Macroscopic Description - Rachel Funk

30% Brown fusion crust. There are several fractures cutting through the meteorite. The exposed surface is brown with red/orange rust. The interior is a black/brown matrix full of orange rust and metals.

Thin Section Description (,2) - Cari Corrigan, Tim McCoy

This section is dominated by fine grained, equigranular impact melt (dominantly olivine), with unmelted clastic material up to 2 mm. On one edge of the section, the impact melt has quenched to a glass adjacent to one of these unmelted clasts. Rounded to ovoid droplets exhibit intergrowths of metal and sulfide. In some locations, metal seems to be preferentially located at one edge of the inclusion, suggestive of gravitational orientation. Olivine compositions are Fa_13-42 and pyroxenes from Fs_12-25. This meteorite is an ordinary chondrite impact melt breccia, possibly an L chondrite.
