Fig. 2 — Zircon age data are displayed as ranked order plot and kernel density estimate (blue lines) with bandwidth of 20 ka. U-Th ages are shown as filled circles and U-Pb ages as open squares. Eruption ages, if constrained, are marked by vertical red lines³⁶. a Upper Toluca Pumice (UTP). b Middle Toluca Pumice (MTP). c Block and Ash Flow 28 (BAF). d White Quarry Pyroclastic flow (WQ). Subpanel e shows the combined ranked order-age plot for all studied eruptions with color coding for the individual eruptions: UTP: red, MTP: purple, BAF: green, and WQ: white. The number of analyzed spots on zircon crystals (n) is indicated on each subpanel and 1 sigma error bars are shown. Combined U-Th and U-Pb zircon age spectra for the individual eruptions are overlapping with each other and indicate prolonged crystallization.
