    Sammanfattning : Combining petrological and geochronological data we were able to show that rocks in south Naxos completed a full blueschist-/greenschist-facies metamorphic loop in about 10 Myr, distinctly faster than hitherto believed. We show that the high-pressure rocks reached peak pressure (16.3±0.9 kbar - 619 ±32°C) between 40. LÄS MER

  2. 2. The metamorphic history of Naxos (central Cyclades, Greece) : Deciphering the Oligocene and Miocene exhumation events

    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Cycladic Blueschist Unit; exhumation; fluid flow; geothermobarometry; Hellenide orogen; Rb-Sr dating; subduction-zone metamorphism; Heat flow; Lower crust; extensional domain; Metamorphic core complex; Geology; geologi;

    Sammanfattning : High pressure, low temperature (HP-LT) rocks observed at the surface of the Earth are evidence ofpast subduction zones. Understanding the tectonics processes that control the exhumation of HP-LT metamorphic rocks in these subduction zones requires full comprehension of the pressure-temperature-time (P–T–t) cycle that the rocks experienced.
