Sample No.: LEW86003 Location: Lewis Cliff Weight (g): 1.6 Field No.: 3426 Dimensions (cm): 1.5 x 1.0 x 0.5 Meteorite Type: Eucrite (Brecciated)
Macroscopic Description: Roberta Score LEW86003 is mostly covered with dull black fusion crust. Ninety percent of the interior has a basaltic texture; is light gray in color with minor black inclusions. Ten percent of the interior is jet black. This area contains minor inclusions and is more oxidized than the lighter material. There is a sharp contact between these two areas.
Thin Section (,3) Description: Brian Mason Most of the section is an ophitic intergrowth of pyroxene and plagioclase, the plagioclase laths up to 0.9 mm long; one end is sharply bounded by an area of subophitic to gabbroic clasts, up to 1.8 mm across, in a dark brown glassy matrix. Mineral compositions are similar throughout. Pyroxene compositions range from Wo2Fs64 to Wo43Fs27, with fairly uniform En contents; plagioclase compositions are An67-91. The meteorite is a brecciated eucrite. | ||||||||||||||||||||
