CRYPTIC VARIATION OF CHROMITE CHEMISTRY, PLATINUM …

The mineral chemistry of chromite is characterized by distinct cryptic variation, leading to the division of the UG-2 sequence into 10 distinct sublayers. From bottom to top (with exception of the basal sublayer), each sublayer is defined by an upward decrease of Mg# combined with increases of Cr# and TiO 2 .

Chromite

Chromite is a heavy, black mineral that has about the same specific gravity as barite. Its hardness is close to that of steel, but it can usually he scratched with a knife blade. The brown streak (powder of the mineral) ordinarily distinguishes chromite from other similar-appearing heavy black minerals, for most of these have black streaks.

CHROMITE (Iron Chromium Oxide) - Amethyst Galleries

Chromite forms in deep ultra-mafic magmas and is one of the first minerals to crystallize. It is because of this fact that chromite is found in some concentrated ore bodies. While the magma is slowly cooling inside the Earth's crust, chromite crsytals are forming and because of their density, fall to the bottom and are concentrated there.
