Following the successful rifting sessions led by the TS Division over the last years, this session aims to gather contributions that focus on rifts and rifted margins (magma-poor and magma-rich), their architecture and evolution. We aim to discuss the offshore crustal, volcanic and sedimentary architecture of rifted margins, and also the onshore connection. We would like to bring together contributions on worldwide examples and from a broad range of disciplines, such as seismic refraction and reflection studies, geology, geophysics, and sedimentology. Special emphasis will be put on contributions dealing with key questions such as:
* What are the crustal geometry and evolution, and associated sedimentary patterns, of distal rifted margins?
* What are the structural characteristics associated with drastic crustal thinning (the necking domain)?
* What is hyperextension?
* What are the basement and sedimentary geometries characteristic of hyperextension and of mantle exhumation?
* What is the magmatic history of rifted margins? And how does the magmatic history fit with its structural evolution?
* Can observations and models developped for magma poor margins be extended to magma rich cases?
* What is breakup? what is the role of magma in rift evolution?
* What are the onshore and offshore records of uplift/subsidence and mass transfer?
* How to characterize the interactions between surface processes, tectonics and climate during margin evolution?

We are excited to announce our solicited presenters: Cindy Ebinger and Gianreto Manatschal!
