The integrated study of field (young, and ancient analogues preserved in orogenic systems), seismic reflection/refraction, gravity/magnetics, well data (exploration and IODP), analogue and thermo-mechanical modelling approaches have greatly improved our understanding of the processes that influence and modify the architecture (crustal, magmatic, sedimentary, structural and thermal) of the distal domain of rifted margins. As more data becomes available our appreciation of the 3D and ultimately 4D geodynamic processes that influence the formation and present day structure of distal margins is evolving. Although all rifted margins are somewhat unique, similar genetic processes are often proposed despite the underlying interpretational uncertainties. These uncertainties can impact the resulting interpretations relating to the tectono-magmatic and crustal models. Therefore, despite many models the process often remains controversial and/or far for being well constrained.

This session would like to explore and discuss the observations and interpretations derived from geological and geophysical datasets across rifted margins and distal margins. Importantly, uncertainties should be addressed with respect to our current understanding of the genetic rift-domain evolution. Observations should focus on the evidences for processes that impact the final architecture, rock content and thermal imprint of conjugate margins. This relates to the observed style of extension and thinning (high vs low angle faulting and static vs dynamic interpretations and their evidence), vertical motions (e.g. uplift and subsidence), the isostatic impacts of the tectonic, magmatic and stratigraphic history relating to the genetic-rift domains.
