Sample No.: LEW88484 Location: Lewis Cliff Field Number: 5213 Dimensions (cm): 1.8 x 1.6 x 1.2 Weight (g): 8.4 Meteorite Type: LL3 chondrite
Macroscopic Description: Cecilia Satterwhite LEW88484 is a weathered specimen with 90% of its surface covered by fusion crust. The interior is brown in some areas and yellowish-gray in others. Inclusions are visible, as are metal blebs.
Thin Section (,2) Description: Brian Mason The section shows a close-packed aggregate of chondrules and chondrule fragments, up to 1.5 mm across, in a small amount of finely granular matrix which contains accessory amounts of nickel-iron and troilite. Weathering is extensive, with limonitic staining and areas of brown limonite throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa6-32, mean Fa22 (CV FeO is 32); pyroxene, Fs4-16. The small amount of nickel-iron suggests LL group, and the variability of olivine and pyroxene compositions type 3, hence the meteorite is classified as an LL3 chondrite estimated LL3.6).
