Macroscopic Description - Kathleen McBride
<5% of the surface is covered with small black patches of fusion crust with evaporites. The black fine grained interior has tan to white weathering products along the exterior edge. There is rusting in some areas and green alteration zones along fractures. The meteorite is very hard and dense.
Thin Section (,2) Description - Cari Corrigan, Linda Welzenbach and Nicole Lunning
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. Weathering is moderate, with staining of some enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show pyroxenes of composition Fs0-3Wo0-1 and 1.8 wt% Si in the metal. The meteorite is an enstatite chondrite, EL6.
