Theme 7: Sedimentary systems

(Rüdiger Henrich, Hilmar von Eynatten, Maria Mutti, Harald Stollhofen)

Session 7.1: Young sedimentologists

Ulrich Heimhofer (University of Hannover), Michaela Spiske (University of Trier)

The organizers encourage submission of abstracts in all fields of sedimentology and sedimentary geology. The session aims at bringing together young researchers from various disciplines of sedimentary research in order to stimulate and promote discussion and exchange among the next generation of sedimentologists. The “Young Sedimentologists” session invites young scientists to present their completed or ongoing research work, i.e. results of their M.Sc. or PhD thesis. The session is sponsored by the SEPM-Central European Section and continues the tradition of the SEDIMENT meetings. Both poster presentations and oral talks are welcome. Oral presentations can be held either in German or in English. The most innovative and inspiring oral contribution will be awarded with the “Young Sedimentologists” presentation award in form of a book price sponsored by Springer.


Session 7.2: Chemostratigraphic and biotic events in Earth history

Christoph Korte (FU Berlin), Clemens V. Ullmann (University of Exeter, UK)

Sedimentary rock successions have been recording evidence for past environmental and biotic changes since billions of years. Information about these changes and the biological and a-biological revolutions shaping the Earth System is contained within sediment strata. A multitude of disciplines contributes to better understanding these past changes, including Sedimentology, Palaeontology, and Geochemistry.
This session invites contributions advancing and consolidating the knowledge about past environmental change, both rapid and gradual, by way of sedimentological, palaeontological, geochemical and numerical techniques.


Session 7.3: Epicontinental basins - sedimentary facies, land-sea transition and provenance

Matthias Hinderer (University of Darmstadt), Hilmar von Eynatten (University of Göttingen)

Remains of Phanerozoic epicontinental basins are spread over large parts of Europe. They record cycles of dissipated rifting and thinning of continental crust, and show long-lasting and slow rates of subsidence. Close to sea level they are highly sensitive to transgressions/regressions and show a pronounced cyclic sedimentary architecture. There sedimentary infill is dominated by clastic sediments, which is generally thought to derive from the surrounding basement realms, and mostly represent fluvial, eolian and shallow marine depositional environments. Marine episodes are characterized by weakly inclined carbonate ramps, evaporate formation and repeated low-oxygen stagnant conditions. The combination of producing, storing and sealing units provides good potential for oil and gas reservoirs. Late Cretaceous to Cenozoic uplift and salt tectonics inverted many of these basins in Central Europa.


Session 7.4: Carbonate mounds through time and space: from organisms to giant sedimentary structures

Dierk Hebbeln (MARUM, Bremen), Christian Dullo (GEOMAR, Kiel), André Freiwald (Senckenberg am Meer, Wilhelmshaven), Elias Samankassou (University of Geneva, CH)

Carbonate mounds in their widest sense are important and ubiquitous components of the sedimentary rock record throughout the Phanerozoic. Most have been formed by a variety of framework-building organisms such as corals, crinoids and bryozoans whose fossil remains commonly represent important components in these mounds. The processes of their formation and the environmental setting favoring it are still a matter of debate, basically because for long time it was assumed that hardly any true modern analogues to the widespread fossil carbonate mounds exist. However, the last two decades witnessed the discovery of thousands of modern carbonate mounds all along the margins of the Atlantic Ocean (and beyond) which mainly rely on cold-water corals as framework-builders. In size, shape and sedimentary structure these modern mounds bear many similarities to fossil carbonate mounds and, thus, might contribute as a true modern analogue to our overall understanding of carbonate mound formation. Here, we invite contributions dealing with fossil as well as modern carbonate mounds to trigger the dialogue between the communities focusing so far solely on the fossil or the modern carbonate mounds.


Session 7.5: From source to sink: Environmental signal propagation into the stratigraphic record

Hella Wittmann-Oelze (GFZ Potsdam), Anne Bernhardt (FU Berlin)

The depositional record represents a major archive of past terrestrial conditions and mountain erosion, but its interpretation may be hampered by the routing of sediment through lowlands and by autogenic processes in the sedimentary sink. To be able to interpret sedimentary archives with respect to past terrestrial conditions, an enhanced understanding of signal propagation through a sediment-routing system over different time scales and its manifestation in the sedimentary archive is necessary. Only if we understand source-to-sink sediment transport and environmental signal propagation over different time scales, we can understand how tectonics, climate, and human impact shape our landscape.
We therefore welcome studies on the generation of environmental signals in the erosional zone/ the mountainous source of the sediment-routing system that focus on surface interactions of climate, tectonics, and erosion. Moreover, we invite studies exploring sedimentary signal propagation through the (fluvial) transfer zone and studies from the depositional side investigating the evolution, architecture, and stratigraphy of sedimentary archives. We specifically encourage contributions focusing on the temporal evolution of surface processes using integrated approaches capable of tracing signals from the source to the sink.
Such studies could be performed in natural laboratories in a wide range of tectonic settings using various methodologies, from field observations or modeling. We encourage studies from the fields of geochronology, geomorphology, erosion and sedimentation dynamics, cosmogenic nuclides, sedimentology, structural analyses, geophysical imagery, and seismology.
