The evolution of the North and South Atlantic is controlled by pre-existing tectonic features, mantle processes, and crustal response. The passive continental margins represent long-term and large-scale geo-archives of Earth processes related to mantle dynamics, the break-up of continents, the creation of sedimentary basins, long-term landscape evolution, changes in ocean circulation patterns and their effect on climate. Passive margins are also of paramount economic importance in terms of hydrocarbon resources. For this interdisciplinary session we seek contributions from natural case studies and from geodynamic or geomaterials modeling, which address the interplay of deep mantle - lithosphere - basin - surface â climate and erosion processes in passive margin systems and adjacent continents. We will greatly appreciate all thermochronological studies that contribute to the onshore â offshore feed-back processes. Furthermore, studies related to the contribution of magmatic activities in passive margins and adjacent continents since break-up are of major interest. The emphasis should be on the North and South Atlantic system and adjacent continents but exemplary case studies from other margin settings are also welcome. This session will try to tackle the complex interacting feedback cycles involving thermal and mechanical forces that acted over the ca. 200 million years since the beginning of breakup. We encourage scientist who deal with the long-term evolution of fracture zones at passive continental margins and adjacent continents to present their data as well.
