Northeast Asia may be one of the best natural laboratories to investigate both arc and intraplate volcanisms which have developed since the mid-Miocene. The arc volcanoes have occurred above the sinking young (Philippine) and old (Pacific) oceanic plates in Southwest and Northeast Japan subduction zones, respectively. The intraplate volcanoes across the Korean Peninsula and China …[Read More]
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 …[Read More]
Plume craton interaction is a fascinating geological phenomenon. The Indian plate, which has experienced several plume eruptions underneath it, is one of the best locations to study the effect of plume craton interaction. In this week’s news and view, I will provide an overview of the controversy and hypotheses related to the plume craton interaction …[Read More]
Science is all about discovering new things. But how do we make these discoveries, adding to the ever growing pantheon of knowledge? This week, we sit with one of our editors Antoniette Greta Grima, a Postdoctoral Fellow from the University of Texas at Austin, to understand what it takes to discover a new slab process. …[Read More]
Whilst in constant debate with himself on how to address his own insecurities, Harry dabbles in the secret art of interdisciplinary studies. Specifically, mechano-thermo-chemical modeling with the input from experimental studies. Trying to move forward, he struggles: How can we combine all the uncertainties on experimental rock studies with modelling studies? Dear Harry, We can …[Read More]
Stellar storms modify the atmospheric evolution of planets. ‘Hot Jupiter’ planets being very close to their host star, are often affected by such storms. In this week’s peculiar planet, Gopal Hazra, a post-doctoral fellow at the School of Physics, Trinity College Dublin, discusses effect of stellar storms on those planets using his self-consistent hydrodynamic models …[Read More]
Simplified models or toy models explain the complex Earth processes fairly well, even though they are far from reality. In this week’s Geodynamics 101, Adam Beall, Research Associate at Cardiff University, discusses some of his favourite geophysical toy models! I remember being excited to first hear about scientists doing Earth modelling and imagined impressive computer visualisations of …[Read More]
Generation and reversal of the Earth’s magnetic field have remained one of the most controversial topics. In this week’s geodynamics 101, Debarshi Majumder, a PhD student from the Indian Institute of Science, gives a brief overview of the theory of geodynamo reversal and discusses some of the preliminary results obtained from numerical modelling. A planetary …[Read More]
Due to huge difference between the time scale of the mantle convection and the outer core convection, they are modelled separately. In this week’s News and Views, Masaki Yoshida from the Volcanoes and Earth’s Interior Research Center, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Japan, put forward the recent development on the modeling of …[Read More]
PhD students’ struggles are alike; each succeed in their own way[1] It was a Friday morning, and nearly 3 years had passed since I arrived at Sydney. This meant, I only had one month left to submit my thesis! No sooner had I entered my office than a feeling of anxiety had found me. I …[Read More]
