Macroscopic Description - Roger Harrington | |
Dull black fusion crust covers 5% of the exterior surface. The remaining 95% is a heavily pitted, light gray medium to fine-grained matrix with rust brown mottling. The interior is a light gray, medium to fine-grained matrix with dark gray mottling. | |
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 2 mm, are observed. Mineral compositions are homogeneous with orthopyroxene (Fs0Wo2), with lamellae of augite (Fs6Wo3), and plagioclase (An2Or0.1). The Fe/Mn ratio of the pyroxene is ~34. The meteorite is a brecciated eucrite. |
