| Original Classification |
Eucrite (Brecciated) |
| Macroscopic Description - Kathleen McBride |
| Black fusion crust that is shiny and ropey covers 15% of the exterior. Areas without fusion crust are a dirty gray color with large pinkish area and black and white inclusions. The interior looks the same as the exterior minus the fusion crust. |
| Thin Section
(,5) Description - Tim McCoy and Linda Welzenbach |
| The section is a breccia with mono- and polyminerallic clasts of pyroxene and plagioclase up to 1 mm in diameter in a fine-grained melt-textured matrix which is coarser-grained on one half of the section and cryptocrystalline on the other half. Pyroxene is finely exsolved, yielding pigeonitic compositions of Fs45-54Wo5-15 and plagioclase is An86-93Or0-1 The Fe/Mn ratio of the pyroxene is ~28. The meteorite is a eucritic impact melt breccia. |
