How does magma form over an active subduction zone? How are igneous rocks formed from a subduction zone? How is basaltic magma transformed into felsic magma? How are volcanoes formed by plate tectonics? How does water create magma during subduction at a divergent boundary? In other words, how...
The most complete magmatic record of subduction initiation has been found at the Izu-Bonin-Mariana subduction zone (IBM)4. Dredging and diving in this region5 suggests that subduction initiation along the full length of the arc started with the production of a magma closely resembling those formed...

They are BABBs and their primary magma was derived from a source region between EMI and EMII that was affected by continental crustal contamination as well as subduction-zone metasomatism. Combined with previous studies, we suggest that the onset of subduction of the Paleo-Pacific Plate was in ...

Subduction is the core process of plate tectonics. The mantle wedge in subduction-zone systems represents a key tectonic unit, playing a significant role in material cycling and energy exchange between Earth’s layers. This study summarizes research prog
Much debate exists concerning mechanisms of crustal material transfer from subducting slab to overlying mantle. Formation of mélange rocks by physical mixing of slab components within subduction plate interface is predicted to transfer their composition
