Macroscopic Description: Kathleen McBride The dull fusion crust on this achondrite is dark brown and thin and covers approximately 25% of the exterior. The exposed interior has weathered to a cement gray-yellow-orange color. It is pitted and friable. The fresh interior surface is off white to yellow and fine grained, with a sugary/crystalline texture. There are numerous inclusions of various sizes - rounded/subrounded to angular clasts and grains. Some metal and rusting is visible.
Thin Section (,6) Description: Brian Mason The section shows a groundmass of comminuted pyroxene and plagioclase (grains up to 0.2 mm) with a few larger plagioclase clasts (up to 2 mm). Microprobe analyses show that most of the pyroxene is hypersthene (Wo1-4, Fs20-30); one grain of augite, Wo41Fs20, was analyzed, and several grains of intermediate composition. Plagioclase composition is An89-92. One grain of a SiO2 polymorph was analyzed. The meteorite is classified as a howardite.
