Sample No.: LEW88594 Location: Lewis Cliff Field Number: 5306 Dimensions (cm): 2 x 2 x 0.5 Weight (g): 5.4 Meteorite Type: L3 chondrite
Macroscopic Description: Cecilia Satterwhite, Minor amounts of fusion crust remain on this extensively weathered meteorite. The interior matrix is brown to black with a few weathered inclusions. Some metal is present.
Thin Section (,2) Description: Brian Mason The section shows a close-packed aggregate of chondrules and chondrule fragments, up to 3 mm across, in a small amount of black matrix containing a little nickel-iron and troilite. Minor weathering is indicated by limonitic staining around metal grains. Microprobe analyses show olivine and pyroxene of variable compositions: olivine, Fa6-28, mean Fa22 (CV FeO is 22); pyroxene, Fs10-21 The variability of olivine and pyroxene compositions indicates type 3, and the small amount of nickel-iron L group, hence the meteorite is classified as an L3 chondrite (estimated L3.7).
