Name: Queen Alexandra Range 94201 This is an OFFICIAL meteorite name. Abbreviation: QUE 94201 Observed fall: No Year found: 1994 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 12 g
Macroscopic Description: Roberta Score
This small, dark-gray to black stone is rounded and polished.
The spotty, brownish-black, remnant fusion crust is difficult
to distinguish from the melted, glassy grains on the exterior
surface. The interior is coarse-grained, crystalline, and glassy.
It is composed of laths or globular grains of transparent or
translucent maskelynite plus dull or glassy-black pyroxene. Several
mafic-rich areas, as large as 5 x 4 mm, were noted. Oxidation
is scattered throughout the interior. Thick evaporite minerals
are concentrated as small blebs.
Thin Section (,3) Description: Brian Mason
The section shows a coarse-grained aggregate of subequal amounts
of pyroxene and maskelynite; the maskelynite as laths up to 3.6
mm long, and the pyroxene as interstitial anhedral to subhedral
grains. Maskelynite is fairly uniform in composition, An55-64.
The pyroxene is pigeonite of variable composition, Wo9-20 and
Fs21-69. The meteorite is a shergottite.
