Name: Queen Alexandra Range 99158 This is an OFFICIAL meteorite name. Abbreviation: QUE 99158 Observed fall: No Year found: 1999 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 31 g
Macroscopic Description: Kathleen McBride
10% of the exterior of these meteorites are covered with patchy brown-black fusion crust. The interiors reveal rusty crystalline material that crumbles easily. These meteorites are too rusty to observe any visible inclusions.
Thin Section (,2) Descriptions: Tim McCoy and Linda Welzenbach
These meteorites are so similar that a single description suffices. The section consists of mm-sized enstatite grains (Fs0-1), SiO2, zoned plagioclase (An7-31), potassium feldspar, metal, troilite, daubreelite, alabandite and schreibersite. The latter phases often occur as rounded enclaves in the enstatite. These meteorites are paired with the QUE 99059/94204/97348/97289 grouping. Unlike these earlier members, which contained either plagioclase or SiO2, these three contain both phases. These meteorites are unusual aubrites or enstatite chondrite impact melt rocks.
