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 within the Indian plate since the mid-Cre ...[Read More]

Orphaning: Discovering New Subduction Processes
Figure 1: P-Wave tomography by Obayashi et al. (2013) and Fukao & Obayashi (2013) for Tonga. Note the deflected slab at 660 km depth underlain by deeper slab material, possibly orphan slabs.

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.  Thanks for sitting down with us this week! First things first, which subductio ...[Read More]

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
The 1977 World Ocean Floor Map created by Bruce Heezen and Marie Tharp

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]
