Structure and evolution of the Atlantic passive margins: A review of existing rifting models from wide-angle seismic data and kinematic reconstruction

Deep seismic data and plate kinematic reconstructions help understand the mechanisms of rifting opening new oceans, basic principles tectonic cycles. In this study, available deep wide-angle velocity models from Atlantic margins are reviewed used to define conjugate model pairs. The main objective was study question how magma-rich magma-poor develop role inheritance in break-up. We also studied mechanism formation origin transform marginal plateaus, which typically found at border two ocean basins different ages mostly characterized by least one volcanic phase during their formation. results include comparison crustal thickness, oceanic thickness influence volcanism along margins. profiles image degrees asymmetry Margin rifts. Marginal plateaus might form when stops barriers leading accumulation heat mantle increased directly before or after halting rifting.
