Extensional tectonics at oceanic transform faults: a new perspective on plate tectonics

Extensional tectonics at oceanic transform faults: a new perspective on plate tectonics

Yu Ren is a PhD candidate at GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany. He uses three primary tools to study marine tectonics: geomorphology, seismology, and numerical modelling. His PhD project is on the structural and tectonic characterization of oceanic transform faults.   Oceanic transform faults (OTFs), usually considered as first-order tectonic segmentation of mid-ocean r ...[Read More]

The Makran accretionary wedge: an ideal natural laboratory to study accretionary processes.

The Makran accretionary wedge: an ideal natural laboratory to study accretionary processes.

How does an accretionary wedge form? For this edition of Minds over Methods, we have invited Jonas Ruh, lecturer in the Structural Geology and Tectonics group of the Geological Institute at the Department of Earth Sciences, ETH Zürich, to tell us about the Makran accretionary wedge, one of the largest on Earth. He explains how the use of field observations and numerical modelling helped him to bet ...[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]

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

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

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]

Minds over Methods: Dating deformation with U-Pb carbonate geochronology

Minds over Methods: Dating deformation with U-Pb carbonate geochronology

For this edition of Minds over Methods, we have invited Nick Roberts, a research scientist at the British Geological Survey, working within the Geochronology and Tracers Facility (GTF) running a LA-ICP-MS laboratory. Nick has a background in ‘hard-rock’ geology, incorporating geochemistry, geochronology, and magmatic and metamorphic petrology across a wide range of tectonic settings, and is now in ...[Read More]

Minds over Methods: Virtual Microscopy for Geosciences

Minds over Methods: Virtual Microscopy for Geosciences

The next “Minds over Methods” blogpost is a group effort of Liene Spruženiece (left) – postdoctoral researcher at RWTH Aachen and her colleagues Joyce Schmatz, Simon Virgo and Janos L. Urai. The Virtual Microscope is a collaborative project between RWTH Aachen University and Fraunhofer Institute for Applied Information Technology (Schmatz et al., 2010; Virgo et al., 2016). In the ...[Read More]

Minds over Methods: The faults of a rift

Minds over Methods: The faults of a rift

Do ancient structures control present earthquakes in the East African Rift?  Åke Fagereng, Reader in Structural Geology, School of Earth and Ocean Sciences, Cardiff University For this edition of Minds over Methods, we have invited Åke Fagereng, reader in Structural Geology at the School of Earth and Ocean Sciences, Cardiff University. Åke writes about faults in the Malawi rift, and the seismic ha ...[Read More]

Minds over Methods: Mineral reactions in the lab

Minds over Methods: Mineral reactions in the lab

  Mineral reactions in the lab André Niemeijer, Assistant Professor, Department of Earth Sciences at Utrecht University, the Netherlands In this blogpost we will go on a tour of the High Pressure and Temperature (HPT) Laboratory at Utrecht University and learn about some of the interesting science done there. André’s main interest is fault friction and all the various processes that are invol ...[Read More]

Minds over Methods: Massively dilatant faults in Iceland – from surface to subsurface structures

Minds over Methods: Massively dilatant faults in Iceland – from surface to subsurface structures

In this Minds over Methods we don’t have one, but two scientists talking about their research! Michael Kettermann and Christopher Weismüller, both from Aachen University, explain us about the multidisciplinary approach they use to understand more about massively dilatant faults. How do they form and what do they look like at depth? Massively dilatant faults in Iceland – from surface to subsu ...[Read More]

Minds over Methods: Tectonochemistry of Melting Mud in the Mantle, evidence from the Oman/UAE ophiolite

Minds over Methods: Tectonochemistry of Melting Mud in the Mantle, evidence from the Oman/UAE ophiolite

For this first Minds over Methods of 2019, we invited Christopher Spencer, Senior Research Fellow at Curtin University in Australia, to tell us something about tectonochemistry. By applying geochemistry to tectonic processes, it is possible to get more insight into the different stages of the rock cycle. By combining fieldwork and geochemical analyses of the Oman/UAE ophiolite, Chris and his co-wo ...[Read More]
