Sample No.: EET92063

Location: Elephant Moraine

Dimensions (cm): 4.6 x 3.6 x 2.0

Weight (g): 74.6

Meteorite Type: E6 chondrite

 

Macroscopic Description: Robbie Marlow

EET92063 has dull, dark brown fusion crust that covers over 90% of its exterior. The interior matrix is a deep red-brown color and coarse-grained. Heavy oxidation has masked any features that might be present.

 

Thin Section (,2) Description: Brian Masort

Only vague traces of chondritic structure are visible in the thin section which shows the meteorite to consist largely of granular to prismatic enstatite (grain size 0.1-0.2 mm), a considerable amount of nickel-iron (~20%) and minor amounts of sulfides. Remnants of fusion crust rim the section. Considerable weathering is indicated by brown limonitic staining throughout the section. The enstatite is almost pure MgSiO3 (CaO 0.7%; FeO 0.2-0.4%); the metal contains 1.2% Si. The meteorite is an E6 chondrite.
