| The plagioclase crystals would have formed subcircular lenses of anorthosite that punctuated background chromite accumulation. |
|
| Early minerals, such as the chromium-bearing mineral chromite, crystallize early and are denser than the surrounding magma. |
|
| Unbrecciated diogenite that shows orthopyroxenes and chromite grains that are partially fragmented and deformed. |
|
| Three oxide ore minerals form magmatic cumulates: chromite, magnetite, and ilmenite. |
|
| As a result, geologists long held the opinion that cumulates of chromite and other dense minerals formed only by sinking. |
|
| Accessory minerals may include sanidine, melilite, sodalite, perovskite, apatite, and chromite. |
|
| However, overall chromite refractory consumption in the steel industry is expected to stabilize in the next few years. |
|
| The relative abundance of pyrope, Cr-diopside, Mg-ilmenite and chromite varies between the four kimberlite pipes. |
|
| Most chromium chemicals are produced from sodium dichromate, which is manufactured directly from chemical-grade chromite. |
|
| The Big Trout Lake chromite mineralization in northern Ontario is hosted in a layered intrusion. |
|
| Other identified minerals in Sierra Leone include gold, iron ore, platinum, chromite, lignite, clay, copper, nickel, molybdenum, lead and zinc. |
|
| Current nomenclature is based upon chromite composition in addition to end use. |
|
| Uvarovite, a sparkling green garnet that often occurs on blocks of chromite, was named in honor of Earl Uvarov, a Russian politician of the nineteenth century. |
|
| Wholerock and chromite geochemistry suggests that these rocks have greatest affinity with picrites found on King Island, which have a latest Neoproterozoic age. |
|
| The chromium-bearing zone, estimated to be about 60 m thick, consists of chromite crystals concentrated in very thin bands within layers of mafic and ultramafic rocks in igneous intrusions. |
|
| In general, refractory requirements in the steel industry have changed to a higher magnesite-content brick, thereby decreasing the consumption of chromite in this application. |
|
| This simple picture was challenged in 1961 by E. Dale Jackson, a geologist employed by the U. S. Geological Survey, who studied chromite cumulates of the Stillwater Complex in Montana. |
|
| Refractories containing both chromite and magnesite are used in furnaces wherever basic slags and dust are encountered, such as in the ferrous and nonferrous metal industries. |
|
| Pyrope garnet, clinopyroxenes and chromite minerals are among the most typical diamond indicator minerals found in kimberlites. |
|
| The Philippines is rich in mineral resources, including gold, copper, nickel, and chromite which is used in the manufacture of steel and certain chemicals. |
|
|
|
| Valuable mineral components often occurring with black sands are monazite, rutile, zircon, chromite, wolframite, and cassiterite. |
|
| Amongst the ore mineral resources we should note large quantities of chromite in the Main Saranovsk deposit which is the only chromite deposit exploited in Russia currently. |
|
| Two samples contain highly anomalous concentrations of pyrope garnet and ilmenite with minor chromite and eclogitic garnet. |
|
| Mineral resources include mercury, silica, and chromite. |
|
| It turned out to be a meeting to settle a dispute over a chromite mine. |
|
| Iron ore is rare, but in some countries there is a considerable amount of copper, zinc, tin, chromite, manganese, magnesite and bauxite. |
|
| Other minerals that have been worked intermittently include gold, silver, chromite, diatomite, and dolomite, but none has been successfully exploited. |
|
| Bricks of 100 percent chromium ore have been largely replaced by bricks composed of mixtures of chromite and added magnesia for greater refractoriness, volume stability, and resistance to spalling. |
|
| The Ring of Fire, about twice as large as Prince Edward Island, is said to hold one of the world's largest and richest deposits of chromite, the key ingredient in making stainless steel. |
|
| The country has abundant reserves of bauxite, coal, dolomite, iron ore, manganese, limestone, magnesite and adequate reserves of chromite, graphite, lignite, and rock salt. |
|
| These processes became necessary when the Company was considering starting up production of the platiniferous chromite deposit on its Menarik-James Bay property. |
