Folds are among the most strikingly beautiful structures we can observe in rocks. There are several ways folds may form in rocks. For instance, folds in sedimentary rocks may develop by liquefaction of soft sediments, but the most common way to produce folds – and also my favorite – is by deformation. When rocks are compressed by tectonic forces, layers (or foliations) bend and warp, p ...[Read More]

Must-read papers in tectonics and structural geology – Introduction

The “TS Must-read papers” activity can be described as a virtual paper-discussion forum. A total of 103 voters within the TS community nominated 381 “Must read” papers researching topics within tectonics and structural geology, and we, early-career scientists with diverse backgrounds, a.k.a. the TS Must-read papers team (see below), promote in different media the contributions that were the most v ...[Read More]

Analog models for teaching and more, even at home

Analog models for teaching and more, even at home

Ágnes Király is a postdoctoral research fellow at the Centre of Earth Evolution and Dynamics (CEED) at the University of Oslo, Norway. Ági has a background in geophysics, incorporating natural observations with numerical and analog models to study subduction zone processes. Ági has simulated subduction systems mostly in the Central Mediterranean. Working this spring will probably be somewhat diffe ...[Read More]

Call for must-read papers!

    Have you ever read a paper and thought “Why didn’t I find this 3 years ago?!” ? Did you stumble upon TS early-career scientists or colleagues who are unaware of seminal or fundamental (old and new) articles? Or are you simply willing to give some good reading advice about tectonics and structural geology?   IF YOU ANSWERED YES AT LEAST ONCE, THEN THIS IS FOR YOU!   What’s t ...[Read More]

This edition of ‘Features from the field’ is brought to you by Sandra McLaren, a senior lecturer at the University of Melbourne. She will be talking about the volcanic activity and rocks in the Tower hill complex in Australia.   Volcanic activity is one of the most spectacular manifestations of our tectonically active planet. Volcanic eruptions can be highly dangerous when they oc ...[Read More]

The EGU Tectonics and Structural Geology (TS) Early Career Scientist (ECS) team usually write a blog post soon before the yearly EGU General Assembly. This blog post normally helps to highlight a few of the activities that will happen in the General Assembly. As the ECS TS Representative, and in this exceptional year in which the meeting will be virtual, I take this opportunity to provide (i) gene ...[Read More]

In one of the former episodes of the ‘Features from the field’ series we have talked about foliations, and how they develop when rocks are pushed together by the movement of tectonic plates. It is quite uncommon, however, that tectonic forces are active in the same direction for an unlimited period of time. The rule, rather than the exception, is that the orientation of tectonic forces ...[Read More]

In mid-March it was decided that the EGU conference in Vienna was to be cancelled, with an alternative proposed, the online GA. Being the first EGU general assembly to be held online, many people are doubtful about many aspects, such as how the conference will be organised and conducted. EGU has been providing answers to questions on their page and on Geolog, and we thought we would provide some h ...[Read More]

In response to the growing concerns over the spread of the coronavirus and travel restrictions, in-person attendance for the EGU General Assembly 2020 in Vienna has been cancelled. The conference is instead being transformed into a virtual event, where attendees can remotely share their research by uploading presentation material online.  Let’s be honest: digital alternatives don’t replicate the i ...[Read More]

In this edition of “Beyond Tectonics” Ben Blackledge and Hannah Davies talk about worldbuilding and how it can be applied to the discipline of tectonics and tides. Ben Blackledge recently completed his MSc in Bangor and will soon be beginning a PhD in Bristol University.   Let’s begin with a question. Are the tides always the same on every planet? Because of the force of gravity, ...[Read More]
