Sample No.: EET83226

Location: Elephant Moraine

Weight (g): 33.1

Field No.: 1332

Dimensions (cm): 4 x 2.5 x 3

Meteorite Type: C2 Chondrite

Macroscopic Description: Roberta Score

No fusion crust remains on this angular carbonaceous chondrite. The exterior has a granular texture with chondrules and inclusions abundant. Interior surfaces are blackish-brown in color whereas the exterior surfaces are black.

Thin Section (,5) Description: Brian Mason

The section shows abundant small chondrules, averaging about 0.3 mm in diameter, and numerous enclaves and mineral grains set in a moderate amount of dark brown to black opaque matrix. Chondrule types include granular and barred olivine and pale brown partly devitrified glass. Accessory amounts of finely dispersed nickel-iron and sulfide are present. Microprobe analyses show that much of the olivine is of forsteritic composition, but occasional iron-rich grains are present (Fa0.5 - Fa69, mean Fa12). Pyroxene grains are rare; composition range is Fs0.6 - Fs10. The meteorite is classed as a C2 chondrite.
