Accretion (geology) - Wikipedia, the free encyclopedia

Accretion is a process by which material is added to a tectonic plate or a landmass. This material may be sediment, volcanic arcs, seamounts or other igneous features. There are two types of geologic...

The accretion of plateaus during subduction of oceanic plates may be responsible for mountain building comparable to that produced by the collision of continents. ...

Uplift of this magnitude near the edge of the continent is interpreted as representing an early stage of continental accretion, possibly as a result of compression normal to the continental margin. The average maximum horizontal component of this accretion would be about 16 kilometers.

The steep boundary is not evident in the seismic data and highlights the utility of MT in defining fundamental crustal boundaries.

Future closure of the Aleutian–Bering Sea region, either northward toward the continent or southward toward the Aleutian Arc, would structurally mold new continental crust to the North American plate. The resulting "Beringian orogen" would be constructed of a collage of suspect terranes.

Continental crust was constructed from recycled continental detritus and juvenile material in an oceanic setting as subduction alternated from phases of roll-back to phases of intense coupling. Recent structural syntheses and detailed geochronology has redefined the timing and nature of the Delamerian and Lachlan orogenies.

THE study of palæomagnetism has necessitated the contemplation of continental drift and the most plausible explanation appears to be convection in the mantle1,2. It has been assumed that the convection is thermal, being maintained by heat from the core.
