Definition of orogeny in English:
orogeny
noun ɒˈrɒdʒəniˌɔˈrɑdʒ(ə)ni
mass nounGeology A process in which a section of the earth's crust is folded and deformed by lateral compression to form a mountain range.
present rates of denudation and orogeny
count noun the Hercynian and Alpine orogenies
Example sentencesExamples
- Granitoids are abundant in the Iberian Massif, and result from melting of the continental crust thickened during the Variscan orogeny.
- The tectonic events began with the Penobscottian orogeny in the Cambrian Period that affected northwestern to north-central Maine.
- Together with the Appalachian, Caledonian and Variscan orogens, the Uralian orogeny contributed to the assembly of the late Palaeozoic supercontinent of Pangaea.
- The Dalradian rocks in Arran were initially folded during the Caledonian orogeny into a recumbent structure known as the Aberfoyle synform.
- Around Britain a series of deep seismic traverses has revealed many of the structures produced during the Caledonian orogeny and other earth movements that are continued out over the continental shelf.

Example sentencesExamples

- This, he suggested, was an intentional mechanism for generating the prodigious amounts of heat necessary for such things as rapid orogenesis, the rapid melting of protoliths, etc.

- In north-west Scotland, for example, the lithosphere thickened during Caledonian orogenesis began to collapse under the influence of gravity from Early Devonian times.

Geology The Uralide orogen differs from other Palaeozoic orogenic belts in that it has a crustal root, which appears to be absent in the Caledonide, Variscide and Appalachian orogens.
Example sentencesExamples
- This event is also associated with production of late orogenic granite magma.
- Recent studies of Proterozoic orogenic belts have shown that they may be underlain, at mid to lower crustal levels, by keels of Archaean crust.
- Previous work that indicates Late Cretaceous Palaeogene orogenic activity is presented first.
- It is suggested that the emplacement of most post-tectonic plutons of this part of the Variscan orogenic belt may have been controlled by the late extensional collapse of the Iberian Massif.
