Macroscopic Description - Cari Corrigan and Linda Welzenbach
This kidney-shaped meteorite has a very smooth exterior surface partially (30%) covered by fusion crust with little oxidation. One prominent fracture cuts across the long axis of the sample and extends to the interior. One end, which is saddle-shaped, shows minor flow bands.
Thin Section Description - Tim McCoy, Cari Corrigan and Linda Welzenbach
The meteorite was examined from a cut and etched surface, which bisected the smaller end or nose of the specimen. The surface exhibits prominent kamacite lamellae with bandwidths less than 0.3 mm set in approximately 30-40% plessite fields. The meteorite exhibits alpha-sub-2 structure throughout. Fusion crust is preserved over a portion of the thin section and reaches a width of ~100 microns. A line scan across the meteorite suggests a composition of 8.0 wt.% Ni and 0.09 wt.% P. The meteorite is an iron. The composition might suggest IIIAB, although it is similar to IVA irons and the bandwidth is typical of IVA irons. Given these facts, we suggest a preliminary classification as group IVA.
