Some primary structures in the chromitites of Orissa, India

1972-9-1  Some important primary structures have been studied and described from the chromities of Sukinda Valley in Orissa, India. The structures include primary layering, ‘Ball and Pillow’ structures, and cross laminations. From the similarity of the structures and texture of the chromitites with the sedimentary rocks, it is presumed that the chromities were formed by magmatic sedimentation under ...

Abstract This chapter reviews the Archean greenstone belt-hosted chromite deposits of India. These deposits are significant in tracing the crustal and mantle evolution of the Earth. This is because chromites are important petrogenetic tools that retain the composition of the parental melt from which they crystallize in a particular tectonic setting.

Chromite: The only mineral ore of chromium metal

What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.
