Chromitite is an igneous cumulate rock composed mostly of the mineral chromite. It is found in layered intrusions such as the Bushveld Igneous Complex in South Africa, the Stillwater igneous complex in Montana and the Ring of Fire discovery in Ontario. Chromitite typically forms as orthocumulate layered lenses in peridotite rocks, at times intergrown with other oxides such as magnetite and ilmenite, and silicates such as olivine, pyroxene, plagioclase feldspar (mainly anorthite), and garnet crystals. The chromium rich garnet uvarovite forms in interbedded layers with chromitite.

| - La cromitita és una roca ígnia cumulativa, formada principalment per cromita. Es troba en intrusions ígnies estratificades com ara el complex igni de Bushveld a Sud-àfrica, al complex igni de a Montana, Estats Units, i a l' a Ontàrio, Canadà. Les cromitites són la principal font de cromita i conseqüentment principal font de crom. La cromita forma acumulacions estratificades en roques peridotítiques, sovint intercreixent amb altres capes d'òxids com ara magnetita i/o ilmenita, i també silicats com ara olivina, piroxè, plagiòclasi, anortita i granat (sovint uvarovita, un granat ric en crom).
