Oceanic lithospheric mantle is generally interpreted as depleted mantle residue after mid-ocean ridge basalt extraction. Several models have suggested that metasomatic processes can refertilize ...
Studies of mid-ocean ridge basalts (MORBs) show a variable Fe isotope composition of the oceanic upper mantle, beyond explanation by processes of mantle melting from a uniform source and magma ...
Metasomatic processes in mantle xenoliths encompass interaction between percolating melts or fluids and the solid peridotitic or pyroxenitic mantle framework. Such interactions modify mineral ...
