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]

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]

Repurposing a research tectonic modeling code as a community service: The case of DES3D
Three-dimensional model for core complex formation created with DES3D by Eunseo and his research group. Accelerated on NVidia V100 graphics card.

This week, Dr. Eunseo Choi, a professor at the Center for Earthquake Research and Information, the University of Memphis, talks about tectonic modelling using DES3D. *Spoiler alert* read till the end for an exciting opportunity to work on it The advent of the open-source movement and the free public software repositories such as GitHub have drastically improved the way research codes are maintaine ...[Read More]

Accretionary prisms are wedge-shaped bodies of crustal rocks that are commonly known to have formed by accommodating the component of convergence along subduction margins. These prisms, primarily wedge shaped with lateral variations in topographic height from hinterland to foreland are commonly characterised by a gentle and uniform slope towards the frontal margin (for instance, the Himalayan fold ...[Read More]
