Writeup from AMN 24(2):
Sample No.: QUE 99113
Location: Queen Alexandra Range
Field No.: 12111
Dimensions (cm):   1.5x1.0x0.5
Weight (g): 0.576
Meteorite Type: CM2 Chondrite

Macroscopic Description: Kathleen McBride
Dull, black fusion crust covers 20% of the exterior of this carbonaceous chondrite. The interior is a dark gray to black matrix with millimeter sized white and light gray inclusions.

Thin Section (,3) Description: Tim McCoy and Linda Welzenbach
QUE 99113 - Plane-Polarized Light The section measures 8x5 mm. Vesicular fusion crust comprises ~80% of the section. Unaltered material is relatively rare. A few large chondrules are present at one end, although no unaltered matrix may remain. Olivine compositions are Fa3-13, with most less than Fa4, and orthopyroxene is Fs2-13. The meteorite is a CM2 chondrite. It is possible that it is spalled off of a larger mass in flight, explaining the abundance of fusion crust.
