Macroscopic Description - Kathleen McBride
This disk shaped meteorite is flat on the bottom and has thick black crust with bubbles around the edges. Evaporites are visible along the top and central bottom faces. The interior is black and white and has no visible inclusions or chondrules.
Thin Section Description (,3) - Cari Corrigan and Linda Welzenbach
The section shows few chondrules (up to 0.5 mm), chondrule fragments, and pyroxene grains in a matrix with about 30% metal and sulfide. The matrix has been extensively recrystallized. Weathering is modest, with staining of some enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show pyroxene compositions of Fs0-1Wo0-3. Si in the metal is 0.23 wt. %. The meteorite is a type 6 enstatite chondrite, probably an EL6
