Accretion (geology)

Oceanic-continental convergence and creation of accretionary wedge
Stages of accretion through time with accretionary wedge and volcanic island arc

In geology, accretion is a process by which material is added to a tectonic plate at a subduction zone, frequently on the edge of existing continental landmasses. The added material may be sediment, volcanic arcs, seamounts, oceanic crust or other igneous features.[1][2][3]
