Chromite - Wikipedia
Chromite minerals are mainly found in mafic-ultramafic igneous intrusions and are also sometimes found in metamorphic rocks. The chromite minerals occur in layered formations that can be hundreds of kilometres long and a few meters thick. Chromite is also common in iron meteorites and form in association with silicates and troilite minerals. The chemical composition of chromite can be represented as FeCr2O4, with the iron in the +2 oxidation state
