Uralian orogeny Uralian orogeny The Uralian orogeny refers to the long series of linear deformation and mountain building events that raised the Ural Mountains, starting in the Late Carboniferous and Permian periods of the Palaeozoic Era, c. 323–299 and 299–251 Mya respectively, and ending with the last series of continental collisions in Triassic to early Jurassic times. In terms of plate tectonics, the Uralian orogeny resulted from a southwestern movement of the Siberian plate, catching a smaller landmass, Kazakhstania, between it and the nearly completely assembled supercontinent, Pangaea. The mountains of Eastern Europe on the paleocontinent Laurussia, and those of Western Siberia
Pan-African orogeny collisions of several continental blocks. Furthermore, the Pan-African events are contemporaneous with the Cadomian orogeny in Europe and the Baikalian orogeny in Asia, and crust from these areas were probably part of Pannotia (i.e. Gondwana when it first formed) during the Precambrian. Attempts to correlate the African Pan-African belts with the South American Brasiliano belts on the other side of the Atlantic has in many cases been problematic. Orogenic belts comprising the Pan-African system include: Pan-African orogeny The Pan-African orogeny was a series of major Neoproterozoic orogenic events which related to the formation of the supercontinents Gondwana and Pannotia about
