| Macroscopic Description - Roger Harrington | |
| Shiny black fusion crust covers 80% of the exterior surface. The remaining 20% is a light gray medium to fine-grained matrix with medium gray mottling and trace rust spots. This sample has several elongate, oriented voids on the top-west face that range in diameter from 1 to 14 mm. The interior is a light gray medium to fine-grained matrix with medium gray mottling and trace rust spots. | |
| Thin Section Description (,2) - Cari Corrigan | |
| This meteorite is dominated by fine-grained (~200 micron average grain size) basaltic material which occurs as both the host and clasts within these meteorites. Occasional coarser-grained clasts, with grain sizes up to 1.5 mm, are observed. Mineral compositions are homogeneous with orthopyroxene (Fs1Wo2), with lamellae of augite (Fs5Wo5), and plagioclase (An6Or0.8). The Fe/Mn ratio of the pyroxene is ~34. The meteorite is a brecciated eucrite. | |
