Sample No.: LEW88696 Location: Lewis Cliff Field Number: 6144 Dimensions (cm): 2.1 x 1.8 x 1.0 Weight (g): 6.0 Meteorite Type: L3 chondrite
Macroscopic Description: Robbie Marlow, Ninety percent of LEW88696 is covered with smooth brown fusion crust. Abundant millimeter-sized inclusions are visible in the gray matrix. Oxidation appears as large patches scattered throughout the interior.
Thin Section (,2) Description: Brian Mason The section shows numerous chondrules and chondrule fragments, up to 2.4 mm across, in a groundmass of fine-grained olivine and pyroxene with a minor amount of nickel-iron and troilite. Weathering is extensive, with limonitic staining and small areas of red-brown limonite throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa5-19, mean Fa16 (CV FeO is 28); pyroxene, Fs6-19. 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 L3.7).
