TS6.4

What controls lithosphere evolution during extension? The aim of this session is to investigate diverging systems over a wide range of spatial and temporal scales, and at all stages in the life cycle of divergent plate boundaries including continental rifting, mantle exhumation and seafloor spreading.
A special emphasis will be given to
(1) studies that couple lithospheric deformation models to plate kinematics, and that integrate possibly the role of serpentinisation and/or magmatism in the models.
(2) works that analyse subsidence and thermal effect of rifting and break-up.
(3) paleogeographic reconstructions revealing the influence of sedimentation and lithosphere structure evolution on biogeochemical cycles and oceanographic circulation.
(4) contributions that elucidate extensional modes through the interplay between tectonic structures, magmatism and the stratigraphic record using field, petrological and seismic data.
