This meteorite is paired with a number of earlier-described QUE samples, including 94204/97348/97289/99059/99122/99157/99158. The section consists of mm-sized enstatite grains (Fs0-1), SiO2, zoned plagioclase (An28-34), metal, troilite, daubreelite, alabandite and schreibersite. The latter phases often occur as rounded enclaves in the enstatite. These meteorites are unusual aubrites or enstatite chondrite impact melt rocks.
