SAMPLE Session at GeoFrankfurt 2014

At this year's GeoFrankfurt a SAMPLE session entitled "The first step of the Wilson Cycle: Rifting to post-breakup processes of passive continental margins" will be convened by Ulrich A. Glasmacher, Hans-Peter Bunge, Georg Rümpker, Friederike Bauer, Sebastian Kollenz, and Jan Behrmann.

SAMPLE Session at GeoFrankfurt 2014

Where: Goethe Universität Frankfurt a. M.

When: Tuesday, 23.09.2014, beginning at 10:30 a.m.

Session description:

The Wilson Cycle describes the evolution of our planet by movement of lithospheric plates. Its first step guides the evolution from a single plate into separated plates by breakup through rifting processes. While the geometry, lithology and physical properties of the initial lithospheric plate are a precursor to the evolution of passive margins, this assumption has to consider possible modifications caused by processes during the rifting and post-rifting stage. Furthermore, the long-term behavior of the lithospheric plates can be monitored by the topographic evolution since the initial breakup, if climate variability is adequately considered. A great opportunity exists to decipher breakup processes of the Wilson Cycle, because passive continental margins represent long-term and large-scale geo-archives of Earth processes related to mantle and lithospheric dynamics, the breakup of continents, the creation and post-break up evolution 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 highly interdisciplinary session we seek contributions from natural case studies and from geodynamic or geomaterials analog and numerical modeling, which address the interplay of deep mantle – lithosphere – basin – surface – climate and erosion processes in passive margin systems and adjacent continents. We welcome all studies that contribute to elucidating the onshore - offshore feed-back processes and the links between on- and offshore tectonics. Studies related to the role of magmatic activities in passive margins and adjacent continents since break-up are also of major interest. Therefore, the session invites a wide range of contributions that present cutting edge research results and theories related to pre-breakup, lithospheric, structural and physical properties, breakup processes, post-breakup modifications and recent structure and physical properties of passive continental margins and adjacent continents.
