41. There was a major orogeny in eastern Australia from 387 to 360 Ma. 42. These mountains were formed by an Orogeny effect of the North American Plate. 43. Generally the north was less deformed during the Hercynian orogeny than the south. 44. In most Phanerozoic orogenies many tectonic phases are distinguished. 45. The final stages of the Caledonian orogeny involved sinistral strike-slip faulting. 46. These sediments were in a large part later overprinted by the Variscan orogeny . 47. Its later movements were vital to the alpine cycle of the Pyrenean orogeny . 48. Rifting in the GLTZ began about at the end of the Algoman orogeny . 49. During the Penokean orogeny the Minnesota River Valley subprovince overrode the Superior province. 50. This stage of orogeny is called the Peruvian Phase.
