Macroscopic Description - Roger Harrington | |
Shiny black fusion crust with several oriented holes covers 90% of the exterior surface. The remaining 10% is a light to medium gray, medium grained matrix. The interior is a light to medium gray, medium-grained matrix with a trace of orange staining. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy, Linda Welzenbach | |
This meteorite is dominated by fine-grained basaltic material which occurs as both the host and clasts within this meteorite. Occasional coarser-grained clasts, with grain sizes up to 1 mm, are observed. Mineral compositions are homogeneous with orthopyroxene (Fs63Wo2), with lamellae of augite (Fs27Wo42), and plagioclase (An89Or1). The Fe/Mn ratio of the pyroxene is ~29. The meteorite is a brecciated eucrite. |
