Exempel på hur man kan använda AUGITE i en mening

• They consist essentially of very small crystals of minerals such as plagioclase feldspar, with hornblende or augite, and may contain also biotite, quartz, and orthoclase.
• Diopside and hedenbergite are important endmembers in augite, but augite can also contain significant aluminium, titanium, and sodium and other elements.
• Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).
• Diopside is found in ultramafic (kimberlite and peridotite) igneous rocks, and diopside-rich augite is common in mafic rocks, such as olivine basalt and andesite.
• Pyroxenite is an ultramafic igneous rock consisting essentially of minerals of the pyroxene group, such as augite, diopside, hypersthene, bronzite or enstatite.
• If cooled more slowly they consolidated as crystalline rocks not unlike the whinstones themselves and containing olivine, augite and feldspar (the essential minerals of these rocks).
• The volcanic rocks contain augite and feldspar; further, spinel-containing lherzolite xenoliths have been found.
• Hedenbergite is a part of a pyroxene solid solution chain consisting of diopside and augite, and is the iron rich end member.
• It is a groundmass of plagioclase, with amphibole (hornblende), biotite, pyroxene (augite), quartz, and glass; it also includes phenocrysts of plagioclase.
• Theralite (from Greek "to pursue") is, in petrology, the name given to calcic foidal gabbro, a plutonic hylocrystalline rock consisting of augite, olivine, calcic plagioclase (labradorite), and nepheline, along with accessories including biotite, magnetite, ilmenite and analcime.
• Jeffersonite is a dark green pyroxene mineral, a manganese zinc enriched variety of augite, chemical formula , sometimes compared to aegirine.
• The black spots on some specimens are either augite or aegirine, the latter occurring in almost all charoites since they commonly grow together.
• The diabase is typically dark gray to black, dense, and fine grained, consisting of predominately labradorite and augite.
• In uralitization, secondary hornblende replaces augite; chloritization is the alteration of augite (biotite or hornblende) to chlorite, and is seen in many diabases, diorites and greenstones.
• 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.
• After passing Oakford, it passes through a small deposit of mafic gneiss, from the Precambrian, which contains calcic plagioclase, hypersthene or augite, quartz, and hornblende.
• Peperino is an Italian word describing a brown or grey volcanic tuff, containing fragments of basalt and limestone, with disseminated crystals of augite, mica, magnetite, leucite, and other similar minerals.
• These rocks in turn include amphibole, apatite, biotite, clinopyroxene, garnet, ilmenite, mica, olivine, orthopyroxene, plagioclase, pyroxene in the form of augite, bronzite, diopside, hypersthene and salite, and quartz.
• Pigeonite crystallizes in the monoclinic system, as does augite, and a miscibility gap exists between the two minerals.
• Other minerals include anhydrite, augite, plagioclase which is also the dominant phenocryst phase in Lascar rocks, apatite, ilmenite, magnetite, olivine, orthopyroxene, phyrrotite, quartz, rhyolite in the groundmass, and spinel in inclusions.
