Rayleigh-Taylor instability in geodynamics

Rayleigh-Taylor instability in geodynamics

Flow against gravity is a common feature in the geodynamic phenomenon. In this week’s Geodynamics 101, Dip Ghosh from Jadavpur University Geodynamics Lab will explain the fundamentals of Rayleigh-Taylor instability: A key to understanding the anti-gravity flow. It has long been realized that most of the geodynamic processes can be described in terms of slow viscous flow. Thus, like many othe ...[Read More]

The Sassy Scientist – Sterling Subduction

The Sassy Scientist – Sterling Subduction

Fausto is very much preoccupied with subduction zones. The omphalos of his working life, or better yet, his paltry existence, he lacklusterly focuses on a single subduction zone. A proclivity for narrow-mindedness, surely. Yet there are ever so many to rejoice in. He thus warbles: What is your favourite subduction zone? Dear Fausto, I can only think of that one little special place deserving the p ...[Read More]

Rift linkage and rotating microplates

Rift linkage and rotating microplates

2020 left your head spinning? This week Derek Neuharth from GFZ Potsdam introduces us to the spinning microplates that can be found in extensional plate boundaries such as the East African Rift System and the East Pacific Rise. Divergent plate boundaries Microplates are enigmatic features that form in the boundaries between tectonic plates. Generally, plate boundary dynamics are divided into three ...[Read More]

2021: 100th year of the craton concept and beyond

2021: 100th year of the craton concept and beyond

One hundred years back, Leopold Kober first introduced the term “Kratogen”. With time, the concept of kratogen has evolved, and they are now known as cratons. In this week’s news and views, Jyotirmoy (@GeophyJo), a PhD student from the Indian Institute of Science revisits the history of craton science: how the craton concept has evolved and what are the modern problems related to them.   &nbs ...[Read More]
