Sample No. LEW88007 Location: Lewis Cliff Dimensions (cm): 2.6x2x1.5 Field Number: 4610 Weight (g): 8.4 Meteorite Type: Monomict Eucrite
Macroscopic Description: Robbie Marlow Seventy-five percent of the exterior of this achondrite is covered with shiny and dull fusion crust. The interior shows an even distribution of mafic and nonmafic minerals. No individual clasts were noted. Small areas of oxidation are present.
Thin Section (,5) Description: Brian Mason, The section shows an ophitic intergrowth of pigeonite and plagioclase, with trace amounts of opaque minerals. The grain size and texture vary considerably within the section, suggesting a recrystallized breccia. Microprobe analyses show pyroxene ranging in composition from Wo2Fs60 to Wo40Fs26, with relatively uniform En content. Plagioclase ranges in composition from An85 to An91, with a mean of An90. The meteorite is a monomict eucrite.
