| The cpx is classified as augite based on average composition, and displays a very narrow compositional range. |
| The volcanics were described by Aghabawa as alkaline basalts, hawaiites and mugearites with plagioclase, olivine and augite as the essential constituents. |
| The most common phenocryst silicate phases are olivine, plagioclase and augite, typically, although not always, appearing in that order. |
| Thus the order of phenocryst appearance in Kilauea lavas is olivine, plagioclase, augite whereas in Mauna Loa lavas it is olivine, augite, plagioclase. |
| Normal alkali basalt contains olivine and, commonly, a diopsidic or titaniferous augite. |
| It was found to contain good crystals of augite and olivine, well striated labradorite, and titaniferous iron ore. |
