Hydrothermal environments
Although ankinovichite was approved in 2002, to date (May 2025) it has been reported only from the
type localities.
Localities
There are two co-type localities, Kurumsak V Deposit, Aksumbe, Sozak District, Turkistan Region, Kazakhstan and
Kara-Chagyr Mountain, Kadamjay District, Batken Region, Kyrgyzstan.
At Kara-Chagyr Mountain, Kadamjay District, Batken Region, Kyrgyzstan, ankinovichite occurs in fractures and
as cement in schist fragments within a
serpentinite matrix. Associated minerals include
allophane, kolovratite,
volborthite,
nickelalumite,
metatyuyamunite,
roscoelite, tangeite and
gypsum
(HOM).

At the Kurumsak V Deposit, Aksumbe, Sozak District, Turkistan Region, Kazakhstan, ankinovichite is a
low-temperature hydrothermal or weathering-derived mineral that occurs as overgrowths оп
alvanite in vanadium-bearing
schists. Associated minerals include
alvanite, volborthite,
carnotite and goethite
(HOM).
