WebA magmatic system is the site of melting, the pathway of magma migration and the site of crystallisation within a specific geological and tectonic environment. A magmatic system will extend from the mantle to the upper crust in most cases (Figure 2.1). A volcanic arc (also known as a magmatic arc ) is a belt of volcanoes formed above a subducting oceanic tectonic plate, with the belt arranged in an arc shape as seen from above. Volcanic arcs typically parallel an oceanic trench, with the arc located further from the subducting plate than the trench. … See more A volcanic arc is part of an arc-trench complex, which is the part of a subduction zone that is visible at the Earth's surface.
