- Cari Corrigan, Tim McCoy, Nicole Lunning
The section exhibits a range of chondrule sizes (500 micron to 2 mm), that are well-defined and metal-rich along with CAIs in a dark matrix of FeO-rich phyllosilicate. Polysynthetically twinned pyroxene is abundant in chondrules. Silicates are unequilibrated; olivines range from Fa1-33, with most Fa0-2, and pyroxenes from Fs2-4Wo1. The meteorite is probably a CR2 chondrite.
