Macroscopic Description - Kathleen McBride
The exterior of this ordinary chondrite has dark brown fusion crust. The interior is a rusty brown matrix with high metal content and chondrules and inclusions of various sizes and colors.
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Pamela Salyer
The section exhibits numerous, large, well-defined chondrules (up to 1 cm) in a black matrix of fine-grained silicates, troilite and rare metal. Polysynthetically twinned pyroxene is abundant. The meteorite is mildly weathered. Weak shock effects are present. Silicates are unequilibrated; olivines range from Fa3-37, with most grains clustered at Fa17 or Fa30, and pyroxenes from Fs15. The meteorite is an LL3 chondrite (estimated subtype 3.2).
