Macroscopic Description - Rachel Funk | |
This exterior of this fractured meteorite has 30% brown fusion crust. The exposed surface is brown with red/orange rust. The interior is a black/brown matrix full of orange rust and metal. | |
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 Fa13-42 and pyroxenes from Fs12-25. This meteorite is an ordinary chondrite impact melt breccia, possibly an L chondrite. |
