Writeup from AMN 14(2):
Sample No.: LEW88596 Location: Lewis Cliff Field Number: 5322 Dimensions (cm): 2.3 x 2.1 x 0.5 Weight (g): 8.9 Meteorite Type: LL3 chondrite
Macroscopic Description: Cecilia Satterwhite Seventy-five percent of this chondrite is covered by fusion crust. Chipping this sample revealed a dark brown to black interior with some rusty areas. Evaporite deposit was noted. Light gray and cream colored inclusions/chondrules are present.
Thin Section (,2) Description: Brian Mason The section shows a close-packed aggregate of chondrules and chondrule fragments, up to 1.2 mm across, in a black opaque groundmass which contains a little nickel-iron and troilite. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa2-38, mean Fa13 (CV FeO is 65); pyroxene, Fs1-18. The variability of olivine and pyroxene compositions indicates type 3, and the small amount of nickel-iron LL group, hence the meteorite is classified as an LL3 chondrite (estimated LL3.4).
