Subduction zones are tectonic expressions of convergent plate margins,where crustal rocks descend into and interact with the overlying mantle wedge.hey are the geodynamic system that produces maic arc volcanics above oceanic subduction zones but high-to ultrahigh-pressure metamorphic rocks in continental...

Generation of continental crust in collision zones reflect the interplay between oceanic subduction and continental collision. The Gangdese continental crust in southern Tibet developed during subduction of the Neo-Tethyan oceanic slab in the Mesozoic prior to reworking during the India-Asia collision in ...

The results indicate only low geothermal gradients corresponding to hot subduction zones produce Ba-rich TTG, thus Ba represents a proxy for the onset of subduction. We then identify statistically significant increases in the Ba contents of TTG suites worldwide as recording the diachronous onset of ...
We quantitatively investigate the relation between nappe stacking and subduction in the Aegean region. If nappe stacking is the result of the decoupling of upper-crustal parts (5–10 km thick) from subducting lithosphere, then the amount of convergence estimated from balancing the nappe stack provide...

One way to thicken mafic crust in the late Archean is by plate jams in subduction zones caused by the greater buoyancy of oceanic plates produced during a late Archean global thermal event. Modern subduction zones became widespread in the early Paleoproterozoic as magma production shifted from ...
. Modern continental crust is largely formed from wet and oxidizing arc magmas at subduction zones, in which oceanic lithosphere and water recycle into the mantle8,9,10. The magmatic H2O content and redox state of ancient rocks that constitute the early continental crust, however, are difficult...
