Comment:
T = 120 Ma for Site 807,90 Ma for Site 803. Isotopic fractionation corrections are 148NdO/144NdO = 0.242436 (148Nd/l44Nd = 0.291572), 86Sr/88Sr = 0.1194. Data are reported relative to University of Hawaii standard values: for La Jolla Nd, 143Nd/144Nd = 0.511855; for BCR-1, see above; for NBS 987 Sr, 87Sr/86Sr = 0.71025; for E and A Sr, 87Sr/86Sr = 0.70803. The total range measured for La Jolla Nd is ±0.000012 (0.2 epsilon units); for NBS 987 it is ±0.000022. Within-run errors on the isotopic data above are less than or equal to the external uncertainties on these standards. Total blanks are negligible: <20 picograms for Nd and <120 picograms for Sr. Uncertainties on Nd and Sm abundances are estimated at <0.2%; on Sr and Rb, <0.5% and - 1 % , respectively. epsilon-Nd(T) = 0 today corresponds to 143Nd/144Nd = 0.512640; epsilon-Nd(T) = 0 at 120 Ma corresponds to (143Nd/144Nd)T = 0.512486 for 147Srn/144Nd = 0.1967, and to 0.512524 at 90 Ma.
