Abstract:Emplacement of the southern Urals accretionary complex onto the East European Craton involved off-scraping of shallow marine limestones from the continental margin and their underplating to the base of the accretionary complex during the final stages of arc-continent collision. These limestones underwent localized ductile to semi-brittle deformation at upper-crustal levels, at temperatures close to 200 °C. Field observations, macroscopic fabric elements and crystallographic preferre...
