Here we report boron (B) mass fractions and δ¹¹B values of a set of geological reference materials including ultramafic rocks, basalts, andesites, felsic rocks and sedimentary materials. Boron was purified using a single column loaded with AGMP-1 resin. The δ¹¹B data were determined by multi-collector inductively coupled plasma-mass spectrometry (MC-ICP-MS) using the sample-standard bracketing method, and the NIST SRM 951 reference solution was selected as the calibrator. Boron mass fractions were measured by ICP-MS. Based on analyses of the NIST SRM 951 reference solution over a period of 1 year, the intermediate measurement precision for B isotope determinations was better than 0.5‰ (2s). The robustness of the overall B isotope analytical procedure was evaluated by carrying out replicate analyses of five reference materials (i.e., B5, JB-2, JB-3, B6 and JR-2). The eighteen geological reference materials have δ¹¹B values ranging from −28.85 to +10.47‰ and B mass fractions ranging from 2.37 to 158 μg g⁻¹. The comprehensive data set presented here serves as a reference for quality assurance and comparison of B isotope and B mass fraction data among different laboratories.

十八种国际地质标准物质的硼质量分数和 δ11B 值

在这里，我们报告了一组地质参考材料的硼 (B) 质量分数和δ ¹¹ B 值，包括超基性岩、玄武岩、安山岩、长英质岩和沉积材料。使用装载 AGMP-1 树脂的单柱纯化硼。的δ ¹¹ B数据通过使用采样标准包围方法多电感耦合等离子体-质谱（MC-ICP-MS）确定，并且NIST SRM 951参考溶液被选定为校准器。硼的质量分数通过 ICP-MS 测量。根据对 NIST SRM 951 参考溶液 1 年时间的分析，B 同位素测定的中间测量精度优于 0.5‰ (2 s）。通过对五种参考材料（即 B5、JB-2、JB-3、B6 和 JR-2）进行重复分析，评估了整个 B 同位素分析程序的稳健性。十八种地质参考物质的δ ¹¹ B 值范围为-28.85 至+10.47‰，B 质量分数范围为2.37 至158 μg g ^-1。此处提供的综合数据集可作为质量保证和不同实验室间 B 同位素和 B 质量分数数据比较的参考。
