Sample No.: LEW88467 Location: Lewis Cliff Field Number: 5253 Dimensions (cm): 1.6 x 1.5 x 1.4 Weight (g): 6.6 Meteorite Type: L3 chondrite
Macroscopic Description: Robbie Marlow Eighty percent of the exterior of this friable unequilibrated chondrite is covered with dull black, pitted fusion crust. The interior is medium gray with abundant chondrules.
Thin Section (,2) Description: Brian Mason The section shows chondrules and chondrule fragments, up to 2.8 mm across, in a finely granular matrix of olivine and pyroxene with minor troilite and nickel-iron. Minor weathering is indicated by limonitic staining associated with metal grains Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa6-15, mean Fa12 (CV FeO is 16); pyroxene, Fs3-15. The 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 L3.8).
