Marine Carbonates in the Mantle Source of Oceanic Basalts: Pb Isotopic Constraints

Abstract For almost fifty years, geochemists have been interpreting the clues from Pb isotopic ratios concerning mantle composition and evolution separately. The Pb isotopes of ocean island basalts (OIB) indicate that their mantle source is heterogeneous, most likely due to the presence of end-compo...
