- •
Ikaria Island corresponds to a large-scale migmatite-cored MCC.
- •
Thermal structure revealed by RSCM shows a drastic increase from top to bottom.
- •
The MCC was exhumed by two detachments through the brittle–ductile transition.
- •
Migmatites were dated to 15.7 ± 2 Ma by U–Th–Pb analysis on monazites.
- •
A large-scale high temperature zone is proposed for the central part of the Aegean.
