Name: Queen Alexandra Range 93001 This is an OFFICIAL meteorite name. Abbreviation: QUE 93001 Observed fall: No Year found: 1993 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 1051 g
Sample No.: QUE93001; 93002 Location: Queen Alexandra Range Dimensions (cm): 10 x 7.5 x 6.5; 1.4 x 1.3 x 0.8 Weight (g): 1050.8; 2.6 Meteorite Type: Mesosiderite
Macroscopic Description: Cecilia Satterwhite Small, dull patches of fusion crust remain on QUE93001 but are gone from 93002. The overall color of the exterior of these two specimens is red-brown. Large and small pyroxene crystals, both green and black in color, are visible on the exterior surfaces. The largest crystal noted in 93001 was 3 x 2 cm in dimension. Numerous fractures penetrate the interior of the specimens making the meteorite easy to break apart. Chipping the specimens revealed an interior that is red-brown, pyroxene-rich, and contains some rounded dark inclusions.
Thin Section (QUE93001,5; 93002,2) Description: Brian Mason The sections are identical and evidently represent a single meteorite. They show pyroxene and plagioclase clasts, up to 2.4 mm across, in a matrix of nickel-iron and minor troilite (the nickel-iron extensively weathered to limonite). Most of the pyroxene is hypersthene, with composition Wo3Fs24, but a few grains of pigeonite were analyzed. Plagioclase compositions are in the range An90-96. The meteorite is a mesosiderite, and can be confidently paired with QUE86900 (AMN 10(2), 1987).
