Exempel på hur man kan använda PYROXENITE i en mening

• Founded in 1951, Foskor's Mining Division in Phalaborwa mines phosphate rock (foskorite and pyroxenite), from which Foskor's Acid Division in Richards Bay produces phosphoric acid and phosphate-based granular fertilisers for local and international markets.
• Websterite is ultramafic igneous rock, a type of pyroxenite that has less than 5% olivine and roughly equal proportions of orthopyroxene and clinopyroxene.
• Below the Ultramafic-Mafic sequences' contact, and in the uppermost pyroxenite (bronzitite and websterite) units are economic concentrations of nickel, copper, cobalt, gold, and platinum group metals (PGM).
• The bands and layers of ultramafics and mafic rocks (Ultramafic and mafic rocks represented by meta pyroxenite, talc-tremolite-actinolite schist, and amphibolites) of varying dimensions, banded iron formation(BIF), sillimanite/kyanite bearing quartzite and fuchsite quartzite occurring within the Peninsular Gneissic Complex of Attappadi area designated as Attappadi Supracrustals.
• The Ultramafic series is composed of a lower peridotite member (Peridotite zone) consisting of alternating dunite, chromitite, harzburgite and bronzite pyroxenite.
• The complex includes gabbro, pyroxenite, gabbronorite and websterite intrusive into granitic gneiss country rock.
• The parent rock of this banded variety most likely was a pyroxenite enclosing cumulate layers of dunite.
• Orthopyroxenite is an ultramafic and ultrabasic rock that is almost exclusively made from the mineral orthopyroxene, the orthorhombic version of pyroxene and a type of pyroxenite.
• Baltimore Gabbro Complex is a hypersthene gabbro with subordinate amounts of olivine gabbro, norite, anorthositic gabbro, and pyroxenite.
• Rock debris found on Macdonald seamount includes intrusive rocks such as gabbro, metadolerite, picrite and pyroxenite; the gabbros appear to originate from slow crystallization of basaltic magma within a magma reservoir, followed by low temperature alteration.
• Various xenoliths have been found, including garnet-containing clinopyroxenite, harzburgite, garnet hornblendite, amphibole-containing peridotite, olivine and spinel pyroxenite, and websterite.
• At Zanago, the belt is slightly different, with amphibolite-bearing quartzite, residual pyroxenite in amphibolites and small amounts of dunite.
• Together with gabbro, serpentinized pyroxenite and diabase and numerous radiolarian fossils, they form an ophiolite mélange from the Paleozoic, overlain by four kilometers of sandstone, clay, tuff and conglomerate.
• Xenoliths of amphibole, calcite, clinopyroxene, dunite, garnet, garnet peridotite, orthopyroxene, phlogopite, garnet pyroxenite, lherzolite and spinel have been described.
• The basement rocks of the region are represented by pre-Jurassic, small-scale metamorphic masses, generally composed of gneiss, schist and amphibolites, which includes dunite, harzburgite, lherzolite, wehrlite, pyroxenite and abbro giving outcrop over large areas.
• The vent contains volcanic clasts of mainly phonolite, with minor proportions of basanite, basaltic-trachyandesite, trachyandesite, syenite, gabbro, pyroxenite, and hornblendite, as well as fragments of Otago Schist and Cenozoic sedimentary rocks.
• On Government Peak, a 90 Ma (million years old) rock unit variously mapped as gneiss, or as intricately intermixed amphibolite and quartz diorite, or as a migmatite, and most recently as a mafic unit of gabbro and pyroxenite with local foliation and mylonitic textures structurally underlies the Arkose Ridge Formation and outcrops in between the Hatcher Pass schist and the arkose.
