Macroscopic Description - Cecilia Satterwhite

Most of exterior of this meteorite is weathered brown with some black pitted fusion crust. The interior is black matrix with brown weathered areas.

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

The section is dominated by a >1 cm region of shock melt which contains relict clasts and chondrules in a fine grained matrix with metal and sulfide blebs. A corner of the section is unmelted chondritic material of petrologic type 5 with relict chondrules. Olivines are Fa_11-31 and pyroxenes are Fs₂₅Wo₂. This meteorite is an ordinary chondrite impact melt breccia, probably an LL chondrite.
