(Table 4) Isotopic composition of Sr and Pb in clinopyroxene and plagioclase separates from rocks of ODP Hole 176-735B

Pb isotope analyses were corrected for mass fractionation using measured values of NBS981 and amounted to 0.12+/-0.02 (1 S.D.) %/AMU. The strontium isotope analyses were corrected for Rb interference, the ratios normalised to 86Sr/88Sr=0.1194 and corrected for fractionation by the exponential law and the results monitored by the international standard NBS987: 87Sr/86Sr=0.710257+/-0.000008 (1 S.D.), N=16.
