资源简介:
Sediment depth is given in mbsf. Epsilon-Nd is calculated for approximate time of eruption, where known (60 Ma for SE Greenland, Vøring Plateau, and Hatton Bank; present day for Iceland neovolcanic zone lavas). Sr and Pb isotope data are reported as present-day ratios, because we have no values for the Rb/Sr, U/Pb, and Th/Pb of the parental material (in this case, the leached residues).
