ABSTRACT:  Kefdağ ve Soridağ chromilite bodies were occured in cth.e diapiric upper mantle residual peridotite«,. "These are consist of harzburgite and dunite which are residiuals of `the multi stage depleted upper mantle. Kefdağ and Soridağ chromitite bodies, were occured during `the rising of the picritic melts of the fertile I1e.rz0ll.tic origin, through the residual upper mantle diapir along the magma conduits.. ChTomite grains were deposited in the. caves of the magma, conduits under the control of the convection currents..
