Sample No.: LEW88135 Location: Lewis Cliff Field Number: 4495 Dimensions (cm): 2.5 x 1.8 x 1.5 Weight (g): 16.0 Meteorite Type: E6 chondrite
Macroscopic Description: Cecilia Satterwhite Fractures penetrate the interior of this weathered chondrite. About half of the stone is covered by fusion crust. The interior is heavily oxidized but metal is still obvious. Evaporite deposit is present in the interior.
Thin Section (,2) Description: Brian Mason Chondritic structure is barely perceptible, the section showing an aggregate of small pyroxene grains, up to 0.2 mm across, with a little plagioclase and about 25% of metal and sulfide. Considerable weathering is indicated by the presence of veins and patches of brown limonite. Microprobe analyses show that the pyroxene is almost pure MgSiO3, with 1.0% CaO and up to 0.4% FeO; plagioclase composition is An18; the nickel-iron contains up to 1.1% Si. The meteorite is a E6 chondrite.
