Chemical composition as well as different iomc ratios of chrome spinels of Beula-Nausahi ultramafic body, Orissa, have been determined. These data tell about the nature of original magma and temperature and oxygen fugacity of chromite crystallization. These data when compared with other well-known chromite deposits of the world, reveal a stratiform mode of origin for the deposit.
