Macroscopic Description - Cecilia Satterwhite | |
The exterior is covered with black fractured fusion crust. The interior is a gray matrix with some specks of white inclusions/chondrules. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy, Nicole Lunning | |
The section is composed of several clasts, including one large (~3 mm) clast that contains large (~1 mm) chondrules rimmed by fine grained sulfides and magnetite. The large clast may be a different petrologic type than its host breccia. There is also one large (1 mm) sulfide clast within the matrix. Excluding the clasts, no chondrules are present. The meteorite is moderately weathered, but extensively shock blackened. Olivines range from Fa18-34. The meteorite is a CK3-6 chondrite breccia. |
