Because orogens and orogenies are manifestations of large-scale Earth processes, enhanced understanding of the geological factors involved in their genesis also provides important evidence bearing on the mechanisms of plate tectonics and the physical evolution of the planet.

What is the significance of the process of orogeny?

Orogeny is the primary mechanism by which mountains are formed on continents. An orogeny is an event that takes place at a convergent plate margin when plate motion compresses the margin. This leads to both structural deformation and compositional differentiation of the Earth's lithosphere (crust and uppermost mantle).

How long does an orogeny last?

The Orogeny, from the initial subduction of continental margin sediments to the end of postflip shortening, lasted ≈18 million years (my).
