Macroscopic Description: Kathleen McBride
60% of the exterior has smooth, thin brown/black fusion crust with polygonal fractures. The interior is a soft and friable tan matrix with green inclusions ranging in size from 1-7 mm.


Thin Section (,2) Description: Tim McCoy
The section shows a groundmass of coarse (up to 1.5 mm) comminuted olivine of composition of Fa26 (Fe/Mn ~ 42) with minor troilite, metal and spinel. The meteorite is tentatively classified as a clast from a mesosiderite -- where similar olivine-rich clasts have been reported -- but the possibility that it samples the missing dunitic component from the HED parent body should be considered.
