Plate tectonics from a perspective of continental crustal growth

An illustration of what we know about plate tectonics on Earth by Hee Choi.

Understanding the plate tectonics initiation can give us incredible opportunity to guess the physical state of the early Earth. This week, Hee Choi, a Ph.D. candidate, takes us on a journey on initiation of plate tectonics and how continental crustal growth is related to it. Our planet Earth is the only place where plate tectonics takes place. No other planet or rocky moon in our solar system has ...[Read More]

The short story of my PhD

Ömer F. Bodur and edited by Anna Gülcher May 3, 2021

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 had no time to dig deep into my own thoughts to discover what was happening, although it was obvious. Instead, I re ...[Read More]

The boundaries of plate modelling

This weeks post is all about the importance of boundaries. Plate boundaries that is. Jean-Christophe Wrobel-Daveau and Graeme Nicoll tell us why we should care where plate boundaries are and how they evolve through time, when attempting to reconstruct past plate motions. Global plate tectonic models are an incredible way to synthesise geological knowledge to gain both direct and indirect insight i ...[Read More]

A complete fluid dynamical approach of modeling the Earth’s deformation can not provide a complete picture due to presence of rigid lithospheric plates. In this week’s news and views, Srishti Singh, scientist at National Geophysical Research Institute, India, explains how coupled models of lithosphere dynamics and mantle convection are developed. The ongoing collision of the Indian plate wi ...[Read More]
