Writeup |
Writeup from AMN 19(2):
Macroscopic Description: Carol Schwarz The exterior surface of this small flat fragment is dark brown with a few mm-sized yellow and green mineral grains visible. Some evaporite is also present. The interior is dark brown, mostly metal, with yellow and brown crystals scattered throughout. Thin Section (,2) Description: Brian Mason This section shows plagioclase and pyroxene clasts, up to 1.2 mm across, in an opaque matrix of nickel-iron and troilite (the nickel-iron extensively weathered to limonite). Most of the pyroxene is hypersthene, with composition near Wo3Fs28, but one grain of augite, Wo40Fs27, was analyzed. Plagioclase composition is An91-96. One grain of tridymite was analyzed. The meteorite is a mesosiderite, and can be confidently paired with QUE86900. | ||||||||||||||||||||
