T51F:
Rifts and Passive Margins: Tectonics, Dynamics, Processes IV Posters


Session ID#: 7198

Session Description:
This session presents recent advances on rifts and passive margins from geological and geophysical studies that are based on seismic interpretation, field geological data, plate reconstructions, sedimentology, and modeling.

We aim to assemble presentations on basin, regional and global scale that provide new insight on rift evolution in terms of inheritance and strain localization, fault interaction and stratigraphy, partial melting and volcanism, surface stress evolution, tectonics-climate interaction, small-scale convection, driving forces, and rift-to-drift transition. Most rifts feature significant along-strike structural variations. We therefore particularly encourage abstract submission on 2D investigations with regional perspective, 3D seismic arrays, as well as 3D analogue and numerical experiments.

Special emphasis will be put on contributions that develop an integrated picture by bridging multiple spatial or temporal scales or by combining results from active rifts, failed rift arms, passive margins or obducted rifted margins.
