A version of electron probe microanalysis of volcanic glass at GEOMAR, Kiel (Germany)

This dataset describes a version of electron probe microanalysis (EPMA) of Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, P, F, S, and Cl in volcanic glasses spanning a wide compositional range, conducted using a JEOL JXA-8200 (23.19.2012 - 31.12.2025) and JEOL JXA-iSP100 (01.01.2026 - present) at the GEOMAR Helmholtz Centre for Ocean Research Kiel (Germany) .
