Macroscopic Description: Kathleen McBride
The exterior of this carbonaceous chondrite has brown/black shiny fusion crust covering 100% of its surface area. It is fractured and has oxidation halos. The interior has a dark matrix with some rust and metal. Irregularly shaped chondrules are light colored, stained with rust. Other inclusions appear rusty, tan and gray in color.

Thin Section (,2) Description: Tim McCoy
The section exhibits large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa_1-31, with most Fa_1-5, and pyroxenes from Fs_1-2. The meteorite is an unequilibrated carbonaceous chondrite, probably a CV3.
