Deformational phases of lesser importance followed the Pyrenean Main Phase, all contributing to the final appearance of the orogen.
32.
The orogen was squeezed into an asymmetric fan-like structure due to the aborted subduction of Iberia underneath Aquitania.
33.
The first geologists to study the orogen where Wilhelm Ramsay and Tschernyschev who published works in 1899 and 1901 respectively.
34.
In addition to orogeny, the orogen ( once formed ) is subject to other processes, such as sedimentation and erosion.
35.
The " Caledonian Orogen " resulted from these events and various others that are part of its peculiar orogenic cycle.
36.
It has been suggested that the southern Iapetus Ocean closed during a continental collision between Laurentia and Famatinian orogen exposed in Argentina.
37.
The current orogenic event is causing parts of the Asian continent to deform westward and eastward on either side of the orogen.
38.
These AMCG rocks are somewhat anomalous throughout the Grenville orogen, there is no known orogenic event which immediately predates their emplacement.
39.
It extends east from Minnesota to the Grenville orogen near Lake Huron and south to the Animikie Group and Marquette Range Supergroup.
40.
It is bounded on the west and north by the Proterozoic Trans-Hudson orogen which separates it from the Nain cratons.
