Macroscopic Description - Kathleen McBride | |
This enstatite chondrite has no fusion crust on the exterior. The interior is gray with some rust and a black vein. Some gray chondrules are visible. | |
Thin Section Description (,2) - Linda Welzenbach, Pamela Salyer, Tim McCoy | |
No traces of chondritic structure are visible in the thin section, which shows the meteorite to consist largely of comminuted or granular enstatite (grain size 0.1-0.2 mm), a considerable amount of nickel-iron, and minor amounts of sulfides and plagioclase. The meteorite is mildly weathered. Microprobe analyses show that the enstatite is almost pure MgSiO3 (FeO 0.1-0.3%); on average, the nickel-iron contains 0.9% Si. The meteorite is an EL6 chondrite. |
