The enigmatic geodynamic processes involved in the India-Asia collision shape our understanding of uplift and deformation Tibetan Plateau subsequent changes land-sea distribution pattern, monsoon-arid environments biotic evolution Central-Eastern Asia. However, current models dealing with history exhibit significant discrepancies how, when where exactly India Asia occurred. Recently, we propose...

Abstract High-grade metamorphic rocks and crustal melts provide crucial evidence for growth differentiation of the continental crust, are widespread in collisional orogens. However, their importance evolution arcs remains poorly understood. Metamorphism related anatexis preserved margin Neo-Tethys ocean serves as a key natural laboratory to investigate this process. Along Neo-Tethyan arc margin...

Plate subduction continuously transports crustal materials with high-δ(18)O values down to the mantle wedge, where mantle peridotites are expected to achieve the high-δ(18)O features. Elevated δ(18)O values relative to the upper mantle value have been reported for magmas from some subduction zones. However, peridotites with δ(18)O values significantly higher than the well-defined upper mantle v...

In the Katha Range of central Myanmar, lithologic tracers and pressure-temperature-deformation-time data identify Cambro-Ordovician, Indian-affinity Tethyan Himalaya Series, located ∼700 km from their easternmost outcrop in S-Tibet, ∼450 Himalayan rocks Eastern Syntaxis. Metamorphism began at ∼65 Ma, peaked ∼45 Ma (∼510°C, 0.93 GPa), exhumation/cooling (∼25°C/Myr) occurred until ∼30 a subductio...

in the centeral iranian volcanic belt (civb), north-west of shahre-babak, in area of javazm, dehaj and khabr, about 20 plutonic porphyritic tonalitic to granodioritic masses (1-50 km2) are intruded into a varity of rock sequences from eocene to early miocene in age. tonalitic and granodioritic rocks are some part of dehaj-sardoieh belt and having early miocene age. the civb contains intrusive a...

The Middle East region represents a key site within the Tethyan domain where continental break-up, collision, backarc extension and escape tectonics are kinematically linked together. We perform global mantle circulation computations to test the role of slab pull and mantle upwellings as driving forces for the kinematics of the Arabia–Anatolia–Aegean (AAA) system, evaluating different boundary ...
