New and recalculated U-Th zircon ages from large-silicic eruptions of Atitlán caldera based on new bulk-rock U-series data (Table S3)

This dataset presents zircon 238U-230Th disequilibrium dates from multiple tephra samples from the Atitlán caldera in Guatemala, Central America. Zircon 238U-230Th isotope compositions were obtained using secondary ion mass spectrometry (SIMS) at Heidelberg University, Germany. Dates were calculated using the isochron method and new bulk-rock U-series data presented in Table S2.
