Mathematics is certainly not every scientist’s cup of tea. Despite the latter, they are, for the most part, very important, since most problems, regardless of their complexity, start and end with a mathematical equation (or set of equations). In this week’s blog, Dimitrios Papadomarkakis (student at the National Technical University of Athens), discusses the subject of closed-form (analytical) sol ...[Read More]
The 4.5 billion years of geologic evolution has shaped the tectonic processes in Earth we see today. Over the span of time, Earth has changed from being a magma ocean to a tectonically active planet, by transitioning through different tectonic regimes. A silent witness of this journey have been cratons which have survived for billions of years. Therefore cratons preserve clues of past tectonic pr ...[Read More]
As geoscientists, we tend to see geology everywhere. Around Christmas, many people stare at decorated fir trees and twinkling lights; salt tectonicists stare at seismic lines and outcrops and see… trees as well. Tall stems, branching limbs, stacked “tiers” of material; a whole forest of geological Christmas trees hiding in the subsurface. In salt provinces around the world, from the Flinders Range ...[Read More]
Assume you are under stress. What do you do? Take a walk in the park, order your favorite takeout, have a breakdown, or internally slip along preferred slip systems and develop a fabric? The response will mostly depend on what kind of material you are, how much stress you are under, and what environmental conditions you are subjected to. For instance, someone might listen to classical music after ...[Read More]
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]
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]
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]
With the EGU General Assembly (GA) less than a month away, attendees should start planning their schedules to get the most out of the week. In today’s blog, Geodynamics (GD) Division Early Career Scientist (ECS) representative Garima Shukla highlights the GD Division’s networking events and provides an overview of key events at the GA. Networking Events: Geodynamics Division What: ECS ...[Read More]
Evaporitic rocks possess unique properties that enable them to form crucial structures for petroleum systems. Salt basins are globally distributed, particularly along the Atlantic margins. Their thermal and mechanical properties can influence the Earth’s crust, altering structural styles and basin architecture, with significant implications for hydrocarbon exploration and geodynamic processes. How ...[Read More]
Geodynamic modelling helps us understand Earth’s internal processes by providing a framework to test hypotheses. Analogue modelling uses physical models governed by the laws of nature, with resolution down to Planck’s length. In contrast, numerical modelling employs mathematical methods to approximate solutions to the physical laws governing Earth’s processes. Each modelling approach comes with it ...[Read More]
