Sample No.: EET83250

Location: Elephant Moraine

Weight (g): 11.5

Field No.: 1441

Dimensions (cm): <2

Meteorite Type: C2 Chondrite

Macroscopic Description: Roberta Score

When EET83250 was first removed from its container, it existed in many pieces that could not be reassembled. It is, however, possible to distinguish between the exterior (many pieces containing fusion crust and evaporite deposit) and the interior surfaces, which are black with speckles of white inclusions. Rust spots and some evaporite deposits are visible on some of the interior pieces.

Thin Section (,3) Description: Brian Mason

Only a few chondrules and chondrule fragments are present; the bulk of the meteorite consists of brown to black semi-opaque matrix, enclosing numerous small (0.1-mm and less) colorless birefringent grains, mostly olivine. The matrix also contains trace amounts of finely dispersed nickel-iron and sulfides. Well-preserved fusion crust rims part of the section. Microprobe analyses show most of the olivine close to forsterite in composition, with a few iron-rich grains (Fa0.3 - Fa22), mean Fa4). Pyroxene grains are rare; composition range is Fs2 - Fs14. The meteorite is a C2 chondrite.
