Jeroen takes on the role for 2021-2023, from Paul Tackley (ETH Zürich). Jeroen is a Professor within the Department of Geosciences, including the Geodynamics, Geophysics, and The Solid Earth research groups. He is originally from the Netherlands, having studie ...[Read More]

Can plume-lithosphere interaction initiate a modern subduction zone?

Editorial team 1 April 15, 2020

This week in News & Views, dr. Marzieh Baes from GFZ Potsdam introduces us to the mechanisms behind subduction initiation. Moreover, she discusses the different types of subduction initiation in reaction to plume-lithosphere interaction that she observed in her recent 3-d numerical modelling study. Possible scenarios of subduction initiation According to plate tectonics, oceanic plates are for ...[Read More]

Enigmas at depth

Editorial team 1 November 13, 2019

The Geodynamics 101 series serves to showcase the diversity of research topics and/or methods in the geodynamics community in an understandable manner. In this week’s Geodynamics 101 post, Marcel Thielmann, Senior Researcher at the University of Bayreuth, discusses the possible mechanisms behind the ductile deformation at great depths that causes deep earthquakes. Earthquakes are one of the expre ...[Read More]

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]
