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.
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).
We welcome new team member Tim Hake for his internship on automated fault analysis in numerical models.
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.
We welcome new team member Esther Heckenbach for her internship on transient vs. steady state behaviour in continental rifts.
Anne wins a poster price at the Dutch Earth Science Congress (https://nacgeo.nl) for her presentation of "3D Numerical Rift Modelling with Application to the East African Rift System". Congratulations!
