If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older,denser plate will subduct beneath the less dense plate. Where is an example of an oceanic oceanic convergent plate boundary? We continue our trip upwestern North Americato find a convergent plate ...
The vast majority of volcanism on Earth occurs at spreading and convergent plate boundaries (e.g., mid-oceanic ridges and subduction zones), whereas there are also volcanoes far from these plate boundaries, such as the Changbaishan-Tianchi volcano within the continent of northeastern Asia (e.g....

Evolution of shallow, crustal thermal structure from subduction to collision: An example from Taiwan We study crustal thermal evolution by examining heat flow patterns along a convergent boundary from a young subduction zone to a more structurally mature c... Wu-Cheng,Chi$Donald,L.,... - 《Gsa...
This difference in number of events was proposed to be due to the presence of a serpentinized mantle layer overlying a pristine mantle layer located below 30–35 km down to the base of the lithosphere located at ~60 km, with a large stress drop occurring at the boundary between the ...

1. Introduction Ophiolites, preserved as obducted slivers of ancient oceanic litho- sphere in Precambrian and Phanerozoic orogenic belts and on continen- tal margins, provide the most conspicuous and robust perspectives on intraoceanic divergent and convergent margin tectonics, mantle hetero- geneity,...
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 pr
The Kuroshio transport east of the LS is convergent in the meridional direction and divergent in the zonal direction. When strong CEs interact with the Kuroshio, the convergence is greatly enhanced, and the transport at the northern boundary changes from 0.026 Sv northward to 0.002 Sv ...
