Writeup from AMN 19(1):
Sample No.: EET92093 Location: Elephant Moraine Dimensions (cm): 0.8 x 0.7 x 0.3 Weight (g): 0.4 Meteorite Type: E6 chondrite
Macroscopic Description: Cecilia Satterwhite Exterior of this small sample is dull brown and retains one small patch of black fusion crust. Chipping this meteorite revealed a dark brown interior with visible metal. EET92093 is friable and crumbles easily.
Thin Section (,2) Description: Brian Mason The section is very small (3 mm square) and is heavily stained with brown limonite. Only vague traces of chondritic structure are visible; the meteorite consists largely of granular enstatite with -20% nickel-iron and minor amounts of sulfides. The enstatite is almost pure MgSiO3 (CaO 0.1-0.2%; FsO 0.2-0.5%). Six metal grains were analyzed; three contained 2.8% Si, three 0.3% Si. Minor amounts of SiO2 polymorph are present, probably tridymite. The meteorite is classified as an E6 meteorite.
