Name: Elephant Moraine 92126 This is an OFFICIAL meteorite name. Abbreviation: EET 92126 Observed fall: No Year found: 1992 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 4.8 g
Sample No.: EET92126 Location: Elephant Moraine Dimensions (cm): 2.4 x 1.3 x 0.6 Weight (g): 4.8 Meteorite Type: CO3 chondrite
Macroscopic Description: Cecilia Satterwhite Black, frothy fusion crust entirely covers this carbonaceous chondrite. The interior is made up of medium to coarse grained, grayish-brown matrix. A few small weathered inclusions are present as is a small amount of metal. Oxidation is evenly scattered throughout the specimen.
Thin Section (,2) Description: Brian Mason The section shows numerous small chondrules (up to 0.6 mm across), chondrule fragments, and mineral grains, in a black matrix containing minor amounts of nickel-iron and troilite concentrated around chondrule margins. Remnants of fusion crust rim part of the section. Microprobe analyses show much of the olivine near Mg2SiO4 in composition, but with individual grains ranging up to Fa51; a little Mg-rich pyroxene is present. The matrix appears to consist largely of iron-rich olivine. The meteorite is classified as a C3 chondrite of the Ornans subtype.
