Seismic discontinuities necessitates mechanisms that would generate them and therefore, help us better understand the internal structure of the Earth. This week, Martina Monaco talks about the mysterious X-discontinuity — observed under several hotspots at upper mantle depths of ~ 290 km —and how it relates to the rising plumes. According to the Oxford Dictionary, …[Read More]
Did you know that there are big, blob-like anomalies in the deep mantle which are larger than a continent and rise up to hundreds of kilometers from the core-mantle boundary? Today’s post is all about those blobs and what we know and do not know about them. If you want to know more about why …[Read More]
Plate interface lubrication is essential for stabilization and continuation of subduction process for million of years. The magnitude of plate interface lubrication determines transfer of stress between two converging plates, topography of mountain belts, transportation of volatiles to the mantle, and return flow of high to ultra-high pressure rocks to the earth’s surface. In this …[Read More]
Have you ever wondered how Earth became habitable. In this week’s news and views, we have Fabio Capitanio, Associate Professor at Monash University sharing insights into the role Geodynamics in the evolution of Earth and life on it. Our planet has unique features which make it suitable for life. Understanding how the Earth became habitable is necessary to …[Read More]
While we have sent several rovers to Mars, drilling down even just to the mantle of our own planet is a challenge that we are yet to overcome. How is it then that we know all these things about our planet’s interior? It turns out, we do not need to be inside the Earth to …[Read More]
The EGU Geodynamics blog is 5 years old today! *throws confetti* Imagine being on the same contract in the same country for that long… Wow. Truly incredible. So let’s have a look at what we did over this past year of blogging. What did we do? Write and edit, mainly. I know – who’d’ve thought …[Read More]
The Geodynamics division at the European Geosciences Union is looking for two new Science Officers to join the EGU GD Programme Group. Come join us and help shape the future of EGU conferences! What is a Science Officer and what do they do? Science officers work together to design an exciting, diverse, broad, and inclusive …[Read More]
Plume craton interaction is a fascinating geological phenomenon. The Indian plate, which has experienced several plume eruptions underneath it, is one of the best locations to study the effect of plume craton interaction. In this week’s news and view, I will provide an overview of the controversy and hypotheses related to the plume craton interaction …[Read More]
The Geodynamics division of the European Geosciences Union is looking for a new Early Career Scientist representative (ECS Rep)! Our current ECS Rep (Anna Gülcher) will be stepping down at the EGU General Assembly 2022, which means that the amazing opportunity is open for you to take on this role! In this blog, Anna talks about …[Read More]
Science is all about discovering new things. But how do we make these discoveries, adding to the ever growing pantheon of knowledge? This week, we sit with one of our editors Antoniette Greta Grima, a Postdoctoral Fellow from the University of Texas at Austin, to understand what it takes to discover a new slab process. …[Read More]
