Causes (1), (3) and (4) could operate in concert as a subduction trench converged on a rifted margin.
Contrary to the suggestion of a relationship between ridge subduction and compression, the main result of this collision has been fast uplift and extensional tectonism.
However, the geochemical data are consistent with derivation of magmas from a mantle source modified by subduction processes.
The second model involves derivation of the melts from a depleted lithospheric mantle source which was contaminated by subduction components.
Subduction of dense cold plates into the mantle leads to plate tectonics.
A physical model for the volume and composition of melt produced by hydrous fluxing above subduction zones.
Lithospheric buoyancy and collisional orogenesis: subduction of oceanic plateaus, continental margins, island arcs, spreading ridges, and seamounts.
With continuing subduction the pelagic sediments might have been dragged beneath the accretionary prism leading to compaction and expulsion of large amounts of pore fluids.
