| 英文摘要 | Barium (Ba) isotopes have been developed as a valuable tracer for chemical weathering, marine biogeochemical processes, and riverine Ba input to the ocean. To facilitate inter-laboratory data comparisons, it is essential to measure Ba isotope ratios of widely available reference materials. We presented 21 geological reference materials, most of which are new stream sediment Ba isotope reference materials in this study. Purification of synthetic solutions and rock samples with different Ba concentrations and matrix compositions, showed similar elution curves with recoveries close to 100 %. The long-term reproducibility for delta Ba-138/134 measurements was <= 0.07 parts per thousand (2SD). The results indicated that the Ba isotope ratios of AGV-2, BCR-2, BHVO-2, GSP-2, RGM-2, GSS-2, GSR-1, GSR-2 and GSR-5 were in good agreement within analytical uncertainties with previously published data. The delta Ba-138/134 values of sediment materials ranged from -0.31 +/- 0.06 parts per thousand to 0.03 +/- 0.07 parts per thousand.With the exception of one stream sediment from a carbonate tributary, all analyzed sediment reference materials exhibited significant homogeneity in Ba isotopic composition, with an average delta Ba-138/134 of 0.01 +/- 0.06 parts per thousand, which was in excellent agreement with the upper continental crust (0.00 +/- 0.05 parts per thousand) and the bulk silicate earth (0.07 +/- 0.08 parts per thousand). This dataset of reference materials in this study provides the basis for data quality assurance and later inter-laboratory comparison of Ba isotope analyses. |
