Comment:
Neodymium isotopes were analysed using the Nu Plasma HR multi-collector mass spectrometer (MC-ICPMS) at the University of Cambridge, using bracketing of JNdi-1 for standard correction. 146Nd/144Nd was normalised to 0.7219. Reported 143Nd/144Nd are for 30 ratios and the error reported is the internal error of the analysis (2 sigma). The epsilon-Nd is reported with respective external errors (2 sigma) for that particular session, unless the internal error was larger than the external, in which case the combined internal and external error (2 sigma) is reported.
