Sample No.:
QUE93705
Location:Queen Alexandra Range
Dimensions (cm):3.8 x 3.4 2.0
Weight (g):55.0
Meteorite Type:L3 Chondrite (estimated L3.7)
Macroscopic Description: Cecilia Satterwhite
Ninety percent of the exterior of this L chondrite is covered with shiny, smooth, dark brown to black fusion crust. Areas devoid of fusion crust are weathered and have a rough texture. The interior is dark brown to black and fine-grained. Oxidation is scattered heavily throughout the sample. Some small weathered inclusions are visible.

Thin Section (,2) Description: Brian Mason
The section shows numerous chondrules (up to 1.8 mm across), chondrule fragments, and mineral grains in a small amount of black matrix. The matrix contains a small amount of nickel-iron and troilite. Weathering is extensive, with brown limonitic staining throughout the section. Microprobe analyses shows a considerable range in olivine and pyroxene compositions: olivine, Fa6-19, mean Fa14; pyroxene, Fs2-19. The meteorite is classified as an L3 chondrite (estimated L3.7).
