The short story of my PhD

The short story of my PhD

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

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]

Modelling the deformation in the Indian plate and the India-Eurasia collision zone

Modelling the deformation in the Indian plate and the India-Eurasia collision zone

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]

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]
