Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges.
The most dramatic orogenic belt on the planet is the one between the African plate and the Indo-Australian plate on one side (to the south) and the Eurasian plate on the other side (to the north). This belt runs from New Zealand in the east-south-east, through Indonesia , along the Himalayas , through the Middle East up to the Mediterranean in ...
An orogenic belt, orogen, or mobile belt, [a] is a zone of Earth's crust affected by orogeny. [2] An orogenic belt develops when a continental plate crumples and is uplifted to form one or more mountain ranges ; this involves a series of geological processes collectively called orogenesis .
The Alpine orogeny is caused by the continents Africa, Arabia and India and the small Cimmerian Plate colliding (from the south) with Eurasia in the north. Convergent movements between the tectonic plates (the African Plate, the Arabian Plate and the Indian Plate from the south, the Eurasian Plate and the Anatolian Sub-Plate from the north, and many smaller plates and microplates) had already ...
Map of a north-south sea-parallel pattern of rock ages in western Colombia. This pattern is a result of the Andean orogeny. Tectonic blocks of continental crust that had separated from northwestern South America in the Jurassic re-joined the continent in the Late Cretaceous by colliding obliquely with it. [6]
