Eocene tectonometamorphism on Serifos (western Cyclades) deduced from zircon depth-profiling geochronology and mica thermochronology

► Serifos island of W. Cyclades preserves evidence of high-pressure metamorphism. ► SIMS U -Pb depth-profiling successfully resolved ages on ultra thin zircon rims. ► Zircon exhibits variably states of recrystallization. ► Mica Ar -Ar thermochonology indicate exhumation shortly following HP conditions. ► Coupled geochronology on deformed rock sequences yields Eocene ages.
