Sample No.: MIL 05050
Location: Miller Range
Field No.: 18758
Dimensions (cm):   8.5x5.5x4.0
Weight (g): 253.3
Meteorite Type: L3 Chondrite


Macroscopic Description: Kathleen McBride
85% of this ordinary chondrites exterior has rough brown/black fusion crust with polygonal fractures. The interior is a black matrix with abundant chondrules of various sizes and colors.


Thin Section (,2) Description: Tim McCoy
The section exhibits numerous small, well-defined chondrules (up to 1.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Silicates are unequilibrated; olivines range from Fa6-25 and pyroxenes are Fs3-17. The meteorite is an L3 chondrite (estimated subtype 3.6).
