Sample Number MIL 090320
Newsletter 34,1
Location Miller Range
Field Number 20514
Dimensions 2.5 x 0.75 x 0.75
Weight 3.64
Original Classification EL6 Chondrite
Mineral Composition (%Fa &  %Fs)
Ferrosilite (mol%): 0.3

Macroscopic Description - Kathleen McBride
20% of the exterior has brown/black fusion crust with polygonal fractures. The interior is a rusty brown with high metal.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
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 rare olivine grains. Weathering is moderate, with staining of some enstatite grains and minor alteration of metal and sulfides. This meteorite contains sinoite, Si2N2O. Microprobe analyses show pyroxenes of composition Fs0.3. The meteorite is an enstatite chondrite, probably an EL6.
