Sample No.: EET90102

Location: Elephant Moraine

Field Number: 6932

Dimensions (cm): 3 x 2 x 1.3

Weight (g): 17.0

Meteorite Type: E6 chondrite

Macroscopic Description: Carol Schwarz

This smooth oblong stone is completely covered with black to iridescent fusion crust. The interior is fine-grained and dark red-brown with abundant metal. Rusty evaporites are abundant in the freshly broken surface.

Thin Section (,2) Description: Brian Mason

Only vague traces of chondritic structure are visible in the thin section, which shows the meteorite to consist largely of granular enstatite (grain size 0.1-0.2 mm), a considerable amount of nickel-iron (-20%), and minor amounts of sulfides and plagioclase; traces of a highly birefringent colorless mineral, probably sinoite, are present. Remnants of fusion crust rim the section. Considerable weathering is indicated by areas of brown limonite throughout the section. Microprobe analyses show the enstatite is almost pure MgSiO3 (CaO 0.7%; FeO 0.2%; Al2O3, TiO2, and MnO each < 0.1%); plagioclase is somewhat variable in composition, An11-18. The metal contains 0.8% Si. The meteorite is an E6 chondrite.
