Macroscopic Description - Kathleen McBride | |
Brown/black patches of fusion crust are visible on the exterior. A light gray matrix is exposed with vugs. The light gray matrix has large white clasts (cm sized) and some small (1-2 mm) dark gray inclusions. The meteorite is friable with no metal. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy, Linda Welzenbach | |
This meteorite is dominated by fine-grained (~200 micron average grain size) basaltic material which occurs as both the host and clasts within the meteorite. Occasional coarser-grained clasts, with grain sizes up to 1 mm, are observed. Mineral compositions are homogeneous with orthopyroxene (Fs62Wo2), with lamellae of augite (Fs26Wo43), and plagioclase (An89Or0.5). The Fe/Mn ratio of the pyroxene is ~29. The meteorite is a brecciated eucrite. |
