Exempel på hur man kan använda DUNITE i en mening

• Hard stone – granite, granodiorite, diorite, feldspar, quartz (silica stone), sand (including silica sand), petuntse (pottery stone), dunite.
• Hellyerite forms in this environment in nickel rich serpentinites, which are metamorphosed equivalents of ultramafic cumulate rocks such as peridotite and dunite.
• Heazlewoodite is formed within terrestrial rocks by metamorphism of peridotite and dunite via a process of nucleation.
• Platinum occurs in this woreda, developed on serpentinized dunite, locally named Birbirite, after the Birbir River; the platinum probably being remobilized and concentrated by hydrothermal alteration in conjunction with shearing.
• In the lower four magmatic series, masses of chromite, olivine and clinopyroxene develop rocks varying from dunite to clinopyroxenite.
• Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx.
• Petrology of the Twin Sisters dunite consists of Enstatite rich rocks that contain, along with olivine, significant amounts of chromite, clinopyroxene, and serpentinite.
• The Ultramafic series is composed of a lower peridotite member (Peridotite zone) consisting of alternating dunite, chromitite, harzburgite and bronzite pyroxenite.
• Such models incorporate interconnected porosity to facilitate buoyant flow of liquids from lherzolitic or harzburgitic assemblages, such as replacive dunite formation in migration channels.
• Nearly the entire area is underlain by dunite, a variety of peridotite consisting of dark green olivine and minor chromite, which has been partly or entirely serpentinized to antigorite magnesite-magnetite.
• phosphorite, dolomite, gypsum, garnet, wollastonite, vermiculite, ochre, perlite, bentonite, asbestos, cadmium, felspar, soapstone, kaolin, sillimanite, limestone, diatomite, pyrophyllite, fluorite, vanadium, dunite, ilmenite, gallium and zircon.
• It is found in massive sulfide from pipe-shaped dunite pegmatite in the norite zone of the Bushveld igneous complex in South Africa.
• Two orebodies, the Upper Group 2 (UG2) and the Merensky Reef, host about 70% of the world's platinum group metals (PGM), and pose major extraction problems for the mining industry in their faults, dykes, joints, domes, iron-rich ultramafic pegmatoids, rolls and dunite pipes.
• The parent rock of this banded variety most likely was a pyroxenite enclosing cumulate layers of dunite.
• The mantle parts of the lithosphere are made of harzburgite and dunite (both peridotites), with about 50 to 80% of the minerals now transformed into serpentinite.
• At Zanago, the belt is slightly different, with amphibolite-bearing quartzite, residual pyroxenite in amphibolites and small amounts of dunite.
• Mantle rocks exposed in the ophiolite are the peridotite varieties of lherzolite, harzburgite and dunite.
• Nappe formations, such as the Kulkuduk Unit are composed of basal serptinized dunite and lherzolite, with overlying harzburgite and layered gabbro.
• This feature left behind a highly stratified obducted ophiolite island arc assemblage with tectonized peridotite, dunite, lherzolite, wehrlite and troctolite, as well as pillow lava meta-basalt, and sheeted dikes of micro-gabbro and dolerite.
• Lower units include harzburgite interpreted as deformed mantle, overlain by massive gabbro, with dunite bodies left from mantle diapirs.
