Original Classification LL3.8 Chondrite
Macroscopic Description - Cecilia Satterwhite
These chondrites all have black fusion crust with rusty areas and oxidation haloes. Areas without fusion crust are brown. The interior is a gray to black matrix with some oxidation and metal. Inclusions and chondrules are visible on the exterior as well as the interior and are lighter than the matrix and vary in size.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The sections exhibit numerous large, well-defined chondrules (up to 1.5 mm) and occasional melt clasts in a matrix of fine-grained silicates, metal, and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is abundant. Silicates are unequilibrated; olivines range from Fa2-44 and pyroxenes from Fs3-28. The meteorites are LL3 chondrites (estimated subtype 3.8).
