Macroscopic Description - Kathleen McBride | |
The exterior fusion crust is black with polygonal fractures. The interior matrix is gray with minor rust and vague chondrules. | |
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach | |
The section consists of only one very relict chondrule in a matrix of finer-grained silicates, sulfides and very abundant magnetite. The meteorite is only slightly weathered. Silicates are homogeneous. Olivine is Fa28, with one at Fa53 and one orthopyroxene analysis was Fs21Wo15. The meteorite appears to be a CK6 chondrite. |
