Name: Queen Alexandra Range 94200 This is an OFFICIAL meteorite name. Abbreviation: QUE 94200 Observed fall: No Year found: 1994 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 165.4 g
Macroscopic Description: Cecilia Satterwhite
The exterior of this meteorite has dull, black fusion crust that
is patchy on some surfaces. Areas devoid of fusion crust have
a dull gray color. Some small green, black, and white minerals
are visible. The interior of this meteorite is light gray and
contains abundant, mostly small inclusions; however, a few larger
inclusions are present. The inclusions are white, green-black,
and gray in color. The black inclusions are the largest; one
rounded inclusion is 0.6 cm. Other black inclusions vary in size
from 0.2 to 0.5 cm. One basaltic clast is visible. Weathering
is minor.
Thin Section (,5) Description: Brian Mason
The section shows a microbreccia of pyroxene and plagioclase clasts
in a comminuted groundmass of these minerals. The pyroxene is
orthopyroxene with a minor amount of pigeonite; orthopyroxene
clasts are up to 1.8 mm across, whereas pigeonite clasts are smaller
(maximum 0.3 mm). Microprobe analyses show pyroxene compositions
ranging from Wo1Fs18 to Wo11Fs43. Plagioclase compositions range
from An74 to An93. Accessory amounts of an SiO2 mineral, probably
tridymite, are present. The meteorite is a howardite.
