| Macroscopic Description - Cecilia Satterwhite |

| Thin Section
(,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach |
| The section shows an aggregate of chondrules (up to 2 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide. Chondrules contain moderate to small abundances of olivine. Weathering is modest, with staining of some enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show the olivine is Fa1 and pyroxene is Fs1-4. Metal contains ~2.5 wt% Si. The meteorite is an EH3 chondrite. |
