Neutrons and X-rays: 3D and 4D imaging in geoscience

Anne Pluymakers April 6, 2020

In-situ 4D Neutron imaging of imbibition of heavy water in an Indiana limestone (Cordonnier et al., 2019).

Anne Pluymakers is an assistant professor at TU Delft, whose hobbies include experimental rock mechanics and fluid-rock interaction. She focuses on the effects of fluids on mechanical behaviour of rocks at representative in-situ temperature and pressure conditions, with a strong focus on hydrochemical fluid-rock interaction. Investigating the microstructure of the rock and how it is altered is cri ...[Read More]

Mind your head: Taking care of yourself during the Corona-virus crisis

By now more and more countries in Europe are hit by the Corona-virus, leading to increasingly strict measures and closures of many public places. We are being asked or obliged to work from home, to limit social contact by staying away from bars, restaurants, sports clubs, museums, theatres and all other places where gatherings of people take place. Simultaneously, we continue to receive worrying m ...[Read More]

Zürich, with its lake stretching towards the foot of the Swiss Alps in the South, is currently a charming city full of watersides, lively bars, students and bankers. In Switzerland, you’ll find a wide variety of landscapes and geological features over a relatively small area – from the Alpine mountain range in the South to the low-lying plateau and the Jura Mountains in the North. Located in close ...[Read More]

In October 2019, an open letter was published, addressing both EGU and AGU regarding their policy to reduce the carbon footprint of their annual conferences. Almost 2000 scientists already signed this letter, asking for more ambitious measures to decline carbon emissions, in line with the goals of 50% reduction by 2030 and near-zero emissions by 2050 (IPCC SR15, 2018). Some of the proposed improve ...[Read More]

Beyond Tectonics: How mountain building shaped biodiversity

This edition of “Beyond Tectonics” is brought to you by Lydian Boschman. Lydian is a postdoctoral researcher at ETH Zürich. She has a background in geology and plate tectonic reconstructions, but now works with a group of biodiversity modelers of the Landscape Ecology group at ETH, bridging the gap between geology and biology. In her research, she focuses on the uplift history of the Andes, and ho ...[Read More]

Sendai, living on the edge!

Sendai and its people live on the edge. The city and its citizens learned to live over a subduction zone. Sendai has survived 500 years of hazards; it is a resilient and industrious city. People know disaster will strike again, but also that they will rise up when it does. Japan, ‘the sunrise country’, would be much better named ‘the land of sinking tectonic plates’. Above the point where the Paci ...[Read More]

Features from the field: Bedding/Stratification

Bedding (also called stratification) is one of the most prominent features of sedimentary rocks, which are usually made up of ‘piles’ of layers (called ‘strata‘) of sediments deposited one on top of another. Every stratum is characterized by its own lithology (composition), sedimentary structures, grain size and fossil content that make it unique and different from the stra ...[Read More]

On top of a steep cliff standing out from the surrounding countryside, lies the small town of Civita di Bagnoregio, one of the most famous villages of Italy. It is often called the dying town, although more recently people have started to refer to it as fighting to live. What this little town is fighting against is the threat of erosion, as its walls are slowly crumbling down. Located in central I ...[Read More]

Bangor and Snowdonia, a natural laboratory for geologists of the scientific revolution

Bangor, once a tropical paradise on the coast of Gondwana, then a volcanic wasteland at the foothills of an immense mountain chain. The region would then be buried under glaciers for thousands of years before finally developing into an unassuming Welsh University town. Wales’ place in modern geology Perhaps you have looked at the chronostratigraphic chart of Earth history and wondered what ...[Read More]

Geothermal Energy and Structural Geology?

Fieldwork is a necessity to expand the brain, to kick-start 3D thinking. Field studies with a specific application in mind have – until now – usually been geared towards hydrocarbon reservoirs. However, with the increasing use of the subsurface, for example for CO2 storage and geothermal energy, alternative field studies gain importance. Here, we will focus on geothermal energy, which is in ...[Read More]
