Subduction zones are dynamic regions where intense geological processes like earthquakes, volcanic eruptions, and the recycling of oceanic crust are constantly at play. A key factor that influences the behavior of these zones is *interface rheology*—the strength and viscosity of the boundary (the interface) between the subducting and overriding plates. Understanding this interface is crucial for i ...[Read More]

Dihydrogen (H2) is a promising source of energy that may allow reducing carbon emissions in industry and transportation. Artificial production methods have been explored, natural sources of H2 (also called white dihydrogen) offer a more eco-friendly and cost-effective production process. In this week’s blog post, Alexis Gauthier, a PhD student from ISTeP, France, is discussing the H2 production pr ...[Read More]

Multiengine-driving Tethyan evolution

Zhong-Hai Li and edited by Zhibin Lei January 17, 2024

The highest mountain range in the Alps in the Western Europe, the towering peaks of the Himalayas in Asia, and ~1/3 world crude oil production in the middle east – what brings these remarkable nature gift together? The answer is Tethyan orogenic belt, which spans across the entire Eurasian continent. This week, we are privileged to have Prof. Zhong-Hai Li from the University of Chinese Academy of ...[Read More]
