Peculiarities of the Kinematics of the South Uralian Suture Zones as a Cause of the Formation of the Convergent Structure of the East Uralian Megazone

摘要

The structure of the suture zones surrounding the East Uralian megazone in the South Urals is reviewed. The analysis of mesoscale structures allowed us to prove their strike—slip nature. Their kinematics changed from left-lateral in the Early Carboniferous into right-lateral in the Mesozoic. The age of these dislocations was determined after the age of synkinematic intrusions. The suture zones have divergent structures in contrast to the convergent East Uralian megazone that is located between them.
