Macroscopic Description - Kathleen McBride
The exterior is rusty brown in color with no fusion crust visible. The interior is a brown matrix with metal and white to light gray chrondrules.
Thin Section (,2) Description - Cari Corrigan and Linda Welzenbach
This section shows an aggregate of chondrules (up to 1 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide, including daubreelite. Microprobe analyses show pyroxene is Fs1. Kamacite contains from 2.7-3.0 wt.% Si. This meteorite is an EH chondrite, probably a type 4.
