Podiform chromitites in the mantle sections of ophiolites belong to either high-Cr (metallurgical) or high-Al (refractory) varieties. Their highly variable compositions are reflected by different Cr#s [100Cr / (Cr + Al)] and Cr 2 O 3 and Al 2 O 3 contents of the chromite, falling in the boninitic and MORB fields, respectively. Parental magmas of …
