X and mantle plumes: the deep quest

X and mantle plumes: the deep quest

Seismic discontinuities necessitates mechanisms that would generate them and therefore, help us better understand the internal structure of the Earth.  This week, Martina Monaco talks about the mysterious X-discontinuity — observed under several hotspots at upper mantle depths of ~ 290 km —and how it relates to the rising plumes. According to the Oxford Dictionary, only 400 words in the English la ...[Read More]

The invisible shield from the centre of the Earth

The invisible shield from the centre of the Earth

The Earth’s magnetic field plays a prominent role in our everyday life. From birds and bees to many modern-day technologies rely on the magnetic field, and yet, our understanding on its long- and short-term behavior is far from complete. In this week’s post, Annique van der Boon shows how geology and paleomagnetic studies can help us in understanding the long-term activity of EarthR ...[Read More]

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]

101 about Ada Lovelace Workshop on Modelling of Mantle and Lithosphere Dynamics

2022 Ada Lovelace Workshop on Numerical Modelling of Mantle and Lithosphere Dynamics is finally coming! Have you got started packing for travelling to Hungary? I got you something to read about on your way to the workshop. Who is Ada Lovelace? The workshop, previously known as the ‘International Workshops on Mantle and Lithosphere Dynamics’, was renamed in 2018 by the EGU Topical Events Committee ...[Read More]
