The basalts are best understood as partial melting of metasomatized asthenosphere. (3) The alkali basalts show higher LILEs (e.g., Rb, Ba) and lower Ti than OIB. These signatures plus the high Ce/Pb and Nb/Y, and low Ba/Y and Ba/Th, favor the asthenospheric mantle source being enriched by metasomatism of slab-derived melt.
