Sample No.:
QUE93744
Location: Queen Alexandra Range
Dimensions (cm): 2.0 x 1.6 x 1.0
Weight (g): 7.7
Meteorite Type: CV3 Chondrite
Macroscopic Description: Cecilia Satterwhite
This carbonaceous chondrite has 50% of its exterior covered with frothy black fusion crust. Some rust-colored areas are visible on the exterior. The interior is dark-brown to black in color, fine-grained with abundant oxidation scattered throughout. Some small light-gray inclusions are visible.

Thin Section (,2) Description: Brian Mason
The section shows numerous chondrules and irregular aggregates, up to 1.5 mm across, in a black matrix. The matrix contains accessory amounts of nickel-iron and troilite. Microprobe analyses show that most of the olivine in the chondrules is close to Mg2SiO4 in composition, but ranges up to Fa10; pyroxene composition is Fs1-2. 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 and 93639, with which it is probably paired.
