Sr and Nd isotopic data for the seven GSJ rock reference samples; JA-1, JB-1a, JB-2, JB-3, JG-1a, JGb-1 and JR-1

We measured 87Sr/86Sr and 143Nd/144Nd ratios and carried out analytical test of Sr and Nd isotopic standards for the seven GSJ rock reference samples (hereafter GSJ-RRSs); JA-1, JB-1a, JB-2, JB-3, JG-1a, JGb-1 and JR-1. Our mean values of five separate analyses for the GSJ-RRSs are summarized in Tab...

Summary:We measured 87Sr/86Sr and 143Nd/144Nd ratios and carried out analytical test of Sr and Nd isotopic standards for the seven GSJ rock reference samples (hereafter GSJ-RRSs); JA-1, JB-1a, JB-2, JB-3, JG-1a, JGb-1 and JR-1. Our mean values of five separate analyses for the GSJ-RRSs are summarized in Table 1, in agreement with the ranges of previously published data. Our mean values for 87Sr/86Sr ratios of JB-2 and JGb-1 and 143Nd/144Nd ratio of JR-1, however, show a slightly large variation as compared with the other JGS-RRSs. Further data accumulation with specification of split/position number is required to evaluate homogeneity in Sr and Nd isotopic compositions.
