Conveners invite contributions that aim towards integrating sedimentology, paleontology, structural geology and/or modelling techniques. If this is of interest to you, please submit an abstract (→ https://www.geosaxonia2024.de/call-for-abstracts.html) until May 6th and do not hesitate to ask if you have any questions.

Session 8G description: Sedimentary basins are critical archives for understanding the Earth’s surface response to environmental disturbances, including climate changes, and serve as the primary field for reconstructing Earth’s evolution throughout geological time. Moreover, they offer insights into the mechanisms controlling natural hazards, pollutant transport across the land, the genesis and preservation of natural resources, as well as potential gas/waste storage sites and geothermal reservoirs. Therefore, understanding the processes operating in sedimentary systems is pivotal to effectively address societal challenges such as global warming, natural resources management, energy transition and security by providing a scientific basis for sustainable development strategies.
Here, we invite contributions that utilize multi-disciplinary approaches to investigate and characterize sedimentary successions aiming to retrieve insights about (1) the evolution of depositional environments and the impacts of environmental perturbations – such as changes in climates or tectonic settings – on their development across various temporal and spatial scales; (2) the drivers, magnitudes and frequencies of natural hazards such as mass wasting processes; (3) the quantification of the rates of erosion, sediment transport and deposition. Contributions are welcome from field observations, subsurface studies, proxy reconstructions, as well as physical and numerical modelling that take a holistic approach to understanding the evolution of marine and terrestrial sedimentary systems as recorders of changes in climate, ecosystems and/or tectonics/geodynamics.

PhD position in understanding the evolution of the intramountain basins (Dinarides, SE Europe)

Deadline - 5th of July 2023

The General Geology research group at the Karlsruhe Institute of Technology (KIT), Germany, announces 1 PhD position associated with a new Weave (DFG-FWF)-funded project (“Did the Dinaric Alps force an arid climate and speciation during Miocene Climatic Optimum?”). It is a collaborative effort of the Karlsruhe Institute of Technology and Natural History Museum in Vienna that aims to derive a timeline of the evolution of the intramountain basins across the Dinarides, which is pivotal for understanding the mechanisms controlling the mountain growth and its interactions with the climate and fauna. Candidates with interests in sedimentary basin dynamics, stratigraphy, radiometric dating, tectonics and paleoclimate should apply.

The appointment is for 36 months and salaries are at the German TV-E13 level (75%).

Responsibilities: The candidate will 1) compile geological data in order to determine local and regional stratigraphic sequences in intramountain basins across the Dinarides; 2) detailed sedimentological mapping of the boreholes and outcrops of selected basins; 3) do U-Pb dating on the zircons from ash layers and lacustrine carbonates, and 4) collaborate with researchers from Natural History Museum Vienna and collaborators from the University of Belgrade and the University of Zagreb, and industry partners to address the project’s aims.

Foreland basins: Decoding feedbacks between tectonics, climate, and biota

Nevena Andrić-Tomašević, from our research group, Laura Stutenbecker, Anne Bernhardt, and Davit Vasilyan are hosting a session at GeoBerlin2023 (3-7. September): "Foreland basins: Decoding feedbacks between tectonics, climate, and biota".

Conveners invite contributions that aim towards integrating sedimentology, paleontology, structural geology and/or modelling techniques. If this is of interest to you, please submit an abstract until May 3rd and do not hesitate to ask if you have any questions.

Session Description: Foreland basins develop along both fronts of a growing mountain range, making them excellent recorders of crustal- to lithosphericscale deformation, erosion, deposition, topographic changes, regional and global climate changes, and biota evolution and organism dispersal. Therefore, foreland basins offer unique opportunities to study the feedback mechanisms between tectonics, climate, surface processes, and biota at the Earth’s surface. We encourage contributions using multi-disciplinary approaches focusing on decoding foreland basin sedimentary successions and basin dynamics for retrieving information (1) about orogen and basin dynamics, and (2) about interactions between tectonics, climate, surface processes, and biota (fauna and flora). Contributions are welcome from field observations, subsurface studies, and physical and numerical modeling studies across all temporal and spatial scales. We look forward to receiving contributions focusing on forelands associated with both collisional and accretional orogens such as the Andes, North American Cordillera, Alps, Dinarides, Apennines, Carpathians, Caucasus, and forelands in Tethyan, Paratethys, and other realms worldwide.

How does slab tearing evolve
How does slab tearing evolve?

Slab tearing refers to the gradual propagation of the break-off of a subducting plate. As observed in numerous modern and ancient convergent tectonic settings, the growth of the tear “window” in the downgoing plate has strongly influenced various geologic and geodynamic processes, such as depocenter migration of foreland basins, uplift rates in mountain ranges, earthquakes, volcanism, and flow patterns in the upper mantle. However, our understanding of the dynamics of slab break-off and tearing, especially in non-collisional environments, is still limited.

March, Wednesday 29th was the #blogday for the Geodynamics Division. In this week's #EGUblog, Nevena Andrić-Tomašević, Tenure-track Professor at the Institute of Applied Geosciences, Karlsruhe Institute of Technology (KIT), and Alexander Koptev, a postdoctoral researcher at the German Research Centre for Geosciences (GFZ Potsdam), report on their recent work on slab tearing in the context of oblique oceanic subduction

Andrea Piccolo, Guest Postdoc from BGI, Univ. Bayreuth
Invited researcher - Dr. Andrea Piccolon (BGI, Univ. Bayreuth)

Andrea Piccolo visited our research group between 20th and 29th of March for a collaborative research work on the effects of slab break-off on the evolution of Molasse basin (or North Alpine foreland basin).

He is one of the active developers of the thermo-mechanical code LaMEM which we are using for the Molasse project. He has developed 2D and 3D numerical models in LaMEM to investigate the topographic response of slab break-off in the foreland basin. His model results are being used as input parameters in commercial software Petrel to develop a stratigraphic forward model to assess whether evolution of Molasse basin is influenced by slab break-off process.

Apart from the Molasse project he is our active collaborator in other research projects involving thermo-mechanical code LaMEM.

36th IAS Conference
36th International Meeting of Sedimentology

We would like to draw your attention to our session Intramountain basins – recorders of tectonics, climate, and biota interactions during upcoming the 36th International Meeting of Sedimentology taking place in Dubrovnik (12th - 16th June 2023).

Session description: Intramountain basins are an integral part of the mountain ranges. Therefore, they are important recorders of deformation, erosion, syntectonic deposition, magmatic events, variations in biodiversity, and local and regional climatic evolution. Therefore, their sedimentary succession provides an insight into links, interactions, and feedback between tectonics, climate, and biota.

This session aims to assemble research efforts focusing on the dynamics and evolution of the intermountain basins at various temporal and spatial scales, and the “inversion” of their sedimentary record to reconstruct climatic, tectonic and/or biotic evolution/interaction. We invite contributions from the broad field of earth sciences based on field observations, and numerical and experimental work. Please, remember the deadline for abstract submissions is 15th February.

The session will be accompanied by the pre-conference field excursion (10.-12. of June) focusing on the intramountain basins of the Dinarides lake systems and the southern Pannonian basin environmental evolution (excursion A3, please see details https://www.iasdubrovnik2023.org/eng-excursions.php). The IAS offers travel grants for IAS student members (please see details https://www.sedimentologists.org/grants).
