1. Plagioclase, hornblende and augite are mostly in form as phenocrysts and comprise 1 % to 10 % of the andesite.
2. Nakhlites are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 billion years ago.
3. In rhyolites and trachytes, early crystals of hornblende and biotite may be found in great numbers partially converted into augite and magnetite.
4. Sometimes granular augite or spongy riebeckite occurs in the groundmass, but as a rule this part of the rock is highly feldspathic.
5. Minerals such as augite, magnetite, nepheline, olivine and perovskite have been identified in samples from the basaltic fan of Hirtstein.
