Sample No.: MIL 05139

Field No.: 18161
Dimensions (cm):   3.0x2.0x1.25
Weight (g): 10.603
Meteorite Type: EH3 Chondrite


Macroscopic Description: Kathleen McBride
50% of the exterior has smooth brown/black fusion crust. The interior is a rusty brown color that is very weathered and crumbles easily.


Thin Section (,2) Description: Tim McCoy
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. Microprobe analyses show the olivine is Fa2 and pyroxene is Fs0-3. Metal contains ~0.6 wt. % Si. The meteorite is a type 3 enstatite chondrite, probably an EH3.
