Writeup from AMN 13(3):
Sample No. LEW88033 Location: Lewis Cliff Dimensions (cm): 1 x 1.1 x 0.7 Field Number: 4156 Weight (g): 1.9 Meteorite Type: L3 chondrite
Macroscopic Description: Carol Schwarz Dull fusion crust covers ~90% of the exterior of LEW88033 and one surface has a frothy texture. Abundant small inclusions (1 mm) are obvious in the dark gray matrix. Oxidation is moderate.
Thin Section (,2) Description: Brian Mason The section shows numerous chondrules and chondrule fragments, up to 1.8 mm across, in a small amount of dark fine-grained matrix. A little metal and sulfide is present, concentrated as black rims to the chondrules. Most of the chondrules are porphyritic or granular olivine and olivine-pyroxene, but fine-grained to cryptocrystalline pyroxene chondrules are also present. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-32 (CV FeO is 77); pyroxene, Fs2-19. The small amount of metal indicates L group, and the variability of olivine and pyroxene compositions type 3, hence the meteorite is classified as an L3 chondrite (estimated L3.3).
