Sample No.:QUE94734
Location:Queen Alexandra Range
Dimensions (cm):3.0 x 2.1 x 2.0
Weight (g):11.17
Meteorite Type:C2 Chondrite

Macroscopic Description: Cecilia E. Satterwhite

Fifty percent of the exterior of this carbonaceous chondrite is covered with fractured black fusion crust. Flow lines are present on the fusion crust on some surfaces. Areas without fusion crust are dull and brownish gray in color. The interior reveals a black fine grained matrix with mm-sized gray inclusions.

Thin Section (,2) Description: Brian Mason

The section shows sparse chondrules, up to 0.9 mm across, some irregular aggregates, and numerous small silicate grains in a dark brown to black matrix. The silicate grains are almost entirely olivine near Mg2SiO4 in composition, with a few more iron-rich grains. A little pyroxene near MgSiO3 in composition is present. The matrix appears to consist largely of iron-rich serpentine. The meteorite is a C2 chondrite.
