Macroscopic Description - Cecilia Satterwhite
90% of the exterior has brown/black fusion crust with oxidation haloes. The interior is a dark gray to black matrix with abundant chondrules/inclusions. Oxidation is scattered throughout and minor metal is visible.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy and Nicole Lunning
The section shows a close-packed aggregate of chondrules and chondrule fragments (up to 2.25 mm across) in a dark matrix containing a small amount of nickel-iron and troilite. The meteorite is moderately weathered, with brown limonitic staining throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa12-20; pyroxene, Fs5-22. The meteorite is classified as an L3 chondrite estimated to be of subtype 3.8.
