Writeup from AMN 18(2):
Sample No.: QUE93018
Location: Queen Alexandra Range
Dimensions (cm):   1.5 x 1.1 x 0.8
Weight (g): 1.3
Meteorite Type: C2 Chondrite
    QUE93018 sample

Macroscopic Description: Robbie Marlow
The exterior of this carbonaceous chondrite has patches of dull black fusion crust. Areas devoid of fusion crust are dull black and porous. The interior matrix is black and fine grained. One millimeter-sized dark clast is visible.

Thin Section (,2) Description: Brian Mason
The section shows rare chondrules up to 0.5 mm across, and numerous small silicate grains in a dark brown to black matrix. Most of the chondrules have been converted into brown serpentine. Trace amounts of nickel-iron and troilite are present as minute grains. Olivine is near Mg2SiO4 in composition, with a few more iron-rich grains. The matrix appears to consist largely of iron-rich serpentine. The meteorite is a C2 chondrite; it is very similar to QUE93005, with which it is probably paired.
