Nd, Pb and Sr Isotopic Compositions of East African Carbonatites: Evidence for Mantle Mixing and Plume Inhomogeneity

New Pb isotopic data are presented for 10 young Mesozoic to their variation in age can provide valuable insights into Cenozoic (0-116 Ma) carbonatites from a 1400 km long segment the nature of the sub-continental mantle over a period of the East African Rift. Patterns observed in Pb vs Pb, Sr vs Pb ... View More
