Name: Queen Alexandra Range 94222 This is an OFFICIAL meteorite name. Abbreviation: QUE 94222 Observed fall: No Year found: 1994 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 4.8 g
Macroscopic Description: Cecilia Satterwhite
Black, weathered fusion crust covers fifty percent of the exterior of QUE94222. The broken surface has distinct, thick, rounded blebs of evaporite deposit. No fusion crust remains on 94220 but there is a minor amount of evaporite deposit on the exterior surface. The interior material of both of these carbonaceous chondrites is medium to dark gray. Small white and light gray inclusions are scattered throughout.
Thin Section (QUE94220,2; 94222,2) Description: Brian Mason
The sections are so similar that a single description suffices; the meteorites are possibly paired. They show a few small chondrules, up to 0.5 mm across, some irregular aggregates, and numerous small mineral grains in a translucent brown isotropic matrix. The mineral grains are almost entirely olivine, near Mg2SiO4 in composition, with a few iron-rich grains. The matrix consist of iron-rich serpentine. The meteorites are C2 chondrites.
