Possible sub-arc origin of podiform chromitites

open access: yesPossible sub-arc origin of podiform chromitites
The sub-arc mantle condition possibly favors the formation of podiform chromitites. The Cr/(Cr + Al) atomic ratio (= Cr no.) of their chromian spinel frequently is higher than 0.7. This almost excludes the possibility of their sub-oceanic origin, because both oceanic peridotites and MORB have chromian spinel with the Cr no. < 0.6.
