orogeny
(redirected from Orogenic belt)

    Also found in: Wikipedia 0.07 sec.

orogeny

Mountain-building event, generally one that occurs in a geosyncline. Orogeny tends to occur during a relatively short geologic time frame. It is usually accompanied by folding and faulting of strata and by the deposition of sediments in areas adjacent to the orogenic belt. Orogenies may result from continental collisions, the underthrusting of continents by oceanic plates, the overriding of oceanic ridges by continents, and other causes. See also Acadian orogeny, Alleghenian orogeny, Alpine orogeny, Laramide orogeny, Taconic orogeny.

Classic Soviet studies systematically linked metallogenic periods to orogenic phases (Smirnov 1988); yet, it has become apparent that there are discrepancies between the productivity of certain orogenic belts, which are difficult to explain (Goldfarb et al.
