Writeup from AMN 14(2):
Sample No.: LEW88520 Location: Lewis Cliff Field Number: 5383 Dimensions (cm): 1.9 x 1.2 x 1 Weight (g): 3.1 Meteorite Type: L3 chondrite
Macroscopic Description: Robbie Marlow Dark brown fusion crust covers almost half of this weathered meteorite. Although the interior is extremely weathered, some millimeter sized inclusions/chondrules are visible.
Thin Section (,2) Description: Brian Mason The section shows a close-packed aggregate of chondrules and chondrule fragments, up to 2.4 mm across, in a matrix of fine-grained olivine and pyroxene and a little nickel-iron and troilite. Brown limonitic staining pervades the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa4-24, mean Fa14 (CV FeO is 41); pyroxene, Fs2-17. The variability of olivine and pyroxene compositions indicated type 3, and the amount of nickel-iron suggests L group, hence the meteorite is classified as an L3 chondrite (estimated L3.5).
