In contrast to continent/continent collision, arc-continent collision generates very short-lived orogeny because the buoyancy-driven impedance of the subduction of continental lithosphere, accompanied by arc/suprasubduction-zone ophiolite obduction, is relieved by subduction polarity reversal (flip). This tectonic principle is illustrated by the early Ordovician Grampian Orogeny in the British ...

The Karakoram Terrane (KT) represents the southern margin of Eurasian Plate, mainly consisting Late Jurassic-Early Cretaceous subduction-related granites and post-collisional Miocene leucogranites, which intrude Neo-Proterozoic basement. We report for first time existence Cryogenian KT basement as recorded from geochemistry geochronology tonalite gneiss (ca. 806 Ma) in southeastern terrane, NW ...

This paper presents evidence on Mesozoic inversion of basin bounding faults within the Taleqan-Gajereh-Lar Paleograben (TGLP) in Central Alborz Range. For this purpose, well documented stratigraphy data across the TGLP together with the new acquired structural data on the geometry and kinematics of the paleograben basin bounding faults are utilized. The TGLP has evolved through the Early and Mi...

khoroslodaghlocated in northwestern of iran and south of moghan plain in ardabil province. these mountainsare from azarbyjan mountains unit and are separated from caucasus and talesh mountains in azarbyjan republic. study area was folded by upper pliocene and quaternary orogeny. pliocene orogeny was severe but quaternary folded was calm. afterward orogeny movements and folding, invertedrelief (...
