Comment:
The samples were analysed on a Thermo Scientific TRITON TIMS using total spiking with a 150Nd spike Neodymium was loaded mixed with Aquadag graphite on double rhenium filaments and run as metal in static mode using rotating gain compensation. Concentrations and ratios were reduced assuming exponential fractionation. Calculated ratios were normalised to 146Nd/144Nd = 0.7219. The external precision for 143Nd/144Nd as judged from values for nNd-beta standard was 43 ppm. Accuracy correction was not necessary since the mean 143Nd/144Nd ratio was 0.511895±22 (n=20).
