From Rocks to Models: Reconciling Field Geology with Geodynamic Simulations

From Rocks to Models: Reconciling Field Geology with Geodynamic Simulations

When reading a scientific paper or a text explaining the physical workings of the Earth, one of the most striking aspects is the methodological approach—sometimes involving numerical models, other times fieldwork and/or rock geochemistry. This diversity of approaches can initially cause some discomfort, a feeling that things are like square pegs in round holes. How can a computer model dialogue wi ...[Read More]

How do rocks fail and flow: A beginners guide to rock rheology

How do rocks fail and flow: A beginners guide to rock rheology

The field of rock rheology may seem a bit ‘odd’ at first glance to those geoscientists who are vaguely familiarized with the topic of geodynamics. Often, rocks are considered massive and competent geomaterials that display a sudden (and sometimes violent) brittle failure (earthquake alert!). However, when considering the high temperatures and large timescale characteristics of most geo ...[Read More]

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]
