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
Kaikoura Orogeny million years ago to the present day the rate of uplift has accelerated. Oligoclase and biotite schist have also been pushed to the surface of the Earth. In total about 20 kilometres of uplift has taken place during the Kaikoura Orogeny but most of this has been eroded away. Kaikoura Orogeny The Kaikoura Orogeny is a New Zealand orogeny that has given birth to the Southern Alps. It began 25 million years ago along the Alpine Fault. In this orogeny, the Southern Alps are being formed because the Pacific Plate is colliding with the Australian Plate, with a predominant oblique
