Writeup from AMN 14(2):
Sample No.: LEW88367 Location: Lewis Cliff Field Number: 4525 Dimensions (cm): 3 x 2 x 1.8 Weight (g): 14.0 Meteorite Type: H3 chondrite
Macroscopic Description: Robbie Marlow Regmaglypts are present in the dark brown fusion crust which covers 90% of this meteorite. Numerous millimeter sized chondrules/inclusions were noted in the weathered matrix. Evaporite deposit is present on the interior material.
Thin Section (,2) Description: Brian Mason The section shows numerous chondrules and chondrule fragments, up to 1.8 mm across, in a finely granular matrix of olivine and pyroxene which contains a moderate amount of nickel-iron and troilite. Weathering is extensive, with brown limonitic staining throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa14-22, mean Fa19 (CV FeO is 11); pyroxene, Fs4-25. The amount of nickel-iron suggests H group, and the variability of olivine and pyroxene compositions type 3, hence the meteorite is classified as an H3 chondrite (estimated H3.8).
