Onshore-offshore relationships at rifted margins (co-organized)
Convener: Jean Braun  | Co-Convener: Mary Ford 

Major advances have been achieved through the separate study of onshore and offshore sectors of passive margins. Recently, new insights have been achieved by linking onshore and offshore records of uplift/subsidence and mass transfer. The origin of the large relief characterizing the onshore part of margins such as Africa, Brazil, SE Australia has been re-examined,in terms of dynamic topography or other driving mechanisms capable of generating uplift and subsidence, as well as the coupling between surface processes, climate and tectonics. At the same time, detailed characterization of the sediment record in offshore basins has provided new insight on landforming events and how they may relate to mantle dynamics, lithospheric processes or climate variability. This session will focus on studies combining new onshore/offshore data and modelling to provide insight into the interactions at different spatial and temporal scales between surface processes, tectonics and climate during margin evolution.
