Sample No.: LEW85353 Location: Lewis Cliff Weight (g): 24.5 Field No.: 3188 Dimensions (cm): 4x2x2 Meteorite Type: Eucrite
Macroscopic Description: René Martinez This pebble retains most of its thin fusion crust. Weathering of the stone has removed some fusion crust and left a pitted surface. The interior is light gray and has a basaltic texture.
Thin Section (,3) Description: Brian Mason The section shows a fine-grained aggregate (grains 0.1-0.4 mm) of pale brown pyroxene and colorless plagioclase, with a few opaque grains. Minor weathering is indicated by brown limonitic staining around opaque grains. Plagioclase is fairly uniform in composition, mean Anal. Pyroxene is largely hypersthene of mean composition Wo2Fs60, together with some augite, Wo48Fs22; the augite shows exsolution lamellae of hypersthene. The meteorite is an unbrecciated eucrite. | ||||||||||||||||||||||||
