Macroscopic Description - Mitchell Haller | |
85% of the fractured exterior has brownish red fusion crust with lighter brown spots. The interior is a reddish brown matrix with orange clasts, some metal is visible. | |
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Pamela Salyer | |
The section shows an aggregate of chondrules (up to 1 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 pyroxene is Fs0-1. The meteorite is a type 5 enstatite chondrite, probably an EL5. |
