Writeup from AMN 19(2):
Sample No.: QUE94688
Location: Queen Alexandra Range
Dimensions (cm): 2.2 x 1.8 x 1.1
Weight (g): 10.55
Meteorite Type: CV3 Chondrite
QUE94688

Macroscopic Description: Cecilia E. Satterwhite

Dull black fusion crust covers sixty percent of the exterior of this carbonaceous chondrite. The interior reveals a black fine grained matrix with some weathered inclusions. White mm-sized inclusions are abundant on the exterior and interior surfaces.

Thin Section (,2) Description: Brian Mason

The section shows numerous chondrules (up to 1.8 mm across), irregular aggregates, and mineral grains 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 olivine grains in the matrix are more iron-rich, ranging up to Fa33; pyroxene is rare, a single grain measured was Fs1. The matrix appears to consist largely of iron-rich olivine, about Fa45. The meteorite is classified as a C3 chondrite of the Vigarano subtype; it is very similar to QUE93429, and the possibility of pairing should be considered.
