Hf and Nd isotopic data of sediments from IODP LEG 113, Site 689D, Maud Rise, Antarctica ...
Sediment samples from IODP LEG 113 Site 689 Hole D (Maud Rise) sample the Eocene-Oligocene boundary (33.2 – 34.87 Ma). The objective is to elucidate the exact timing of the first glacial growth during the Eocene-Oligocene Transition (EOT; 34 Ma). The growth of the ice sheet could be inferred through...
