Environments
Localities
At the type locality, the Dzhalinda Sn Deposit, Malyi Khingan Range, Khabarovsk Krai, Russia,
cassiterite was found to be unusually rich in
indium, including a
primary indium
mineral, indite and a supergene one,
dzhalindite.
Indite occurs in grains mostly less than 0.2 mm, rarely up to 0.5 mm in size and iron-black in colour
(AM 49.439-448).
Indite is of primary hydrothermal origin,
replacing botryoidal cassiterite, and associated with
cassiterite and
dzhalindite
(HOM).
