Sample No: LEW88477 Location: Lewis Cliff Field Number: 5281 Dimensions (cm): 3 x 1.9 x 1.1 Weight (g): 12.3 Meteorite Type LL3 Chondrite
Macroscopic Description; Robbie Marlow Dark brown fusion crust almost completely covers this meteorite. Heavy oxidation obscures any features that are present in the interior matrix.
Thin Section (,1) Description: Brian Mason The section shows a close-packed aggregate of chondrules and chondrule fragments, up to 2.4 mm across, surrounded by a small amount of black opaque matrix which contains a little troilite and nickel-iron. Minor weathering is indicated by patchy brown limonite in the matrix. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa4-20, mean Fa14 (CV FeO is 54); pyroxene, Fs4-20. The very small amount of nickel-iron suggests UL group, and the variability of olivine and pyroxene compositions type 3, hence the meteorite is classified as an LL3 chondrite (estimated LL3.4).
