Macroscopic Description - Cecilia Satterwhite | |
85% of this meteorite’s exterior is covered by pitted black fusion crust that is frothy on one surface. The interior is a dark gray matrix with oxidation heavy on one end. The matrix is fine grained with small white/gray inclusions and abundant metal. | |
Thin Section Description (,2) - Tim McCoy | |
The meteorite consist primarily of prismatic to granular enstatite (Fs0-1), with rare relict chondrules, abundant Si-bearing metal (~0.7 wt.% Si) and troilite. It is quite fresh, although brown, limonitic staining is found along cracks. The meteorite is an EL6 chondrite. |
