flinteite was approved in 2014 and to date (October 2023) it has been reported only from the Northern
Breakthrough, Great Fissure eruption, Tolbachik Volcanic field, Milkovsky District, Kamchatka Krai, Russia
(3 different localities).
Localities
At the type locality, the Northern fumarole field, First scoria cone, Northern Breakthrough, Great Fissure
eruption, Tolbachik Volcanic field, Milkovsky District, Kamchatka Krai, Russia, flinteite is a common mineral
associated with halite, sellaite,
fluorite, saltonseaite,
chubarovite and hollandite.
Flinteite typically forms prismatic crystals up to 0.2 × 0.3 × 1.2 mm3, their groups, granular
aggregates or crusts up to 0.5 × 5 × 5 mm3
(EJM 27.4.581-588).

field, Milkovsky District, Kamchatka Krai, Russia, In the Arsenatnaya fumarole at the Second scoria cone,
flinteite occurs with langbeinite,
aphthitalite, fluoborite,
sylvite, halite,
tenorite, hematite,
zincite, chubarovite,
krasheninnikovite and
vanthoffite, amongst others.
