Sample No.: QUE93005
Location: Queen Alexandra Range
Dimensions (cm): 3.5 x 1.7 x 1.9
Weight (g): 13.4
Meteorite Type: C2 chondrite
Macroscopic Description: Robbie Marlow
QUE93005 has dull black fusion crust covering 90% of its exterior. Flow marks are present on all surfaces. Cleaving this specimen revealed a fine-grained, grayish-black interior. Evaporite deposit is present immediately underneath the fusion crust.
Thin Section (,2) Description: Brian Mason
The section shows a few chondrules, up to 0.7 mm across, and numerous small mineral grains in a dark brown to black matrix. Some chondrules consist of granular or porphyritic olivine, but most have been converted to brown serpentine. Fusion crust is present along one edge. Olivine is near Mg2SiO4 in composition, with a few more iron-rich grains. Many of the small mineral grains consist of calcite or ferroan dolomite. The matrix appears to consist largely of iron-rich serpentine. The meteorite is a C2 chondrite.
