Chromite | Chromium Ore, Properties, Uses and Occurrence …
Almost pure chromite is found in similar layers in sedimentary rocks. The layers are preserved when the sedimentary rocks metamorphose to form serpentinite. Referred to as chromitites, these rocks are the most important ores of chromium. The weathering of chromite ore bodies can also lead to its concentration in placer deposits.

Basics of Geochemistry and Mineralogy of Chromium
Chromite (Fe,Mg)(Cr,Al) 2 O 4 containing up to ~55 wt% Cr 2 O 3 is the major ore mineral of chromium and is an accessory mineral in many ultramafic rocks. Chromitite forms Cr-rich ore bodies, in which the content of chromite exceeds 30 vol.%; this results in local increase in the chromium concentration in the Earth's mantle.
