Environments
Localities
At the type locality, the Zaklodzie meteorite, Zamość County,
Lublin Voivodeship, Poland, buseckite, the Fe-dominant analogue of
wurtzite, was
discovered in an ungrouped enstatite-rich
achondrite. The type material occurs as single-crystal grains,
4–20 μm in size, in contact with two or more of enstatite,
plagioclase, troilite,
tridymite, quartz and
sinoite. Low-Ni iron,
iron variety martensite,
schreibersite, keilite,
cristobalite and graphite, which
are also present in the type sample, are not observed to be in contact with buseckite
(AM 97.1226-1233).
The meteorite is likely to have derived from the breakdown of high-temperature
pyrrhotite to form troilite and
buseckite after the solidification of sulphide-rich liquids produced by impact melting of an
enstatite-rich rock
(HOM).
