Location: Queen Alexandra Range
Dimensions (cm): 1.8 x 1.0 x 0.6
Weight (g): 1.6
Meteorite Type: CV3 Chondrite
Macroscopic Description: Robbie Marlow
Ten percent of this meteorite is covered with frothy black patches of fusion crust. Trace amounts of evaporite deposit are visible on the exterior. The interior matrix is dark gray and fine grained with abundant white inclusions.

Thin Section (,2) Description: Brian Mason
The section shows numerous chondrules and irregular aggregates, up to 1.5 mm across, in a black matrix. A small amount of nickel-iron and troilite is present at the rims and within the chondrules. Microprobe analyses show that most of the olivine in the chondrules is close to Mg2SiO4 in composition, but ranges up to Fa17; pyroxene composition is Fs1-11. The matrix appears to consist largely of iron-rich olivine, about Fa50. The meteorite is classified as a C3 chondrite of the Vigarano subtype; it is very similar to QUE93429, with which it is probably paired.
