Differences in tectonic style and kinematics orogenic belts can result from either multiphase or progressive deformation. In eastern Borborema Province, a regional shallow dipping foliation is multiply folded crosscut by transcurrent shear zones. Here, we investigate if these fabrics resulted diachronous deformational events single-phase The study area, the Feira Nova region, mostly comprises m...

Abstract A detailed geochronological study was conducted on zircons from a diorite sample of the Posets pluton (Axial Zone, Pyrenees). The extracted igneous constrain emplacement to 302 ± 2 Ma and 301 3 Ma, by means U–Pb sensitive high-resolution ion microprobe (SHRIMP) laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses, respectively. Considering syn- late-tectonic...

A variety of tectonic processes spread along the circum-Mediterranean orogenic belts driven by convergence major plates, episodes slab retreat and lateral vertical mantle flows. Here, we provide an updated view crustal stress strain-rate fields for Albanides belt in eastern Adria-Eurasia boundary. We framed a new geodetic-based source model 2019 Mw6.4 Durrёs earthquake light regional deformatio...

The Eocene tectonic evolution of the easternmost Caribbean Plate (CP) boundary, that is Lesser Antilles subduction zone (LASZ), debated. Recents works shed light on a peculiar period duality in arc/back-arc regions. A compressional-to-transpressional regime occurred north, while rifting and seafloor spreading Grenada basin to south. mechanism for this strong spatial variation its through time h...

[1] We use data from campaign and continuous GPS sites in southeast Alaska and the neighboring region of Canada to constrain a regional tectonic block model that estimates block angular velocities and derives a self‐consistent set of fault slip rates from the block motions. Present‐day tectonics in southeast Alaska is strongly influenced by the collision of the Yakutat block. Our model predicts...

[1] A series of sharp bends (oroclines) are recognized in the Paleozoic to early Mesozoic New England Orogen of eastern Australia. The exact geometry and origin of these bends is obscured by voluminous magmatism and is still debated. Here we present zircon U-Pb ages that confirm the lateral continuation of early Permian (296–288 Ma) granitoids and shed new light on the oroclinal structure. Orog...

Apatite helium thermochronometry provides new constraints on the tectonic history of a recently uplifted crystalline mass adjacent to the San Andreas fault. By documenting aspects of the low-temperature (40°1 00°C) thermal history of the tectonic blocks of the San Bernardino Mountains in southern California, we have placed new constraints on the magnitude and timing of uplift. Old helium ages (...

The late Pan-African Fawakhir, Urn Had and Urn Effein Granite Plutons in the Egyptian Central Eastern Desert are small, elongate to circular bodies of pink monzogranite and syenogranite, and grey monzodiorite. Structural investigation of the intrusive contacts of these plutons reveals marginal sub-horizontal intrusive sheets as magma injection along preexisting flat-lying structures including m...
