(Table 3) Radiogenic isotope ratios of ODP Hole 126-793B

Oligocene fore-arc. Sample powders (all 0-5% plagioclase phyric) were leached for 6 h in 6 M HCl before Sr isolation. Rb/Sr ratios were determined on the post-leach residue by ICP-MS following a HF-HNO3 dissolution Nd analyses were also performed on powders leached in 3 M HCl for 2 h to eliminate the possibility of extraneous Nd introduced by the pervasive REE mobility in these lava suites (Taylor et al., 1992, doi:10.2973/odp.proc.sr.126.146.1992, Taylor et al., 1995). Pb isotopes for these ODP Holes were analysed at Royal Holloway, University of London. Pb isotopes are from Taylor et al. (1992, dataset: doi:10.1594/PANGAEA.713800) re-corrected for mass fractionation to SRM 981
