Writeup from AMN 23(1):

Sample No.:	QUE 97416
Location:	Queen Alexandra Range
Dimensions (cm):	2.0x2.0x1.5
Weight (g):	12.272
Meteorite Type:	CO3 Chondrite (<3.2)

Macroscopic Description: Kathleen McBride
The exterior of this meteorite is brown with some weathered fusion crust. The interior is the color of mud with some tiny light colored inclusions.

Thin Section (, 2) Description: Tim McCoy
The section consists of abundant small (up to 1 mm) chondrules, chondrule fragments, and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa_1-50, with a continuous range of intermediate compositions and a slight peak at Fa_1-5. Two pyroxene analyses range from Fs_1-15. The matrix appears to consist largely of Fe-rich olivine. Terrestrial weathering effects are extensive. The meteorite is a CO3 chondrite. Comparison to the criteria of Scott and Jones (1990, GCA, Vol. 54, pp. 2485-2502) suggests a very low petrologic subtype (<3.2).
