LLSVPs: Mysteries in the Deep Mantle

LLSVPs: Mysteries in the Deep Mantle

Did you know that there are big, blob-like anomalies in the deep mantle which are larger than a continent and rise up to hundreds of kilometers from the core-mantle boundary? Today’s post is all about those blobs and what we know and do not know about them. If you want to know more about why these blobs are so interesting to study, check out this other cool blog post by Jamie Ward. If you look at ...[Read More]

Application of lubrication theory in understanding subduction interface dynamics

Application of lubrication theory in understanding subduction interface dynamics

Plate interface lubrication is essential for stabilization and continuation of subduction process for million of years. The magnitude of plate interface lubrication determines transfer of stress between two converging plates, topography of mountain belts, transportation of volatiles to the mantle, and return flow of high to ultra-high pressure rocks to the earth’s surface.  In this week’s blog, I ...[Read More]

Geodynamics: It’s in the air we breathe!

Have you ever wondered how Earth became habitable. In this week’s news and views, we have Fabio Capitanio, Associate Professor at Monash University sharing insights into the role Geodynamics in the evolution of Earth and life on it. Our planet has unique features which make it suitable for life. Understanding how the Earth became habitable is necessary to answer the most fundamental question ...[Read More]

Into the anisotropic Earth

Into the anisotropic Earth

While we have sent several rovers to Mars, drilling down even just to the mantle of our own planet is a challenge that we are yet to overcome. How is it then that we know all these things about our planet’s interior? It turns out, we do not need to be inside the Earth to know what is happening there. Observations from geophysics and geochemistry can inform us about the processes and the properties ...[Read More]
