...Olivier Bachmann; Sharon R. Allen; Caroline Bouvet de Maisonneuve The KosNisyros–Yali volcanic field has produced a range of volcanic products over the last 3 million years. Volumetrically, silicic magma dominates, and activity includes one of the largest known explosive eruptions of the Aegean...

.... In particular, like our case of the San Antonio ignimbrite, Bachmann et al. (2010) found that biotite 40 Ar/ 39 Ar ages of the units in the Kos-Nisyros volcanic complex are older than the youngest zircon U-Pb ages; they argued that in this context the youngest zircon U-Pb ages are a better approximation...

... of Nisyros is the most recent of the three volcanic centres discussed here, as the edifice was only established after the massive eruption that deposited the rhyolitic Kos Plateau Tuff at 161 ka ( Smith et al. 1996 ). The latest activity, producing felsic plugs within the caldera, may have been synchronous...
