The Rare Earth Content and Origin of Alkali

The rare earth content of alkali-rich, silica-undersaturated basalts erupted onto oceanic and continental plates is consistent with their derivation by slight amounts of partial melting of hydrous garnet peridotite at the top of the asthenosphere, within the low-velocity, low-Q zone of the mantle The rare earths are fractionated during partial melting by retention of heavy rare ,...
