Magma-Assisted Flexure in Hawaiian Lithosphere?

Magma-Assisted Flexure in Hawaiian Lithosphere?

This week Daniel Douglas, who is now a PhD student at New Mexico Tech, discusses his master thesis research while at the university of Hawaii. He investigated the role of magma in the flexure of the Hawaiian lithosphere. When a topographic load is applied to the lithosphere, the lithosphere accommodates the load by flexing. The observed flexure can be measured through seismic methods, gravity anom ...[Read More]

To boldly go… deep sea exploring to study Earth’s interior

To boldly go… deep sea exploring to study Earth’s interior

As geodynamicists, we are sometimes oblivious on how we get the geophysical constraints in our numerical models. This week Molly Anderson, a PhD student at the University of Florida, takes us on a exciting dive to study the geochemical signatures of the East Pacific Ocean seafloor! People are often surprised to hear that the seafloor is covered with volcanoes, let alone that the most extensive cha ...[Read More]

The Deccan Chronicle: Plume or no-Plume? Perspective from a Deccan dyke swarm

The Deccan Chronicle: Plume or no-Plume? Perspective from a Deccan dyke swarm

Deccan volcanism is one of the landmark events in India’s geodynamical history. Yet, its origin is still under debate regarding its association with the Réunion plume.  In this week’s news and views, Ayanangshu Das, a PhD student at the Indian Institute of Science Education and Research (IISER), Bhopal, explains their recent study to understand the emplacement mechanism by observing the magm ...[Read More]

Thermodynamics and Geodynamics: The perfect couple? Part II

till heat death do us part?

In January of this year, Bob Myhill wrote about the coupling of geodynamics and thermodynamics, and why this coupling is so valuable. This blog post, Juliane Dannberg follows up on this topic, looking at it from the geodynamics perspective. In other words, discussing the question: Where does it make a difference in geodynamic models if we include realistic thermodynamic models or not? In geodynami ...[Read More]
