Tectonic phase

A tectonic phase or deformation phase is in structural geology and petrology a phase in which tectonic movement or metamorphism took place. Tectonic phases can be extensional or compressional in nature.

When numerous subsequent compressional tectonic phases share the same geodynamic cause (usually some plate tectonic mechanism) this is called an orogeny. During an orogeny tectonic phases lead to mountain building, which causes deformation and metamorphism of rocks. In most Phanerozoic orogenies many tectonic phases are distinguished.
