This paper provides a review of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Advanced Land Imager (ALI), and Hyperion data and applications of the data as a tool for ore minerals exploration, lithological and structural mapping. Spectral information extraction from ASTER, ALI, and Hyperion data has great ability to assist geologists in all disciplines to map the d...

The Urals is one of the reference mobile belts mafic type characterized by a wide development ophiolites which are associated with numerous deposits chromites significant industrial importance. In this regard, estimation age rocks ophiolite association will be useful for analyzing regularities formation chromite deposits. This work presented results dating chromite-bearing Kluchevskoy mafic–ult...

Iron chrome oxide (FeCr 2O4), is a commercially viable and major ingredient of stainless steel. The Odisha state in India possesses 98% the pre-Cambrian India’s Chromite ore deposits Sukinda valley, Jajpur District. To meet present escalating demand for chromium steel industries, it urged to extract more satiate domestic needs. depletion deposits, rise demand, fewer mines, less conversion from ...

This paper describes an innovative process for the production of ferrochromium alloy via segregation reduction of chromite at 1300 ◦C in the presence of calcium chloride. Both charcoal and petroleum coke were used as the reductant. Individual polycrystalline ferrochrome carbide particles were produced, with their particle size and shape resembling that of the starting carbon particles. Interact...

In the present investigation, the oxidizing roasting process of chromite with sodium carbonate to prepare potassium dichromate crystals was studied in the microwave field with air, by heating the chromite and sodium carbonate. The chromite and sodium carbonate heated separately at 1000 ◦C in the microwave oven (frequency: 2.45 GHz; power 1.5 kW) in order to study the microwave absorption proper...

Investigations of the Mantle Transition Zone (MTZ; 410-660 km deep) by deformation experiments and geophysical methods suggest that the MTZ has distinct rheological properties, but their exact cause is still unclear due to the lack of natural samples. Here we present the first direct evidence for crystal-plastic deformation by dislocation creep in the MTZ using a chromitite from the Luobusa per...

The studied serpentinites occur as isolated masses, imbricate slices of variable thicknesses and as small blocks or lenses incorporated in the sedimentary matrix of the mélange. They are thrusted over the associated island arc calc-alkaline metavolcanics and replaced by talccarbonates along shear zones. Lack of thermal effect of the serpentinites upon the enveloping country rocks, as well as th...
