资源简介：
Mean composition data based on <em>n</em> single DeepCHALLA cryptotephra glass shard analyses of major and minor element oxides (by WDS-EPMA, <em>n</em>=32) and trace elements (by LA-ICP-MS, <em>n</em>=19). Also shown are compositions of secondary glass standards measured during the same instrumental runs, and their correspondence with approximate expected values for in-house Lipari glass and with GeoRem-preferred (pref. val.) or true values for MPI-DING glass secondary standards (Marshall et al., 2009; Scot and Skilling, 1999).
