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....
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 Bulletin》 被引量: 38发表: 2008年 Seismic structure of the ocean crust This paper evaluates the...
by the Sierra Nevada in the North Cordillera, which shows a sequence of crystallization from high-Mg pyroxenites (with minor Grt) to low-Mg, garnet- or plagioclase-rich pyroxenite depending on pressure23. These results indicate that the pre-collisional mafic rocks were derived from wet fractional...
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,...
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 ...

Convergent morphology of the plankton represents adaptations for suspension in the water column, for movement within this water mass to increase nutrient uptake, and for protection against grazing or predation. Necessary attributes for cosmopolitan species include eurythermy and euryhalinity. The ...
Comparison of numerical results to existing natural examples suggests that in nature, STEP-faults follow convergent paths that could be controlled by intense fractures weakening due to deep water penetration into the relatively cold oceanic lithosphere of the present-day Earth....
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 ...
