Macroscopic Description - Kathleen McBride | |
The fusion crust on this meteorite is black and shiny. The interior is a gray matrix with a few green patches. | |
Thin Section Description (,3) - Tim McCoy, Linda Welzenbach | |
This meteorite consists of 2-3 mm clasts of moderate grain-sized basalts set in a comminuted matrix. The meteorite is extensively shocked. Mineral compositions are homogeneous with orthopyroxene (Fs61Wo2), with lamellae of augite (Fs26Wo44) and plagioclase (An89Or0.5). The Fe/Mn ratio of the pyroxene is ~28. The meteorite is a brecciated eucrite. |
