Glass major and trace element geochemistry from Atitlán caldera tephras (Table S1)

This dataset presents major and trace element concentrations of glass shards from tephra deposits of the Atitlán caldera in Guatemala, Central America. Major element compositions were analyzed using an electron microprobe at GEOMAR - Helmholtz Centre for Ocean Research Kiel, Germany, while trace element concentrations were determined through laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) at the Institute of Earth Sciences, Academia Sinica, in Taipei.
