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 million years ago (Mya) respectively, and ending with the last series of continental collisions in Triassic to early Jurassic times.
In the late Precambrian, the northeast margin of Baltica was deformed in the Timanide and Cadomide orogenies or the assembly of the Pannotia supercontinent.
[3] In the Ordovician-Silurian, Kazakhstania formed separately when subduction-driven growth accreted crust to a series of small, late Precambrian microcontinents.
In the early Late Carboniferous, Kazakhstania began to collide with Laurussia as the Palaeo-Uralian ocean subducted beneath the margins of the latter.
[3] The northern continuation of the Ural mountains, the Pay-Khoy-Novaya Zemlya foldbelt, is the result of the collision between Laurussia and Siberia in the Early Jurassic.
