Knowledge and Geological techniques Comments understanding and skills The various elements of the rock cycle may be linked directly to plate tectonic processes: igneous basaltic – magmatism at oceanic spreading centres; basaltic and andesitic magmatism at convergent margins; granitic magmas in orogenic belts sedimentary – erosional processes and depositional environments influenced by tectonic movements regional metamorphism in subduction zones and orogenic belts at plate boundaries.
