In Chapter 6 we considered the simplest type of subduction-related magmatism produced as a consequence of the subduction of one oceanic plate beneath another. Now we shall focus our attention on the more complex case in which the overriding plate is a continental one. Magmas generated in this tectonic environment occur along the west coast of the Americas, Japan, Sumatra, Alaska, New Zealand and the Aegean (Fig. 7.1).
