Sample No. LEW86102; 86105

Location: Lewis Cliff

Dimensions (cm): 3.5 x 1.5 x 1.5; 1.5 x 1 x 1

Field Number: 3004; 3016

Weight (g): 21.8; 6.4

Meteorite Type: H3 chondrite

Macroscopic Description: Cecilia Satterwhite

Shiny smooth brown/black fusion crust completely covers both of these specimens. The interior consists of black matrix with abundant small weathered chondrules. Oxidation is scattered throughout the interior with LEW86105 being more weathered.

Thin Section (LEW86102,3; 86105,2) Description: Brian Mason

These sections are so similar that a single description will suffice; the meteorites are probably paired. Chondrules and chondrule fragments are abundant,, ranging up to 2.1 mm across; most are porphyritic or granular olivine and olivine-pyroxene, but a few radiating or cryptocrystalline pyroxene chondrules were noted. They are surrounded by a dark finely granular groundmass containing some metal and a little sulfide, often as rims to chondrules; the metal is extensively altered to limonite. Microprobe analyses show olivine and pyroxene of highly variable composition; olivine, Fa1-50 (CV FeO is 70); pyroxene, Fs1-41. The meteorites are tentatively classified as H3 chondrites (estimated H3.3).
