WebAs summarized in Chapter 3, magma is formed at three main plate-tectonic settings: divergent boundaries (decompression melting), convergent boundaries (flux melting), and mantle plumes (decompression melting). Figure 4.3 The plate-tectonic settings of common types of volcanism. WebAccording to plate tectonics, the Earth's crust is comprised of over a dozen rigid slabs, or plates. As these plates move over the Earth's fluid mantle, they interact with each other, forming plate boundaries or zones. Areas where plates are colliding form convergent boundaries, and areas where plates are ...
