20998-14 - NWA Possible Achondrite Meteorite Porphyritic Basalt. In study. 233g Native copper WeberopeltisPetrographic description Under petrographic microscope, the sample is formed by phenocrysts mostly of olivine, clinopyroxene, plagioclase and in a smaller proportion quartz and orthopyroxene in a fine matrix (Figs. 2 and 3). The texture is porphyritic. Amygdules are scarce in the sample and are filled by calcite. The olivine grains are embayed and partially reabsorbed. Pyroxene crystals show complex zoning patterns, range from concentric to patchy.
