augite's Usage Examples:

yellow-green olivine phenocrysts (20-50%) and black to dark brown pyroxene, mostly augite.

They contain augite and olivine crystals.

alteration of augite (biotite or hornblende) to chlorite, and is seen in many diabases, diorites and greenstones.

breccia that has a porphyritic appearance, consisting of plagioclase (andesine) and pyroxene (pigeonite and augite) phenocrysts that are up to 5 mm in.

The clinopyroxene is sodic whose composition varies from hedenbergite to aegirine-augite.

Their pyroxene is principally aegirine or aegirine-augite; some of them are rich in melanite.

The calcium content of augite is limited by a miscibility gap between it and pigeonite and orthopyroxene: when occurring with either.

augite, biotite, diopside, haüyne, iron-titanium oxides, leucite, nepheline, nosean, pyrite, sanidine, sodalite and titanite.

characteristic of the phonolites may also be found in some trachytes; thus aegirine or aegirine augite forms outgrowths on diopside crystals, and riebeckite may.

trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass.

plagioclase set in a groundmass of augite and more sodic plagioclase and perhaps analcite and biotite.

In the aegirine-augite series the sodium.

relative to other basalts and by the presence of olivine and titanium-rich augite in its groundmass and phenocrysts, and nepheline in its CIPW norm.
