Location: Lewis Cliff

Field No.: 3486; 3278; 3214; 3239; 3210

Weight (g): 2.1; 4.7; 1.6; 5.6; 6.5

Dimensions (cm): 1.5 x 1.5 x 1.0; 2 x 1.5 x 1.5; 1.5 x 1.5 x 0.5; 2 x 1.5 x 1; 2 x 1.5 x 1.5

Meteorite Type: C2 Chondrite

Macroscopic Description: Roberta Score

Some fusion crust remains on each of these otherwise brownish and black stones. White evaporite deposit speckles the fusion crust-free exterior surfaces of LEW86005 and LEW86007. Some of the deposits have a metallic look to them. The brownish weathering rind extends 1 to 2 mm into the interior of LEW86004, LEW86008 and LEW86009. The interior matrix is jet black and contains abundant rounded and irregular shaped inclusions. The largest inclusion exposed is 2 mm in diameter.

Thin Section (LEW86004,3; LEW86005,2; LEW86007,2; LEW86008,3; LEW86009,4) Description: Brian Mason

These specimens are so similar that a single description is adequate. The sections show numerous small colorless grains, mainly olivine, irregular aggregates, and rare chondrules in an opaque to translucent brown matrix. Microprobe analyses of the olivines show a composition range of Fa0-54, with a marked peak at Fa0-1. A few grains of clinoenstatite were analysed, with composition range Fs0-7. The meteorites are C2 chondrites, and the possibility of pairing should be considered.
