Rifts provide a unique window into the geodynamic system of our planet and the processes that shape the surface of the Earth. This project aims at a thorough understanding of continental rift dynamics and rifted margin formation by means of a comprehensive multi-scale numerical modelling design.

News and Highlights

 August 2018:

      We welcome new PhD student Derek Neuharth. Derek’s research topic is “Geodynamics of Continental Rifted Margin Formation – Numerical Modelling of Rift Processes from Localisation to Break-up”.

      Congratulations to Ethiopian colleague Ameha Muluneh who gained a TWAS-DFG fellowship with which he will visit us from January to April 2019. Ameha will work on "Rheology of Continental Rifting: A Multi-observational approach integrating geophysical, geological and geodynamic techniques" with a special focus on the Ethiopian Rift.

July 2018:

      Two new article preprints are online:

      (1) Max's paper on strain localisation reproducing rheological experiments and beyond (Link to EarthArXiv);

      (2) Sascha's analysis of rift obliquity since 230 Ma (Link to Solid Earth Discussion).

June 2018:

      We welcome new team member Tim Hake for his internship on automated fault analysis in numerical models.

May 2018:

      Our block course on geodynamic modelling at the University of Potsdam was a great success. We thank the 21 participants for their team spirit and enthusiasm.

April 2018:

      We welcome new team member Esther Heckenbach for her internship on transient vs. steady state behaviour in continental rifts.
