White mica bundles from the mylonitic foliation in the CBU yield 40Ar/39Ar dates of 25–19 Ma and zircon (U–Th)/He dates are 11–8 Ma. A weakly foliated granitic intrusion that cross-cuts the CBU is 8.5 Ma based on zircon U–Pb geochronology. Detrital white mica from the metaflysch yields Jurassic to early Palaeogene single grain 40Ar/39Ar dates, with a dominant Palaeocene signature. Zircon (U–Th)/He dating similarly reveals dispersed ages between 36 and 15 Ma suggesting Miocene metamorphic temperatures were insufficient (<200°C) to completely reset all of the zircon cooling ages. The low-grade rocks of the hangingwall above the newly discovered Miocene low-angle Santorini Detachment System most likely belong to the Pelagonian zone with a Triassic carbonate platform discordantly transgressed by an Eocene flysch deposit. © 2018 John Wiley & Sons Ltd" }
