Top-to-the-S vs top-to-the-N extensional shearing in the southern Cyclades, Aegean Sea, Greece: new geochronologic data Open
The geometry of large-scale extensional deformation in the southwestern Cyclades archipelago is a controversially discussed issue. Recent studies suggest a bivergent (i.e., coeval top-to-the-S and top-to-the-N shear) geometry of early Mioc…

Was the Formation of the North Anatolian Fault Influenced by the Aegean Extension? Open
The North Anatolian Fault (NAF), one of the most prominent plate boundary continental fault systems on Earth, facilitates the westward movement of the Anatolian microplate into the Aegean region. The temporal and spatial evolution of the N…

The temporal and kinematic constraints on the early Alpine orogen: insights from Rb–Sr geochronology and geological mapping of the Avers nappe (Eastern Swiss-Alps) Open
Understanding temporal shifts of thrust transport direction and the interplay between thrusting and normal faulting during mountain building is important for better understanding orogeny. Current tectonic models of the Alps envisage Cretac…

First steps of LA-ICPMS U-Pb magnetite geochronology Open
It is well known that the density of metamorphic reactions occurring in subduction zones, due to intense fluid-melt activity, is very high. One of the minerals resulting from all these reactions, present both in the downgoing slab and in t…

The complex continental margin of NE Oman: Fault-gouge dating of the Wadi Kabir Fault at the northern margin of the Saih Hatat window, Sultanate of Oman, and its wider implications Open
The complex structural geometry along the northern continental margin of Oman formed during polyphase deformation from the late Cretaceous to the Miocene. We focus on the kinematics and tectonics of the Wadi Kabir Fault, which represents a…

Slab reequilibration and slab roll back timing in the Cyclades: Evidence from garnet diffusion and P-T estimates (Naxos, Greece) Open
Understanding the mechanisms of mountain building and its destruction poses significant challenges. Following subduction of a slab, an increase in the subduction rate and/or a decrease of the convergence rate, may lead to slab rollback. Du…

Constraining the <500 Ka faulting history of the Central Taurides above the Cyprus Subduction Zone: Insights from U-Th carbonate geochronology Open
The Central Taurides is located at the southern margin of the Central Anatolian Plateau with a high relief up to a 2 km topography. This plateau margin rises in the upper plate north of the Cyprus Arc where the African Plate subducts benea…

The Samail subduction zone dilemma: Geochronology of high-pressure rocks from the Saih Hatat window, Oman, reveals juxtaposition of two subduction zones with contrasting thermal histories Open
The Samail Ophiolite in the Oman Mountains formed at a Cretaceous subduction zone that was part of a wider Neo-Tethys plate-boundary system. The original configuration and evolution of this plate-boundary system is hidden in a structurally…

Comment on gchron-2023-11 Open
Abstract. The island of Patmos, in the eastern Aegean Sea, consists almost entirely of late Miocene to Pliocene volcanic rocks. The magmatism in the Aegean is governed by subduction of the African plate below the Eurasian plate, back-arc e…

Some Like It Cold: The “Conundrum of Samail” Revisited Open
Most tectonic models consider that the “Samail subduction zone” was the only subduction zone at the mid‐Cretaceous convergent Arabian margin. We report four new Rb‐Sr multimineral isochron ages from high‐pressure (HP) rocks and a major she…

Petrochronology of polygenetic white micas (Naxos, Greece) Open
Naxos in the Greek Cyclades preserves a type example of polymetamorphism. The southern and northern parts of the island record different Tertiary P–T histories between Eocene and Miocene times, including a blueschist facies event, one or m…

Nappe Imbrication Within the Phyllite‐Quartzite Unit of West Crete: Implications for Sustained High‐Pressure Metamorphism in the Hellenide Subduction Orogen, Greece Open
We report four K‐Ar fault‐gouge and eight U‐Pb calcite ages from the high‐pressure Phyllite‐Quartzite Unit (PQ) and the overlying, strongly thinned non‐high‐pressure Tripolitza and Pindos units of western Crete, Greece. We relate consisten…

Deformation of the European Plate (58-0 Ma): Evidence from Calcite Twinning Strains Open
We present a data set of calcite twinning strain results (n = 209 samples; 9919 measured calcite twins) from the internal Alpine nappes northwestward across the Alps and Alpine foreland to the older extensional margin along the Atlantic co…

The Cycladic Blueschist Unit of the Hellenic subduction orogen: Protracted high-pressure metamorphism, decompression and reimbrication of a diachronous nappe stack Open
We discuss the assembly and tectonochronology of the Cycladic Blueschist Unit (CBU) in the central Aegean Sea region, Greece, as a composite, subduction-related, high-pressure (blueschist to eclogite facies) stack of nappes. Our work is ba…

Geometry and Kinematics of Bivergent Extension in the Southern Cycladic Archipelago: Constraining an Extensional Hinge Zone on Sikinos Island, Aegean Sea, Greece Open
We report the results of a field study on Sikinos Island in the Aegean extensional province of Greece and propose a hinge zone controlling incipient bivergent extension in the southern Cyclades. A first deformation event led to top‐S thrus…

The importance of tangential motion in the Central Alps: Kinematic analysis and Rb Sr dating of mylonitic rocks from the Pennine nappes in the eastern Central Alps Open
We discuss the important role of tangential stretching in the Central Alps highlighting that the Alps are a truly three-dimensional orogen. A review of pressure-temperature (P-T) conditions allows us to define three major breaks in metamor…
