| Original Classification |
EL4 Chondrite |
| Macroscopic Description - Kathleen McBride |
| The exterior of 626 has thin black patches of fusion crust; 659 has no fusion crust. The interiors are a dense chocolate brown to black matrix with high metal and some weathered inclusions. |
| Thin Section
(,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach |
| The sections show an aggregate of chondrules (up to 1.5 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. Pyroxene is Fs0-2; no olivine grains were analyzed. Metal contains 0.5-0.6 wt% Si. The meteorites are type 4 enstatite chondrites. The Si concentration in metal would suggest classification as EL4. Pairing is tentative. |
