Research Abstract |
Malakand ophiolitic peridotite, which is fragment formed by convergence of Indian and Eurasia plates, represents the uppermost mantle beneath an island arc. The main constituents are strongly depleted harzburgite with intercalating dunite, which includes minor chromitite. Based on the field occurrence, petrologic and mineralogic studies and rare earth elements compositions of the ultramafic rocks, an interaction between residual mantle wall rock and the percolating melt around the uppermost mantle is important to consider the magma process.
