Arc-continent collision zones form where an oceanic plate bearing an island arc converges with and is thrust beneath a continental margin, generating complex deformation, uplift and seismicity. These ...

Convergent plate boundaries, where one lithospheric plate descends beneath another, drive subduction and ultimately lead to arc-continent collision. In classical subduction settings, the downgoing ...

Some 445 million years ago, the Eastern US (extreme left) sat in the tropics, where an island arc-continental collision created the Appalachian Mountains. That collision uplifted rocks that absorbed ...
