OCEANIC basalts are produced by melting of the Earth's mantle and are widely used to probe its composition. The observation of systematic, coupled variations in the neodymium, strontium and lead isotopic compositions of these basalts1 has been widely interpreted as reflecting the mixing of identifiable mantle components. White2 and Zindler and Hart3 have suggested that the isotopic compositions of mid-ocean-ridge and ocean island basalts (MORB and OIB) can be considered as mixtures of a… CONTINUE READING
