Localities
At the Mangabeira deposit, Monte Alegre de Goiás, Goiás, Brazil, dzhalindite occurs in sulphides hosted in
greisenised granite,
and associated with roquesite,
sphalerite, chalcopyrite,
digenite, arsenopyrite,
cassiterite and scorodite
(HOM).
At the Mount Pleasant mine, Saint George Parish, Charlotte county, New Brunswick, Canada, dzhalindite has
been found associated with calcite,
galena and quartz along fractures
in sphalerite which is charged with finely exsolved
chalcopyrite and rare
stannite.
The development of dzhalindite along fractures is indicative of a later and, possibly,
supergene origin. Zinc,
iron and tin are present in the
dzhalindite, but copper was not detected, suggesting that the mineral
was not formed through the alteration of roquesite. In contrast to the
Russian sample, the Mount Pleasant dzhalindite is not associated directly with an
indium-rich mineral and there is no evidence for
supergene alteration other than that the dzhalindite
is later than the sphalerite in which it occurs
(CM 10.781-786).
At the type locality, the Dzhalinda Sn Deposit, Malyi Khingan Range, Khabarovsk Krai, Russia, dzhalindite is
probably of secondary origin from its occurrence along
fractures through primary hydrothermal minerals associated
with brecciated felsic
volcanic rocks. Associated minerals include indite,
cassiterite and quartz
(HOM).
