WebThe accretion or growth of continents is referred here to the enlargement of the continental lithosphere, which includes both lateral expansion and vertical accretion. Lateral expansion happens along convergent plate margins where different kinds of terranes such as island arcs, seamounts and continental fragments attach to the host continent. WebChelogenic cycles 1, terrane accretion 2, or continental collision are among fundamental processes that allow the preservation of the archives of crustal evolution 3 – 6. Particularly, terrane accretion is one of the main processes for lateral continental growth through Earth’s history 6 – 9 .
