Original Classification Iron (IAB-IIICD)
Macroscopic Description - Cari Corrigan and Linda Welzenbach
This roughly spherical meteorite is heavily pitted with one end appearing to be broken. The exterior surface has a prominent fusion crust with rust halos associated with pitting. Some pits have a distinctive linear aspect that suggests a Widmanstätten structure.
Thin Section Description - Tim McCoy, Cari Corrigan and Linda Welzenbach
The meteorite was examined from a cut and etched surface, which bisects the specimen. The meteorite appears to have been heavily shocked and exhibits α2 structure throughout, with abundant Neumann bands and little Widmanstätten pattern preserved. A heat altered zone ~800 microns thick underlies a small amount of highly weathered fusion crust. The meteorite is polycrystalline with large kamacite grains up to 2 mm wide (L/W ~5) separated by thin ribbons of zoned taenite which reach up to 100 microns in width and which have been preferentially weathered producing veins of hydrated iron oxides cross-cutting the specimen. Scattered pockets of graphite, in many cases mixed with hydrated iron oxides of terrestrial origin, are found throughout the meteorite. A line scan across the meteorite suggests a composition of 7.0 wt.% Ni and 0.2 wt.% P. The meteorite is an iron. The composition and bandwidth suggest a tentative classification of IAB-IIICD.
