Sample No.: LEW88632

Location: Lewis Cliff

Field Number: 6115

Dimensions (cm): 2.5 x 1.5 x 1.3

Weight (g): 10.3

Meteorite Type: L3 chondrite

Macroscopic Description: Cecilia Satterwhite

This weathered chondrite has 80% of its exterior covered with fusion crust. The dark brown interior contains numerous chondrules. Some metal is still obvious.

Thin Section (,2) Description: Brian Mason

The section shows a close-packed aggregate of chondrules and chondrule fragments, up to 1.8 mm across, in a fine-grained matrix of olivine and pyroxene with minor amounts of nickel-iron and troilite. Brown limonitic staining pervades the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa2-21, mean Fa12 (CV FeO is 37); pyroxene, Fs8-23. The variability of olivine and pyroxene compositions indicates type 3, and the amount of nickel-iron L group, hence the meteorite is classified as an L3 chondrite (estimated L3.6).
