The Darvazeh-Chenar mafic- ultramafic body is part of ophiolitic complex of Neyriz in Fars Province that formed in association with closing of Neo-Tethys Ocean and Arabian- Iranian plate collision in Cretaceous. The Faryab ophiolitic rocks are also remnant of block of Tethys oceanic crust that were obducted on continental margins in late Cretaceous period. MgO, Fe₂O₃, Al₂O₃, Cr₂O₃ and TiO₂ contents in Darvazeh-Chenar correspond to podiform chromites, which formed by a magma with bonititic composition containing high Cr# and low content of TiO₂, in a subduction zone. Faryab chromites have relatively high contents of Al₂O₃ and TiO₂ and have Cr# between 45.8 to 55.7, and originaged from a magma with the composition similar to that of the mid-oceanic ridge.
