Macroscopic Description - Kathleen McBride | |
100% black, glassy fusion crust covers the exterior surface. The interior is a light gray matrix with darker gray clasts. Smaller inclusions of white, black and various shades of gray are visible. | |
Thin Section Description - Tim McCoy, Lauren LaCroix, Linda Welzenbach | |
The section consists of rare coarse-grained basaltic clasts up to 2 mm in a comminuted matrix of plagioclase and pyroxene. Pyroxene is commonly twinned with orthopyroxene (Fs49Wo2) containing lamellae of augite (Fs19Wo45). Fe/Mn in pyroxene is ~30. Plagioclase is An82-90. The meteorite is a brecciated eucrite. |
