The Late Paleozoic Structural Evolution of the Magnitogorsk Megazone in the Southern Urals

摘要

Various models of the evolution of the southern Urals at the stage of the Late Paleozoic collision of the East European and Kazakhstan continents have been proposed [3-5, 7, and others]. The diversity of geody-namic models is caused by poor knowledge of regional tectonics in terms of structural geology. The results of regional structural and tectonophysical studies in the Magnitogorsk Megazone allowed us to recognize and characterize two stages of the Late Paleozoic (post-Devonian) tectonic deformations: (1) thrusting in the Middle Carboniferous and (2) strike-slip faulting in the left-lateral transpression regime in the Middle Carboniferous-Permian.
