Sample No.: LEW85420 Location: Lewis Cliff Weight (g): 12.4 Field No.: 3148 Dimensions (cm): 2.5 x 2 x 1.5 Meteorite Type: Brecciated L6 Chondrite
Macroscopic Description: René Martinez Smooth fusion crust covers all but one fracture surface. The interior is dark gray with few light colored inclusions present.
Thin Section (,3) Description: Brian Mason A few chondrule fragments are present, but most of the section consists of a finely granular aggregate of olivine and pyroxene; some of the pyroxene is polysynthetically twinned clinobronzite. Some fragments of barred olivine chondrules have transparent brown glass bars. Minor amounts of nickel-iron and troilite are present. Olivine and pyroxene are essentially uniform in composition: olivine. Fa24; pyroxene, Fs20. A little plagioclase, An10, was analysed. The meteorite is tentatively classified as an intensely brecciated L6 chondrite, containing fragments of L3-5 chondrites. | ||||||||||||||||||||
