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...

Gongga Shan (GGS) is the highest mountain on eastern margin of Tibetan Plateau. However, mechanism for uplift still unclear due to a lack detailed geophysical studies. Inversion an array magnetotelluric data at 120 sites produced 3D resistivity model that revealed GGS massif characterized by high upper crust underlain westward dipping resistor middle crustal depths interpreted as underthrust Ya...

Abstract The Southern Andes are regarded as a typical subduction orogen formed by oblique plate convergence. However, there is considerable uncertainty to how deformation kinematically partitioned in the upper plate. Here we use analogue experiments conducted MultiBox (Multifunctional Box) apparatus investigate dextral transpression between 34 °S and 42 °S. We find that our models caused mainly...

Based on new structural, petrological and U-Th-Pb geochronological data, a reappraisal of the Variscan tectono-metamorphic history Pelvoux Massif (External Crystalline Massif, French Alps) is proposed with aim to understand flow pattern kinematics partially molten crust Eastern Shear Zone. The consists high-grade metamorphic rocks middle lower crust, mostly migmatites, that record prominent syn...

Metamorphic and various intrusive rocks in the Urmia area are located in a transpressed active continental margin. These complexes in the Zagros orogen were deformed during an oblique convergence scenario between the Arabian and Sanandaj–Sirjan blocks in NW Iran. The Urmia area contains both NW-SE striking dextral strike-slip and SW verging NE dipping ductile reverse shear fabrics. Ductile shea...

Compressive and extensive horsetails are common structures on the lateral termination of brittle strike-slip faults, which forms within the shallow continental crust. Here we report another possibility, the lateral termination of a brittle strike-slip fault in a formation-parallel low-temperature ductile shear zone within sulphatic, gypsum-dominated evaporites. In the Southern Alps, over a dist...

In segmented paleorift systems such as the Pripyat–Dnieper–Donetsk aulacogen, which penetrate deep into continent from side of paleoocean margin and most often close here, each segment represents an autonomous structure lithosphere. The presented article shows that tectonic position Pripyat western closing indicated aulacogen was due to a change in intensity syn-rift plate-tectonic processes ex...
