Location: Queen Alexandra Range
Dimensions (cm): 2.0 x 1.5 x 1.5
Weight (g): 7.4
Meteorite Type: E5 chondrite

Macroscopic Description: Carol Schwarz
Approximately 50% thin, shiny, and iridescent fusion crust remains on the exterior of QUE93372. The interior matrix has areas of white/rusty material and medium gray material. Metal is dense in the gray areas but less concentrated in the white and rusty areas. Weathering is moderate.

Thin Section (,2) Description: Brian Mason
The section shows a granular aggregate of pyroxene, with considerable nickel-iron and minor sulfides. A few chondrules can be recognized, but their margins are largely integrated with the matrix. The meteorite is moderately weathered, with some limonitic staining throughout the section. Microprobe analyses show that the pyroxene is essentially pure MgSiO3; the metal contains 2.7% Si. The meteorite is classified as an E5 chondrite.
