Abstract:

This dataset contains Sr, Nd, Pb, and Hf isotope geochemistry from the Agulhas Plateau, Maud Rise, Northeast Georgia Rise, and Mozambique Ridge, along with the associated trace element data needed for age corrections. The samples used come from IODP Exp. 392 (Agulhas Plateau), ODP Leg 113 (Maud Rise), ODP Leg 114 (Northeast Georgia Rise), DSDP Leg 25 (Mozambique Ridge), as well as two continental samples from the Falkland Plateau from DSDP Leg 36. Two sediment samples were also analyzed from the Agulhas Plateau.
