Thalhammerite is a relatively new mineral, approved in 2018. Associated minerals include
braggite, vysotskite,
stibiopalladinite,
telargpalite, sobolevskite,
kotulskite, sopcheite,
moncheite, malyshevite,
insizwaite, acanthite,
gold-bearing silver,
kravtsovite, vymazalováite,
galena, chalcopyrite,
bornite, millerite and
pyrite
(HOM).
Localities
At the type locality, the Komsomol'skii mine, Talnakh Cu-Ni Deposit, Noril'sk, Putoran Plateau, Taimyr Peninsula,
Taymyrskiy Autonomous Okrug, Krasnoyarsk Krai, Russia, thalhammerite occurs in vein-disseminated
galena-pyrite-chalcopyrite
and
millerite-bornite-chalcopyrite
deposits hosted by
diopside-hydrogrossular
metasomatites developed in
diopside-monticellite
skarn. It occurs as tiny inclusions, from a few μm up to about 40–50 μm,
intergrown in pyrite,
chalcopyrite, and also in
bornite. Other associated minerals include
millerite
(HOM, Mindat).
At the Southern Kievey Fedorovo–Pana layered intrusion, Fedorovo-Pansky massif, Murmansk Oblast, Russia,
thalhammerite occurs in platinum group element ores in a layered
intrusive
(HOM).
