Raw major element oxide data obtained by EPMA for volcanic events analysed from B19, TUNU2013, and RECAP ice cores (Greenland) between 750 and 940 CE@en

Raw major element oxide data for volcanic events analysed from B19 [78.00°N/36.40°W], TUNU2013 [78.04°N/33.88°W], and RECAP [71.3°N/26.7°W] ice cores (Greenland) 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. Sample ID, sample depth (m), raw oxide values, and correlating horizon are provided.本数据集涵盖公元750年至940年期间，对格陵兰岛B19[北纬78.00°/西经36.40°]、TUNU2013[北纬78.04°/西经33.88°]及RECAP[北纬71.3°/西经26.7°]三处冰芯中的火山事件开展分析得到的主量元素氧化物原始数据。数据通过电子探针显微分析（electron probe micro-analysis, EPMA）技术获取，分析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。数据集包含样品编号、样品深度（单位：米）、原始氧化物含量值以及对应的地层位信息。
