T042:
The evolution and architecture of rifts and rifted passive margins: from mantle dynamics to surface processes





Session ID#: 23397

Session Description:
The formation of rifted continental margins by extension of continental lithosphere leading to seafloor spreading is a complex and still poorly understood component of the plate tectonic cycle. New observations and modelling allow us to investigate the underlying processes. Key questions to be resolved include 1) factors controlling geometry and crustal architecture or rifted margins, 2) controls on the structural style of rift and passive margin formation 3) factors controlling the 3-dimensional geometry of rifts and passive margins, 4) processes responsible for anomalous vertical motions during basin evolution, 5) fundamental controls on the magmatic or a-magmatic nature of rifts and passive margins, 6) interaction between surface processes, tectonics, and climate during rift-passive margin evolution. We encourage abstracts that offer new insights into crustal and lithospheric architecture and processes underlying rift-passive margin formation as well as smaller scale studies of individual sedimentary basins, using constraints from observations and modelling.
