इल्मेनिट इसके अंग्रेजी अर्थ का उदाहरण

The unusual blue coloration of the quartz is thought to be due to ilmenite inclusions.

It also occurs in the Earth's crust, in association with clinopyroxene, plagioclase, ilmenite, cristobalite, tridymite, fayalite, fluorapatite and potassic feldspar, and forms series with pyroxmangite.

Typical minerals are amphibole, biotite, pyroxene, ilmenite or other iron oxides and some plagioclase feldspar.

For instance, ulvospinel in igneous rocks such as basalt and gabbro commonly oxidizes during subsolidus cooling to produce regular intergrowths of magnetite and ilmenite.

Orebodies of platinum group elements, chromite, magnetite, and ilmenite are often associated with these rare intrusions.

When the iron content of the melt is sufficiently high, magnetite or ilmenite crystallise and, due to their high density, form cumulate rocks.

When oxide minerals exceed 90% of the bulk of the interval the rock may be classified according to the oxide mineral, for example magnetitite, ilmenitite or chromitite.

Strictly speaking, these would be magnetite orthocumulate, ilmenite orthocumulate and chromite orthocumulates.

The Shepherd's Discordant Zone is host to a laterally extensive vanadiferous magnetite and ilmenite adcumulate and mesocumulate deposit, forming a resource in excess of 120 Mt grading 5% V2O5.

In addition a few oxide-rich layers in the upper zone of the intrusion are ilmenite rich, although these appear not to be economic.
