Macroscopic Description - Roger Harrington
The exterior of this meteorite has black patches of fusion crust. Areas without fusion crust are rusty brown. Half of the interior is a gray matrix with some oxidation and the other half consists of metal.
Thin Section Description (,7) - Tim McCoy
The section examined included two pieces, each ~5 mm in maximum dimension. One piece is comprised dominantly of silicate and is typical of an equilibrated L chondrite. Metal and sulfide exhibit evidence of shock melting, including fizzed texture and shock blackening with trails of metal and/or sulfide. The other piece is >99% metal and includes kamacite and taenite. Silicate inclusions include fragmental pieces of chondritic material and micromelted silicate inclusions with a cellular texture. The meteorite is a shocked L chondrite containing an unusually large metal particle.
Reclassification Notes (AMN 37,2)
Reclassified as a shocked L Chondrite.
