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.
Kodiak Shelf in the Gulf of Alaska – The geology of the Chugach National Forest is dominated by two major lithologic units, the Valdez Group (Late Cretaceous) and the Orca Group (Paleocene and Eocene). [15] The Valdez Group is part of a 2,200-km-long by 100-km-wide belt of Mesozoic accretionary complex rocks called the Chugach terrane. [16]
Accretion (coastal management), the process where coastal sediments return to the visible portion of the beach following storm erosion; Accretion (geology), the increase in size of a tectonic plate by addition of material along a convergent boundary; Accretionary wedge
Diagram of accretion and erosion of sediments in a coastal system. Black arrows indicate accretion, and white arrows indicate erosion. Sedimentary budgets are a coastal management tool used to analyze and describe the different sediment inputs (sources) and outputs (sinks) on the coasts, which is used to predict morphological change in any particular coastline over time.
The first is by frontal accretion, in which sediments are scraped off the downgoing plate and emplaced at the front of the accretionary prism. [2] As the accretionary wedge grows, older sediments further from the trench become increasingly lithified , and faults and other structural features are steepened by rotation towards the trench.

Eggs are one of the most versatile foods in the kitchen. Not only are they a classic breakfast item, but they can bind, emulsify, and leaven other ingredients, depending on the recipe.But they are ...
Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun, which also created the rest of the Solar System. Initially, Earth was molten due to extreme volcanism and frequent collisions with other bodies.
