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.
Accession might also be (from Latin accedere, to go to, approach), in law, a method of acquiring property adopted from Roman law (see: accessio), by which, in things that have a close connection with or dependence on one another, the property of the principal draws after it the property of the accessory, according to the principle, accessio cedet principali.
However, as a river gradually changes through accretion, the boundary changes with it. To prove that a change was avulsion and not accretion, it is sufficient, at least under Oklahoma law, for the owner of land that was washed away to point out approximately as much land added to the opposite bank as washed away from his bank.

Alluvion, is a Roman law method of acquisition of heritable property (land). The typical cause is sediment deposited by a river.This sediment, legally termed the accessory, accreses (i.e., merges with) a piece of land, the principal (operating a subtype of the Roman mode of acquisition by accession) and thus accedes to the ownership of the principal land over time.
Melt production and accretion of melt onto continental crust in a subduction zone [1]. A subduction zone is a region of the Earth's crust where one tectonic plate moves under another tectonic plate; oceanic crust gets recycled back into the mantle and continental crust gets produced by the formation of arc magmas.
An example of an erosional avulsion is the 2006 avulsion of the Suncook River in New Hampshire, in which heavy rains caused flow levels to rise. The river level backed up behind an old mill dam, which produced a shallowly-sloping pool that overtopped a sand and gravel quarry, connected with a downstream section of channel, and cut a new shorter ...
Avulsion (river) – Rapid abandonment of a river channel and formation of a new channel; Progradation – Growth of a river delta into the sea over time; Sedimentary basin – Regions of long-term subsidence creating space for infilling by sediments
Areas where more particles are dropped are called alluvial or flood plains, and the dropped particles are called alluvium. Even small streams make alluvial deposits, but it is in floodplains and deltas of large rivers that large, geologically-significant alluvial deposits are found.
