2.7 Continental Collisions: Building the Himalayas, the Indian plate meets the Eurasian plate When a slab of oceanic lithosphere subducts beneath a continental margin, an Andean type mountain belt develops. If the subducting plate also contains a continent, continued subduction …
2.6 Sierra Nevada and Coast Ranges, What is a Batholith? During the Jurassic, when the North Atlantic began to open, a subduction zone formed along the western margin of the North American Plate. Evidence for this episode of subduction is …
