Macroscopic Description - Cecilia Satterwhite
Small, dull patches of fusion crust remain on QUE 93001 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 Description (,5) - 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 QUE 86900 (AMN 10(2), 1987).

Thank you Paul. Don't be too hard on that Programmer, he is doing the best he can, and you don't want him to quit. |

My apologies for failing to show a picture this morning. It was the Idiot Programmer (again!) who is just now getting a proper beating. |
