Name: Elephant Moraine 90986 This is an OFFICIAL meteorite name. Abbreviation: EET 90986 Observed fall: No Year found: 1990 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 1.2 g
Sample No.: EET90986
Location: Elephant Moraine
Dimensions (cm): 1.6 x 0.9 x 0.5
Weight (g): 1.2
Meteorite Type: C2 chondrite
Macroscopic Description: Cecilia Satterwhite
Black, frothy, pitted, and fractured fusion crust covers most of EET90986. The interior is made up of fine-grained, black matrix with a few shiny inclusions. This sample is extremely friable.
Thin Section (,2) Description: Brian Mason
The section shows chondrules and chondrule fragments, up to 0.9 mm across, and small scattered mineral grains, in a black matrix. The chondrules and chondrule fragments appear to be completely serpentinized. Most of the mineral grains are calcite. The matrix consists largely of iron-rich serpentine, made opaque by carbonaceous matter. The meteorite is a C2 chondrite; it is similar to EET90047 and the possibility of pairing should be considered.
