Major-element data of single glass shards (raw data, normalized, and from U1524 tephra found in the U1524 from IODP Expedition 374 sites. Analyses were carried out with a JEOL JXA 8230 electron probe microanalyzer (EPMA) at Victoria University of Wellington using wavelength dispersive spectrometry techniques. Data includes calibrated international standards including ATHO-G, T1-G (Jochum et al., 2006), and VG-568 (USNM 72854) analyzed to monitor instrumental drift as well as the precision and accuracy of the analyses.
