orogenyMountain-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. How to thank TFD for its existence?

Nonetheless, much remains to be accomplished in this area, particularly in our understanding of the vertical distribution of deposits within continents, and their link to the orogenic cycle. Scientists got their first inklings that cratonic plates differ from plates under oceans and the younger, deformed parts of continents, called orogenic zones, in the 1960s. He published widely on Archaean evolution, the nature and genesis of komatiite-hosted Ni-Cu and orogenic gold deposits, global metallogeny and conceptual targeting of mineral deposits. |
