Name: Elephant Moraine 92103 This is an OFFICIAL meteorite name. Abbreviation: EET 92103 Observed fall: No Year found: 1992 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 1.5 g
Sample No.: EET92103
Location: Elephant Moraine
Dimensions (cm): 1.5 x 1.2 x 0.6
Weight (g): 1.5
Meteorite Type: C2 chondrite
Macroscopic Description: Robbie Marlow
Sixty percent of the exterior of EET92103 is covered with dull black fusion crust. The fusion crust is fractured and contains small amounts of evaporite deposit. The interior material is fine-grained with numerous white inclusions that are sub-millimeter in size. Weathering is minimal.
Thin Section (,3) Description: Brian Mason
The section shows small chondrules (up to 0.5 mm across) and occasional mineral grains in a semi-translucent dark brown to black matrix. Most of the chondrules and mineral grains consist of olivine; pyroxene is rare. Microprobe analyses show that most of the olivine is close to Mg2SiO4 in composition, with a few more iron-rich grains; one pyroxene grain, Fs3, was analyzed. The matrix appears to consist largely of iron-rich serpentine. The meteorite is a C2 chondrite.
