Writeup from AMN 14(1):
Sample No: LEW86347 Location: Lewis Cliff Field Number: 3395 Dimensions (cm): 1.5 x 0.8 x 0.7 Weight (g): 3.1 Meteorite Type: L3 chondrite
Macroscopic Description: Cecilia Satterwhite Ninety percent of the exterior of the sample is covered with weathered fusion crust. Abundant 1-2 mm sized inclusions are still visible in the extremely weathered interior.
Thin Section (,2) Description: Brian Mason The section shows numerous chondrules, up to 2.4 mm across, in a granular matrix consisting largely of olivine and pyroxene with minor amounts of nickel-iron and troilite. Most of the chondrules consist of granular or porphyritic olivine and olivine-pyroxene, but some radiating pyroxene chondrules were noted. The meteorite is considerably weathered, with brown limonite pervading the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-21, mean Fa15 (CV FeO is 36); pyroxene, Fs2-17. The small amount of nickel-iron suggests L group, and the variability of olivine and pyroxene compositions type 3, hence the meteorite is classified as an L3 chondrite (estimated L3.6).
