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]

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]

Paleogeography and the Northern Hemisphere Oceanic Gateways

Paleogeography and the Northern Hemisphere Oceanic Gateways

Eivind Straume a Postdoctoral fellow at the Department of Geological Sciences within the Jackson School of Geosciences explores how the opening and closing ocean gateways have influenced the Earth’s climate in the past.   Changes in Earth’s geography due to tectonic plate motions and mantle convection influence climate evolution on geological timescales. Over millions of years, continen ...[Read More]
