• Faujasite occurs in vesicles within basalt and phonolite lava and tuff as an alteration or authigenic mineral. It occurs with other zeolites, olivine, augite and nepheline.
• The main components are plagioclase and augite, usually fresh, non-altered.
• The name "picrite" can also be applied to an olivine-rich alkali basalt: such picrite consists largely of phenocrysts of olivine and titanium-rich augite pyroxene with minor plagioclase set in a groundmass of augite and more sodic plagioclase and perhaps analcite and biotite.
• The diabase is typically dark gray to black, dense, and fine grained, consisting of predominately labradorite and augite.
• The less evolved alkali rocks tend to contain phenocrysts of olivine, and almost all have augite phenocrysts with elevated titanium, aluminum, and sodium compared with the calcic augite phenocrysts of tholeiites.

• The Alphard Tertiary Igneous Province includes Palaeocene tuffs, trachybasalts, aegirine–augite trachytes and aegirine–augite phonolitic trachytes, which have been radiometrically dated at about 58 million years old.
• Old Pariou is trachytic and trachybasaltic. These are black rocks and contain small augite, anorthite (bytownite and labradorite types) and olivine phenocrysts.
• The same rocks often contain similar aggregates of plumose skeleton crystals of augite.
• Nakhlites are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 billion years ago.
• Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).

• Most of the dolerites are fine to medium grained, dark grey rocks with augite and plagioclase as major constituents.
• The close view of the rocks in the Adel mountains show large glossy crystals of augite in a dark grey matrix made up of small crystals of augite and feldspar.
• Jeffersonite is a dark green pyroxene mineral, a manganese zinc enriched variety of augite, chemical formula [...] , sometimes compared to aegirine. Jeffersonite is not a recognized mineral name.
• Fassaite is a variety of augite with a very low iron content, [...]. It is named after the Fassa Valley, Italy.
• Essexite can be considered as an alkali gabbro or monzodiorite primarily composed of nepheline, plagioclase, with lesser amounts of alkali feldspar, with mafic minerals composed of any of the following; titanium augite (pyroxene), hornblende and biotite.

• More specifically, it is a variety of porphyritic phonolite or trachyte with rhomb-shaped phenocrysts of anorthoclase with variable amounts of olivine and augite in a glassy matrix; the glass may be devitrified.
• Corroded phenocrysts of biotite and hornblende are very common in some lavas; they are surrounded by black rims of magnetite mixed with pale green augite.
• The mineral assembly in basanite is usually abundant feldspathoids (nepheline or leucite), plagioclase, and augite, together with olivine and lesser iron-titanium oxides such as ilmenite and magnetite-ulvospinel; minor alkali feldspar may be present.
