21002-63 - NWA Possible Achondrite Meteorite Porphyritic Basalt. In study. 244.1 g Acanthopyge It has tiny glued andPetrographic description Under petrographic microscope, the sample is a fine grained volcanic rock with olivine and pyroxene euhedral phenocrysts, surrounded by fine grained matrix (Figs. 2 and 3). Olivine shows a thin rim (Figs. 2 and 3) of iddingsite (reddish border). The rock matrix is formed by tabular euhedral plagioclase and anhedral pyroxene crystals and, in a minor amount, by ilmenite grains. Tabular plagioclase crystals display certain
