Detailed mapping and new structural observations on Kythera demonstrate that there is a major detachment fault, here termed the Potamos detachment fault (PDF), exposed on the northern part of the island and bordering the domed structure of a metamorphic core complex. The detachment forms the contact of contrasting metamorphic and nonmetamorphic units, and both ductile and brittle structures are found, related to its extensional development. The earliest Potamos mylonites, as well as some other… 
Extensional tectonics in Mt Parnon (Peloponnesus, Greece)
Peloponnesus in the south-western part of the Aegean is formed by a heterogeneous pile of alpine thrust sheets that was reworked by normal faulting from Upper Miocene to recent times. Upper
Exhumation of HP-rocks accompanied by low-angle normal faulting and associated detachment fault of Milos Island - Evidence from zircon fission-track thermochronology
Southward roll-back and slab retreat of the subducting African plate has been the cause of extension and magmatism in the Aegean since the Early Miocene. The Hellenic subduction system has shown a
Formation and fragmentation of a late Miocene supradetachment basin in central Crete: implications for exhumation mechanisms of high‐pressure rocks in the Aegean forearc
We present a new lithostratigraphy and chronology for the Miocene on central Crete, in the Aegean forearc. Continuous sedimentation started at ∼10.8 Ma in the E–W trending fluvio‐lacustrine Viannos
Map view restoration of Aegean–West Anatolian accretion and extension since the Eocene
The Aegean region (Greece, western Turkey) is one of the best studied continental extensional provinces. Here, we provide the first detailed kinematic restoration of the Aegean region since 35 Ma.
Normal Faulting Along the Kythira-Antikythira Strait, Southwest Hellenic Forearc, Greece
Upper-plate normal faults along forearcs often accumulate slip during >Mw 6 earthquakes. Such normal faults traverse the forearc of the Hellenic Subduction System (HSS) in Greece and are the focus of
Vertical-axis rotations accommodated along the Mid-Cycladic lineament on Paros Island in the extensional heart of the Aegean orocline (Greece)
The Aegean–west Anatolian orocline formed due to Neogene opposite rotations of its western and eastern limbs during opening of the Aegean back-arc basin. Stretching lineations in exhumed metamorphic
Rapid Exhumation of High-Pressure Metamorphic Rocks in Kythera-Peloponnese (Greece) Revealed by Apatite (U-Th)/He Thermochronology
Apatite (U-Th)/He and apatite fission-track cooling ages from high-pressure (HP) metamorphic rocks in the South Aegean forearc along the Kythera Strait (Kythera and southeastern Peloponnese) suggest
Santorini metamorphic basement is part of the metamorphic complex known as Cycladic Massif, which was formed during the subduction of the Mediterranean lithosphere underneath the Aegean microplate.


Structure and kinematics of Upper Cenozoic extensional detachment on Naxos and Paros (Cyclades Islands, Greece)
This paper presents a study of the ductile and brittle deformation on Naxos and Paros islands (Cyclades, Greece). Previous maps and studies of the two islands have shown that a major low-angle fault
Kinematics of the central Hellenides
Structural analysis along 24 cross sections crosscutting several windows in the central Hellenides provides the sense of nappe movements as well as the location of destroyed oceans lying between the

The mid-Miocene structural evolution of the metamorphic complex on Naxos involved deformation in a kilometre-scale low angle ductile shear zone. The structures described are consistent with
Exhumation Processes : Normal Faulting , Ductile Flow , and Erosion
Over the past 25 years, there has been a growing appreciation of the role that tectonic processes play in exhuming metamorphic rocks. This trend began with the discovery of highly attenuated crustal
Miocene high-pressure metamorphic rocks of Crete, Greece: rapid exhumation by buoyant escape
Abstract The pre-Neogene thrust sheets of Crete, Greece, accreted during Oligocene and Early Miocene time, can be divided into two main groups juxtaposed by a Miocene extensional detachment.
Miocene detachment in Crete and exhumation P‐T‐t paths of high‐pressure metamorphic rocks
A major problem posed by the geology of Crete is the horizontal contact of an upper unit without Miocene metamorphism onto a metamorphosed lower one with Early Miocene high pressure/low temperature
Detachment faults in the Aegean core complex of Ios, Cyclades, Greece
Abstract Several generations of detachment fault systems have been recognized in the Aegean metamorphic core complex of Ios, Cyclades, Greece. Multiple strands occur in each fault system, with
Late Cenozoic exhumation of the Cascadia accretionary wedge in the Olympic Mountains, northwest Washington State
The apatite fission-track method is used to determine the exhumation history of the Olympic subduction complex, an uplifted part of the modern Cascadia accretionary wedge. Fission-track ages are
