Writeup from AMN 10(2):

Sample No.: LEW86006

Location: Lewis Cliff

Weight (g): 0.8

Field No.: 3478

Dimensions (cm): 1.0 x 0.5 x 0.5

Meteorite Type: C3V Chondrite

 

Macroscopic Description: Roberta Score,

Forty percent of LEW86006 is covered by dull black fusion crust. Dark gray matrix with some irregularly shaped white inclusions makes up the interior of this stone. Oxidation is apparent.

 

Thin Section (,3) Description: Brian Mason

This very small section (5 x 3 mm) shows several chondrules, up to 1.5 mm across, and some irregular granular aggregates in a very fine-grained translucent brown matrix. The chondrules consist mainly of olivine, some with polysynthetically twinned clinopyroxene. Fusion crust is present along one edge. Microprobe analyses give olivine compositions ranging from Fa0 to Fa27, with a mean of Fa6; pyroxene compositions range from Fs0 to Fs5. The matrix appears to consist largely of fine-grained iron-rich olivine (Fa40-50). The meteorite is tentatively identified as a C3V chondrite.
