Meteorites

Zolenskyite is a new mineral, approved in 2020 and to date (September 2022) reported only from the type locality.

Localities

At the type locality, the Indarch meteorite, Hindarx, Aghjabadi District, Azerbaijan, zolenskyite occurs as euhedral to subhedral crystals 10-20 microns in size within troilite, with clinoenstatite and tridymite, in the matrix of the EH4 enstatite chondrite.
("EH4" meaning: E for enstatite, H for high iron content, 4 for type 4, ie with abundant chondrules, which are spherical mineral grains within the chondrite).
Zolenskyite is a paramorph of daubréelite. It may be a high-pressure phase, formed from daubréelite at high pressures of several gigapascals and moderate temperatures in highly shocked regions of the EH parent asteroid before becoming incorporated into the meteorite via impact mixing (AM 107.6.1030-1033).
