Applying for a PhD in Geoscience: To do or not to do

Applying for a PhD in Geoscience: To do or not to do

Fresh out of your bachelor’s degree, or more commonly these days, your master’s degree, it can be tempting to pursue your PhD as quickly as possible. While there are compelling reasons to dive straight in, rushing into a PhD might not be your best choice.   To be or not to be a researcher? Before you start firing off applications, take a step back. Forget any expectations you had ...[Read More]

Phase transitions control plume layering during Earth’s secular cooling

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 mantle minerals can be an important driver of this change. Today, Ranpeng Li from GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany explains how coupling geodynamic models with thermodynami ...[Read More]

One Ring to Rule Them All: The Geology of Middle-earth

One Ring to Rule Them All: The Geology of Middle-earth

Few fantasy worlds have captured the imagination of readers and viewers like J.R.R. Tolkien’s Middle-earth. Whether you first encountered it through The Lord of the Rings or the sweeping visuals of Peter Jackson’s films, chances are your eyes lingered on the same thing geologists can’t help obsessing over: the mountains. Towering, treacherous, mysterious — the Misty Mountains, the White Mountains, ...[Read More]

Resisting self-guilt as a PhD student

Resisting self-guilt as a PhD student

Self-guilt is a common feeling among PhD students. It often leads us to devalue ourselves more harshly than is fair and to form unrealistic expectations. It is important to understand how it shows up in our daily work, what fuels it, and how we can resist it — because over time, it can quietly undermine both our well-being and our work. The ideas below are the results of group discussions that hav ...[Read More]

Reflecting on the 2025 Gordon Research Seminar (GRS) – Interior of the Earth

Reflecting on the 2025 Gordon Research Seminar (GRS) – Interior of the Earth

This week in News & Views, Heidi Krauss, a PhD student at Michigan State University, shares her experience co-chairing the 2025 Interior of the Earth Gordon Research Seminar, held at Mount Holyoke College in South Hadley, Massachusetts. Earlier this year, I had the opportunity to help co-chair the Gordon Research Seminar (GRS) on the Interior of the Earth, held just before the main Gordon Rese ...[Read More]

Simulating the Deep Earth with MAGEMin: A Toolkit for Thermodynamic Modeling in Geodynamics

Simulating the Deep Earth with MAGEMin: A Toolkit for Thermodynamic Modeling in Geodynamics

Understanding how rocks melt, deform, and evolve within Earth’s interior is a central challenge in geoscience. These processes span a wide range of spatial and temporal scales and are governed by complex interactions between temperature, pressure, composition, and phase stability. Capturing this complexity in numerical models requires integrating mineral thermodynamics directly into geodynamic mod ...[Read More]

Unraveling volcanic patterns between adjacent rift zones

Unraveling volcanic patterns between adjacent rift zones

Continental rifts are a prime example of how the forces at work beneath our feet are constantly shaping our world, and often host volcanic activity. The patterns and distribution of volcanism in rift settings, however, is far from intuitive. The picture gets even more complicated if we look between the segments that often make up a rift. This week, Valentina Armeni from the University of Potsdam, ...[Read More]

Don’t Stop Me Now: A Fracture Mechanics Perspective on Earthquake Nucleation

Schematic for a possible earthquake nucleation scenario. Inset figure adapted after Lebihain et al. (2021) and McLaskey (2019).

How do earthquakes start? Earthquakes occur when a block of rock rapidly slides past another along an interface or a discontinuity in the medium and release energy in the form of seismic waves. Turns out, the surface of the earth is riddled with a lot of these discontinuities, which we call “faults”. If we plot the locations of earthquakes on a world map (Figure 1a), we will see that they highligh ...[Read More]

Happy 8th blog birthday and introducing the new blog team!

Hello there! It’s Constanza and Michaël your GD editors-in-chief once again. End of June marks the 8th anniversary of the blog, so happy birthday to the blog! It’s been some pretty busy weeks of preparation behind the scenes after the EGU General Assembly to bring together the new blog team for the year 2025-2026. We are a team of early career scientists who are very enthusiastic about ...[Read More]

What drives the extensional deformation in the central Apennines (Italy)?

What drives the extensional deformation in the central Apennines (Italy)?

The central Mediterranean is a geodynamically complex region shaped by the interaction of multiple active subduction zones. In Italy, the central Apennines display a distinctive pattern of surface deformation that is proposed to be linked to a slab break-off beneath the area. In this week’s blog post, Maaike, a PhD student at ISTerre in Grenoble, France, explores the key processes driving surface ...[Read More]
