85% of this ordinary chondrite‘s exterior is covered with brown/black fusion crust with some oxidation. The interior is a dark gray to black matrix with abundant chondrules and inclusions of various sizes and colors.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The section exhibits numerous large (up to 2 mm), well-defined chondrules in a dark matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Staining from weathering is pervasive. Silicates are unequilibrated; olivines range from Fa7-35 and pyroxenes from Fs2-5. The meteorite is an L3 chondrite (estimated subtype 3.5).
