Macroscopic Description: Cecilia Satterwhite Shiny black fusion crust covers 95% of this meteorite. Abundant inclusions/chondrules are present in the dark brown matrix.
Thin Section (,2) Description: Brian Mason The section shows abundant chondrules and chondrule fragments, up to 2.1 mm across, in a fine-grained matrix of olivine and pyroxene and a little nickel-iron and troilite. Brown limonitic staining and small areas of limonite are present throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa6-22, mean Fa13 (CV FeO is 37); pyroxene, Fs3-14. The variability of olivine and pyroxene compositions indicate type 3, and the amount of nickel-iron LL group, hence the meteorite is classified as an LL3 chondrite (estimated LL3.6).
