Comment:
Isotopic analyses of 87 samples were conducted at the Pacific Centre for Isotopic and Geochemical Research (PCIGR), University of British Columbia, following procedures outlined in Weis et al. (2006). Approximately 100-250 mg of sample powder was fully digested using heated 48 % HF and 14N HNO3 in high-pressure PTFE bombs. Digested samples were subsequently brought to dryness and reconstituted with 6N HCl prior to ion exchange, where Nd and Sr were quantitatively isolated. Isotopic measurements of Sr and Nd were conducted using a Thermo Finnigan Thermal Ionization Mass Spectrometer (TIMS). The Sr and Nd isotopic ratios were normalized to correct for mass fractionation using 86Sr/88Sr = 0.1194 and 146Nd/144Nd = 0.7219. 143Nd/144Nd ratios were converted to epsilon-Nd using a value of 0.512636 for CHUR (chondritic uniform reservoir).
