Prism (geology) - Accretionary Prism
... An accretionary prism or accretionary wedge is formed from sediments that are accreted onto the non-subducting tectonic plate at a convergent plate boundary ... Most of the material in the accretionary wedge consists of marine sediments scraped off from the downgoing slab of oceanic crust but in some cases includes the erosional products ...

Most of the material in the accretionary wedge consists of marine sediments scraped off from the downgoing slab of oceanic crust but in some cases includes the erosional products of volcanic ...
Accretionary Wedge - Geometry
... The topographic expression of the accretionary wedge forms a lip, which may dam basins of accumulated materials that, otherwise, would be transported into the trench from the ... Accretionary wedges are the home of mélange, intensely deformed packages of rocks that lack coherent internal layering and coherent internal order ... The internal structure of an accretionary wedge is similar to that found in a thin-skinned foreland thrust belt ...
Accretionary Wedge - Examples

Materials Within An Accretionary Wedge
... Accretionary wedges and accreted terranes are not equivalent to tectonic plates, but rather are associated with tectonic plates and accrete as a result of tectonic collision ... Materials incorporated in accretionary wedges include Ocean-floor basalts – typically seamounts scraped off the subducting plate Pelagic sediments – typically immediately overlying oceanic ... are small basins located in surface depression on the accretionary prism ...
