Interrelations between extensional shear zones and synkinematic intrusions: The example of Ikaria Island (NE Cyclades, Greece)

Abstract : The Aegean extensional backarc domain is an ideal place to investigate the interrelations between syntectonic intrusions and large-scale detachments, understanding whether the intrusions have a triggering effect on the inception of metamorphic core complex formation or not. A new field study of Ikaria Island (NE Cyclades, Greece) in two Miocene granitoid plutons intruding a high-temperature metamorphic dome, namely the Raches and Karkinagrion granites, leads to the identification of a major structure that has been omitted in previous studies: the Gialiskari Detachment. This regional-scale detachment is correlated with the North Cycladic Detachment System. Structural fieldwork at the scale of the entire Raches and Karkinagrion intrusions allows us to propose a map of strain intensity in these granites.
