Rotations in extensional tectonic settings: from plate kinematics to rift evolution and propagation
Convener: Nicolas Molnar  | Co-Conveners: Frank Zwaan , Guido Schreurs 

Tectonic settings where the relative displacement between lithospheric plates has a rotational component are very common in the geological record: all major continental breakup events have involved rotation between plates and the associated propagation of rifts and oceanic basins.

It is generally agreed that spatial changes in plate kinematics exert a first-order control on the evolution of deformation and strain partitioning along divergent margins and extensional basins, but how their structural features develop in response to such rotational motions remains poorly understood.

This session aims to bring together new research across multiple disciplines that focus on rotations in extensional settings; we encourage studies ranging from geophysics, paleomagnetism, geodesy and geochronology to tectonics, structural geology, analogue and numerical modelling in order to promote cross-disciplinary discussions that lead to new insights on this exciting topic.
