Macroscopic Description - Cari Corrigan, Linda Welzenbach | |
This amoeboid-shaped meteorite is finely pitted over the entire surface. Fine flow lines are visible along prominent edges. Fusion crust is 80-90% and exhibits mild oxidation in the form of iridescence and minor halos. Fractures occur in several places over the surface and cross cut some of the lobes. | |
Thin Section Description - Tim McCoy, Cari Corrigan, Linda Welzenbach | |
The meteorite was examined from a cut and etched surface, which bisected one of the three distinct lobes of the specimen. Fusion crust reaching up to 0.4 mm in thickness is preserved over half the meteorite and a prominent fine a2 structure is present throughout. Short kamacite lamellae exceed 2 mm in width and are separated by thin (~100 micron wide) ribbons of taenite, which are often replaced by hydrated iron oxides of terrestrial origin. Many of the kamacite grains exhibit sub |
