Plate tectonic model of the South Urals development

摘要: Abstract The Uralian Fold Belt originated due to the East European-Kazakhstan continental collision in Late Paleozoic-Early Triassic. paleo-ocean existed from Ordovician Early Carboniferous. It evolved along Western Pacific pattern with island arcs and subduction zones moving oceanwards European margin leaving newly opened back-arc basins behind Silurian Middle Devonian. A fossil spreading similar present one can be reconstructed for Mugodjarian basin rate of 5 cm/yr depth basaltic eruption 3000 m. Since Devonian, closure has begun. zone flipped over under Kazakhstan continent, remnants an oceanic floor were completely consumed before After that began which lasted nearly 90 Ma. As a result, distinct linear shape nappe structure Urals formed.
