solutions. The secondary mineralogy comprises oxide, carbonate,
sulphate and phosphate minerals.
Airdite occurs in cavities in a quartz matrix, associated with
copper, cuprite and
fluorapatite. Airdite occurs as aggregates of pale green, thin platy
crystals up to 0.5 mm across. Individual crystals are up to 80 microns across. Crystals are transparent, with a
vitreous lustre and pale-green streak
(CJMP 63.191-192).
