Sample No: LEW88698

Location: Lewis Cliff

Field Number: 6112

Dimensions (cm): 0.4 x 0.5 x 0.8

Weight (g): 0.8

Meteorite Type: Metallic fragment from an iron or stony-iron meteorite.

Macroscopic Description: Rov S. Clarke. Jr.

This pea-shaped metallic mass is covered with a reddish brown weathering crust indicative of severe weathering.

Polished Section (,1): Roy S. Clarke..Jr.

A 137 mg median slice was removed for section preparation, leaving butts of 116 mg and 352 mg. The surface is bordered intermittently with terrestrial corrosion products. Within these corrosion layers are several small structures that appear to be remnant fusion crust. Several faint subgrain boundaries are present in the metal. Otherwise the surface consists of a uniform α2 structure that suggests strong heating of kamacite in the atmosphere. An electron microprobe traverse across the center of the surface revealed a uniform composition: 6.3 wt% Ni, 0.33 wt% Co, and 0.11 wt% P. This composition suggests a fragment from an iron or stony-iron parent body.
