Sample No.: QUE93007
Location: Queen Alexandra Range
Dimensions (cm): 1.4 x 1.1 x 0.9
Weight (g): 3.1
Meteorite Type: CK5 chondrite

Macroscopic Description: Robbie Marlow
Dull black fusion crust covers 40% of the exterior of QUE93007. Traces of evaporite deposit are present. Several white, submillimeter-sized inclusions are visible in the dark gray, fine-grained matrix. This specimen is friable.

Thin Section (,3) Description: Brian Mason
The section shows sparse poorly-defined chondrules, up to 1.8 mm across, in a groundmass of fine-grained olivine with minor plagioclase and opaques (mainly magnetite, with some sulfide). Olivine has a uniform composition, Fa31; plagioclase composition is variable, An24-64; one grain of diopside, Wo42Fs17, was analyzed. The meteorite is a C5 of the Karoonda subtype.
