Comment:

Nd isotope ratios are relative to the value recommended by Chauvel and Blichert-Toft (2001, doi:10.1016/S0012-821X(01)00379-X) for the Rennes Nd standard (143Nd/144Nd = 0.511961, which corresponds to a La Jolla value of 0.511856). Uncertainties reported on the Nd isotope ratios are in-run errors (2 sigma), where sigma is the standard deviation and n the number of measured 143Nd/144Nd ratios, generally 60). The Rennes Nd standard was run every second sample and its reproducibility (2sigma) calculated on each analyses session (~20 analyses) is typically 30 ppm. Reproducibility calculated using complete duplicate analyses of 7 samples is 1.2 * 10**-5 (2 sigma) on the measured 143Nd/144Nd ratio (25 ppm) and is better than the average in-run errors. Pb isotope ratios are relative to NBS 981 values of 206Pb/204Pb = 16.9405, 207Pb/204Pb = 15.4963 and 208Pb/204Pb = 36.7219 (Galer and Abouchami, 1998). The NBS 981 standard was run every second sample and its reproducibility (2 sigma) calculated on the entire period of analyses is 150, 180 and 200 ppm for 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb ratios respectively (106 analysis). Reproducibility calculated using complete duplicate analyses of 8 samples, excluding the 4 duplicates of black shales (Site 144 - Unit 3), is 0.007 (370 ppm), 0.002 (130 pm) and 0.011 (300 ppm) for 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb ratios respectively (2 sigma). The reproducibility of the black shale duplicates is not as good probably because of the strong heterogeneities of these samples.
