The Geodynamics Awakens: Star Wars Planets and Earth’s Geological History

The Geodynamics Awakens: Star Wars Planets and Earth’s Geological History

Star Wars is one of the most influential science-fiction worlds created in our time. The central theme revolves around the struggle between the tyrannical Galactic Empire and the rebels trying to bring it down. Star Wars has many reasons to pull you in: iconic lightsaber duels, technological advancements such as hyperspace travel, and perhaps most importantly for a geologist: a remarkable number o ...[Read More]

The pulsed rise of the Nahuelbuta Range: How glaciers indirectly built a mountain in Patagonia

The pulsed rise of the Nahuelbuta Range: How glaciers indirectly built a mountain in Patagonia

Forearc ranges are a striking example of how tectonic processes shape our planet. The Nahuelbuta Range in southern Chile is one of such settings. This week, Ambrosio Vega-Ruiz from the GFZ Helmholtz Centre for Geosciences, Germany, is telling us the story of this remarkable range, exploring how climate feedback can influence tectonic uplift across coastal forearcs. Tectonic uplift before tectonic ...[Read More]

The truth about The Odyssey: Geodynamics, lies, cries and the hunt for Ithaca

The truth about The Odyssey: Geodynamics, lies, cries and the hunt for Ithaca

If you have ever tried to draw a geological cross-section under a fantasy map, Homer is surprisingly cooperative (and if you remember my Middle-earth geology post, you already know I live for this). The Odyssey is full of real places and real people—Troy, Mycenae, Sparta—stitched together with storms, monsters and divine interventions that would make any structural geologist reach for a stress ten ...[Read More]

Destruction of North China Craton: through the chronotunnel of time

Destruction of North China Craton: through the chronotunnel of time

The Asian continent has fascinated the world for at least 3,000 years with its music, food, and discoveries, as well as its breathtaking landscapes. Most of these incredible landscapes are formed by mountains that can be considered geologically “recent” (such as the Cenozoic formation of the Himalayas). However, there are also ancient terrains, pre-dating the Mesozoic, that pose intrig ...[Read More]

At the Mountains of Madness: Lovecraft Applied for Geology (and Failed)

At the Mountains of Madness: Lovecraft Applied for Geology (and Failed)

“I am forced into speech because men of science have refused to follow my advice without knowing why. It is altogether against my will that I tell my reasons for opposing this contemplated invasion of the antarctic—with its vast fossil-hunt and its wholesale boring and melting of the ancient ice-cap —and I am the more reluctant because my warning may be in vain.” The opening lines from At the Moun ...[Read More]

Destruction of the North China Craton and its global impact

Destruction of the North China Craton and its global impact

Cratons are forever, until they are not. These long-lived portions of lithosphere are known for being remarkably stable. However, if the conditions are right, even cratons can be ripped apart by geological forces, with far-reaching impacts on Earth’s systems. This week, Jyotirmoy Paul from the University of Oslo, Norway will tell us the downfall of the North China Craton, using numerical sim ...[Read More]

From Mountains to Oceans: How the memory of ancient orogens guides the rupture of continents

Picture showing an orogen that transform in a rift

In this new blog, Dr. Kai Li (GFZ Potsdam) talk about his PhD work, where he used accordion numerical models to explore the tectonic history of the South China Sea. His PhD research focuses on the impact of orogenic inheritance on rifts and rifted margins, employing advanced geodynamic modeling techniques. Have you ever tried to fit the west coast of Africa and the east coast of South America toge ...[Read More]

Kamchatka Megathrust Earthquake: What lies in the Pacific Ring of Fire

Kamchatka Megathrust Earthquake: What lies in the Pacific Ring of Fire

From the very early years on this Planet, earthquakes have always captivated people’s attention. The feeling of admiration and fear always lies within us, especially drawing on the most recent megathrust earthquake that hit the south coast of Kamchatka’s Peninsula, in Russia, twice this year. Therefore, in this week’s blog, we aim to explore how this phenomenon evolved and why this specific region ...[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]

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]
