Glass chemistry of eruption deposits from volcanoes around Mexico City (NERC Grant NE/S009035/1)
Electron microprobe glass chemistry data from explosive eruption deposits from Popocatépetl, Iztaccíhuatl and Tláloc-Telapón volcanoes in Central México, spanning the last 700 ka. Associated with the following paper: Sunyé-Puchol, I., Hodgetts, A.G.E., Watt, S.F.L., Arce, J.L., Barfod, D.N., Mark, D.F., Sosa-Ceballos, G., Siebe, C., Dymock, R.C., Blaauw, M., Smith, V.C., 2021.

Data Quality
These major element concentrations in the glass shards were analysed using a JEOL JXA-8200 electron microprobe equipped with five wavelength-dispersive spectrometers in the School of Archaeology, University of Oxford, UK. A beam accelerating voltage of 15 kV was used with a 6 nA current and a beam diameter of 10 μm. A narrower beam of 5 μm was used for a few highly vesicular samples (noted by a * in the file). The EMP was calibrated using a suite of mineral standards. This calibration was verified using a range of secondary glass standards (ATHO-G, StHs6/80-G and GOR128-G; Jochum et al., 2006).
