Secondary standards for major element oxide analyses for the geochemical composition of analysed volcanic events from B19, TUNU2013, and RECAP Greenland ice cores and correlating proximal material from Iceland between 750 and 940 CE@en

Secondary Standards of Cannetto Lami Lava, Lipari and BCR-2Ga for major element oxide tephra glass analyses obtained across the period 750-940 CE. Data was obtained using electron probe micro-analysis (EPMA) at the University of Bern, Switzerland, Queen's University Belfast, UK, and University of Edinburgh, UK.公元750年至940年间获取的、用于火山碎屑玻璃主量元素氧化物分析的坎内托·拉米熔岩（Cannetto Lami Lava）、利帕里（Lipari）样品及BCR-2Ga二级标准物质数据集。本数据集的测试数据通过电子探针显微分析（electron probe micro-analysis, EPMA）方法采集，测试机构包括瑞士伯尔尼大学、英国贝尔法斯特女王大学与英国爱丁堡大学。
