20999-59 - NWA Possible Achondrite Meteorite Porphyritic Basalt. In study. 192 g Invertebrates the serrations of the PaleocarcharodonPetrographic description Under petrographic microscope, the sample is a fine grained volcanic rock with olivine and pyroxene phenocrysts, surrounded by a fine grained matrix (Figs. 2 and 3). Phenocrysts show deformation, developing twins and cracks. Olivine grains have a thin rim (Figs. 2 and 3) of iddingsite (reddish border). Pyroxene is pale brown and presents some plagioclase inclusions. The matrix is formed by tabular euhedral plagioclase and
