The Alps are, in a geological sense, a collisional orogen resulting from the collision of the European continent(“Europe”) with the Adriatic continent (“Adria”, also termed “Apulia”) after the subduction of intervening ocean basins. The collision took place in the Tertiary but was preceded by other collision events in the Cretaceous period. The first overthrusting processes during the Alpine Orogeny already took place in the Jurassic, ca. 160 million years (Ma) before present. Today, the Earth’s crust is still being shortened in the eastern part of the Alps. Altogether, the Alpine Orogeny thus lasted from Jurassic until Recent. The Alps are also called a thrust belt because large parts of the Alps are formed by thrust sheets (nappes).
