Plate tectonics is a key geological process on Earth, shaping its surface, and making it unique among the planets in the Solar System. Yet, how plate tectonics emerged and which factors controlled its evolution remain controversial. The recently published paper in Nature by Sobolev and Brown suggests new ideas to solve this problem…. What makes plate tectonics possible on contemporary Earth? It is ...[Read More]

The past is the key

Editorial Team 2 May 29, 2019

“The present is the key to the past” is a oft-used phrase in the context of understanding our planet’s complex evolution. But this perspective can also be flipped, reflected, and reframed. In this Geodynamics 101 post, Lorenzo Colli, Research Assistant Professor at the University of Houston, USA, showcases some of the recent advances in modelling mantle convection. Mantl ...[Read More]

Thoughts on geological modelling: an analogue perspective

In geodynamics we study the dynamics of the Earth (and other planets). We ground our studies in as much data as possible, however we are constrained by the fact that pretty much all direct information we can collect from the interior of the Earth only shows its present-day state. The surface rock record gives us a glimpse into the past dynamics and evolution of our planet, but this record gets spa ...[Read More]

We’ve all been there – you’re reading through a great new paper, keen to get to the Data Availability only to find nothing listed, or the uninspiring “data provided on request”. This week Krister Karlsen, PhD student from the Centre for Earth Evolution and Dynamics (CEED), University of Oslo shares some context and tips for increasing the reproducibility of you ...[Read More]
