Can plume-lithosphere interaction initiate a modern subduction zone?

Plume-induced subduction inititation?

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

Enigmas at depth

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]

What controlled the evolution of Plate Tectonics on Earth?

Great Unconformity - Immensity River, Grand Canyon

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

The past is the key

“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]
