Equilibrium Crustal Thickness and Dynamics of Earth’s Lithosphere: The Answer is 42.

Equilibrium Crustal Thickness and Dynamics of Earth’s Lithosphere: The Answer is 42.

“The Hitchhiker’s Guide to the Galaxy” had the answer; we think we have the right question. This week, Ajay Kumar from IISER Pune, India, will take us on a journey to the depths of the Earth’s lithosphere – a world as mysterious as the farthest reaches of the Universe. We will see what the thickness of the Earth’s crust can tell us about the balance between the ...[Read More]

How we made QUARTETnary – the card game about the geological time scale

How we made QUARTETnary – the card game about the geological time scale

QUARTETnary is an educational card game about the geological time scale. Consisting of 60 beautifully illustrated cards, QUARTETnary explores the events in Earth’s history: from dinosaurs to humans and from the formation of the Alps to the formation of the Himalayas. It was designed by Iris van Zelst (me! Your fabulous former Editor-in-Chief), and illustrated by Lucia Perez-Diaz (also a former edi ...[Read More]

Regional viscosity variations in Earth’s mantle

Regional viscosity variations in Earth’s mantle

For understanding the dynamics and evolution of the Earth’s mantle, knowledge of mantle’s viscosity structure is very important. In this week’s blog, Kenneth Gourley from University of Arizona discusses the variation of viscosity structure in Earth’s mantle in regional scale.   In order to understand the dynamics and evolution of the Earth’s mantle, geodynamicists model mantle fl ...[Read More]

H2 production associated with mantle wedge hydration in subduction zones

H2 production associated with mantle wedge hydration in subduction zones

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]
