Exempel på hur man kan använda HYPERSTHENE i en mening

• The dominant phenocrysts are zoned plagioclase, hypersthene, calcic clinopyroxene, titanomagnetite, and rimmed olivine.
• In addition, black, chatoyant hypersthene and brownish bronzite are also used as semi-precious gemstones.
• Bronzite is a member of the pyroxene group of minerals, belonging with enstatite and hypersthene to the orthorhombic series of the group.
• Pyroxenite is an ultramafic igneous rock consisting essentially of minerals of the pyroxene group, such as augite, diopside, hypersthene, bronzite or enstatite.
• A special feature, recurring in many members of the group, is the presence of a strongly pleochroic, reddish or green orthopyroxene (ferroan enstatite formerly known as hypersthene).
• 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.
• 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.
• The most abundant minerals are olivine and hypersthene (an orthopyroxene), as well as iron–nickel and troilite.
• In nearshore marine deposit sediment, the source material is less quartz (less silica) compared to upriver sources; heavy minerals include pyroxene (a group of silicate minerals), hypersthene (magnesium iron silica), and diopside (magnesium calcium silica).
• There is a moderate quantity of phenocrysts, including biotite, hornblende, ilmenite, hypersthene, magnetite and plagioclase, with little apatite and orthopyroxene.
• Holland reclassified the hypersthene granites as acidic (the charnockites, with the type being from St Thomas Mount), the intermediate, basic, and ultrabasic.
• In geology, enderbite is an igneous rock of the charnockite series, consisting essentially of quartz, antiperthite (or perthite), orthopyroxene (usually hypersthene) and magnetite, and is equivalent to an orthopyroxene bearing tonalite.
• Most of these have a porphyritic texture, containing phenocrysts; basaltic andesite deposit phenocrysts are made of minerals like light to dark-gray hypersthene, clinopyroxene, or olivine, and the andesitic deposits have minerals such as platy pyroxene or olivine.
• Varying amounts of phenocrysts occur in the Purico complex rocks; the minerals they are formed of include augite, biotite, clinopyroxene, hornblende, hypersthene, iron oxides, oligoclase, orthopyroxene, plagioclase, quartz and titanium oxides.
• The groundmass of alkali basalt is mainly composed of olivine, titanium-rich augite and plagioclase feldspar and may have alkali feldspar or feldspathoid interstitially, but is poor in silica minerals, such as hypersthene and quartz.
• Baltimore Gabbro Complex is a hypersthene gabbro with subordinate amounts of olivine gabbro, norite, anorthositic gabbro, and pyroxenite.
• These Saouda Series rocks include gneiss, with different endmembers enriched in leptynite garnet, hypersthene and sillimanite garnet, as well as pyroxene amphibolite, magnetite quartzites and marble.
• Apatite, basaltic sandstone containing hypersthene, clay, limestone, manganese crusts, manganese oxide, phosphorite and lithified carbonates have been found on Cape Johnson Guyot; some carbonates of biogenic origin have been altered by apatite.
• Phenocrysts include biotite and plagioclase, while apatite and zircon form accessory phases; orthopyroxene, quartz and sanidine are less common and clinopyroxene, hercynite, hornblende, hypersthene, ilmenite and magnetite are rare.
