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
San Rafael orogeny the San Rafael orogeny. San Rafael orogeny The San Rafael orogeny was an orogeny that affected parts of western Argentina and Chile during the Late Paleozoic. The resulting orogenic belt has a NW-NNW curved form. The San Rafael orogeny might have been linked with the roughly contemporary Gondwanide orogeny of eastern Argentina. Parts of the Choiyoi Group sediments were deformed by the San Rafael orogeny. During the Neogene ancient faults related to the San Rafael orogeny conditioned the geometry of the blocks affected by the Andean orogeny. Some of the plutons of the Elqui-Limarí Batholith were emplaced a context of
