Thermochronology of the high-pressure metamorphic rocks of Crete, Greece; implications for the speed of tectonic processes

New fission-track thermochronologic data from the high-pressure (P)-low-temperature (T) rocks of Crete, Greece, combined with pressure, temperature, and stratigraphic constraints reveal that their subduction began between 36 and 29 Ma. Metamorphism took place in western Crete at peak conditions of 1...

Description
Summary:New fission-track thermochronologic data from the high-pressure (P)-low-temperature (T) rocks of Crete, Greece, combined with pressure, temperature, and stratigraphic constraints reveal that their subduction began between 36 and 29 Ma. Metamorphism took place in western Crete at peak conditions of 10±2 kbar and 400±50°C between 24 and 19 Ma, and rapid exhumation to
