Original Classification Iron-IIIAB
Macroscopic Description - Cari Corrigan and Tim McCoy
This meteorite is a dark brown, flight-oriented specimen with an upper surface that exhibits occasional irregularly shaped, deep indentations. The obverse surface is iridescent and exhibits an original surface overlain by a secondary fusion crust. This fusion crust wraps around the meteorite from the front surface.
Thin Section Description (,2) - Cari Corrigan and Tim McCoy
The meteorite exhibits a medium octahedral pattern with kamacite lamellae of 1.5-1.8 mm width, with interstitial ribbons of taenite, comb plessite and schreibersite. No fusion crust is observed but α2 structure extends ~2 mm into the interior over parts of the section. A single sulfide inclusion of 200 microns across is present. Rhabdites are common throughout the meteorite. The average composition based on a microprobe traverse of 100 points is 7.5 wt% Ni, 0.06 wt% P. The meteorite is likely a IIIAB iron.
