Sample No.: EET83355

Location: Elephant Moraine

Weight (g): 66.2

Field No.: 2748

Dimensions (cm): 5.5 x 4 x 2.5

Meteorite Type: C2 Chondrite

Macroscopic Description: Roberta Score

Fusion crust covers 50% of this fragment. Areas devoid of fusion crust are polished and iridescent. White inclusions are scattered throughout the black matrix. Oxidation is present.

Thin Section (,2) Description: Brian Mason

The section shows numerous chondrules (up to 0.9 mm across) and irregular granular aggregates in a moderate amount of black opaque matrix. The matrix contains numerous small grains of nickel-iron and troilite. Most of the chondrules consist of granular olivine and olivine-pyroxene. Microprobe analyses show that much of the olivine is of forsteritic composition, but occasional iron-rich grains are present (up to Fa28, mean olivine composition is Fa6). Most of the pyroxene has composition in the range Fs0-1, but ranges up to Fs9. The meteorite is a C2 chondrite; the section resembles that of EET83226, and the possibility of pairing should be considered.
