Environments
Stolperite is found as inclusions in khatyrkite, or accompanying
icosahedrite and/or
hollisterite and
khatyrkite; it is surrounded by
forsterite, spinel and glass.
Crystals are to 3 μm in size
(Mindat).
Localities
At the type locality, the Khatyrka meteorite, Iomrautvaam massif, Anadyrsky District, Chukotka Autonomous Okrug,
Russia, three new alloy minerals hollisterite,
kryachkoite and stolperite were found in 2016.
Stolperite occurs within khatyrkite, or along with
icosahedrite and/or
hollisterite and
khatyrkite
(AM 102.3.690-693).
The meteorite is a carbonaceous chondrite, rich in
aluminium. More associated minerals include
native aluminium, chromite,
native copper, corundum,
forsterite, glass, hercynite,
native iron, magnetite,
naquite, spinel,
