Sample No.: EET92005; 92007; 92008, 92009, 92010 Location: Elephant Moraine Dimensions (cm): 2.8 x 2.0 x 1.0; 1.3 x 0.7 x 0.7; 1.7 x 1.3 x 0.8; 0.7 x 0.5 x 0.5; 3 fragments 1 x 0.5 x 0.5 each Weight (g): 5.4; 0.6; 1.5; 0.2; 1.0 Meteorite Type: C2 chondrite
Macrosc ooic Description: Carol Schwarz EET92005 and 92008 retain some frothy fusion crust; the other specimens have none. The exterior of 92008 has weathered to a dark green color typical for Antarctic carbonaceous chondrites. Its interior is black with rust-colored inclusions. All of the other specimens have dark gray to black colored matrices with numerous weathered, light colored, <1-mm sized inclusions. 92010 consists of three small fragments.
Thin Section (EET92005,2; 92007,2; 92008,2; 92009,2; 92010,2) Description: Brian Mason These sections are so similar that a single description will suffice; the meteorites are probably paired. The sections show a few chondrules, up to 0.9 mm across, irregular aggregates, and small mineral grains in a black matrix. The minerals are almost entirely olivine, near Mg2SiO4 in composition, with a few iron-rich grains. A small amount of pyroxene may be present. The meteorite is a C2 chondrite.
