80% of the exterior is covered by thin, shiny chocolate brown fusion crust. The light gray crystalline matrix has 1-5 mm black angular inclusions, and 1-2 mm yellow and brown inclusions. |
The section shows a groundmass of comminuted pyroxene, plagioclase, metal and sulfide with larger silicate fragments reaching 2 mm. Orthopyroxene compositions range from Fs28-32Wo2-3 (Fe/Mn ~30) and plagioclase is An77-94Or0-2. The meteorite is probably a silicate clast from a mesosiderite. |
