Environments
Stistaite is found in heavy mineral concentrates from placer deposits
Localities
At the Tamaña River, Novita Municipality, Chocó Department, Colombia, stistaite is found in concentrates from
precious metal placers
(HOM).
At the type locality, the Elkiaidai Stream, North Nuratau Range, Sirdaryo, Uzbekistan, stistaite occurred in
heavy mineral concentrates from placer samples collected from a region of
shaly-sandy sediments, as
well-formed cubic crystals 0.02-0.15 mm in size. Associated minerals include
tin, zircon,
rutile, apatite,
anatase, andalusite,
baryte, celestine,
scheelite and cinnabar
(AM 56.358).
At the Baimka placer deposit, Aluchinskii Massif, Baimka River, Bol'shoi Anyui River Basin, Kolyma area, Bilibinsky
District, Chukotka Autonomous Okrug, Russia, stistaite is associated with tin,
sorosite, herzenbergite,
cassiterite and lead
(HOM).
