About me: I am interested in geodynamics, plate tectonics, natural hazards, georesources and the carbon cycle - using numerical models like the one below. 🧪⚒️

I co-organize and post about the monthly online #RiftAndRiftedMarginsSeminar. More infos here: tinyurl.com/RiftAndRiftedMarginsSeminar

Our new study on @egu.eu SE combines automatic fault mapping, geodesy and rock dating to reconstruct the tectonic and magmatic evolution of the Afar rift during the last 4.5 Myrs. @sasbrune.bsky.social @sorcerinsar.bsky.social @derekkeir.bsky.social @gimmi-p.bsky.social @earth-science.bsky.social

Cross-scale strain analysis in the Afar rift (East Africa) from automatic fault mapping and geodesy

Abstract. The formation of continental rift systems is characterised by the interplay of magmatic and tectonic processes. Their evolution involves a wide range of timescales, from centennial scales of...

Phase transitions control plume layering during Earth’s secular cooling

Earth’s structure and dynamics have evolved quite a lot since its formation, and so has mantle dynamics and convection patterns changed along with it. It turns out that phase transition in certain man...
