process of changing chromite ore to chromite

Origin of the UG2 chromitite layer Bushveld Complex

INTRODUCTION Stratiform chromitites are common features of large layered intrusions Most mechanisms proposed to account for the chromitites involve changes in chemical or physical conditions that cause the magma to become supersaturated in chromite and remove other phases from the liquidus thus inducing chromite to crystallize and accumulate in monomineralic layers on the magma...
