Time-resolved oxygen isotopes and trace element compositions from the TB eruption suite zircon crystals (Table S4)

This dataset includes results from trace element concentrations from zircon rims (outermost crystal face) and crystal interiors (polished sections) of the last four explosive silicic eruptions from Ilopango caldera (TBJ, TB2, TB3, and TB4) in El Salvador. Zircon crystals were analyzed employing Secondary Ion Mass Spectrometry at Heidelberg University.
