Sulphide, wurtzite group, forms a series with wurtzite, paramorph of keilite, rudashevskyite and troilite
To date (March 2021) buseckite has been found only at the type locality, the Zaklodzie meteorite, Zamość County, Lublin Voivodeship, Poland. Buseckite is the Fe-dominant analogue of wurtzite, 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).
