Volcanic mountain ranges represent thick segments of crust that formed by addition of thick piles of volcanic rocks, generally above a subduction zone. Examples of volcanic mountain chains include the Aleutians of Alaska, the Fossa Magna of Japan (including Mount Fuji), and the Cascades of the western United States (including Mount Saint Helens). These mountain belts are not formed primarily by deformation but by volcanism associated with subduction and plate tectonics. Many do have folds and faults, however, showing that there is overlap between fold and thrust types of mountain chains and volcanic ranges.
