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. WebMar 23, 2014 · The accretionary mountain belts (orogens) that form at these convergent plate margins have been the principal sites of lateral continental growth through Earth’s history. Modern examples of accretionary margins are the North American Cordilleras and southwest Pacific subduction zones.
