Tectonic plates are in perpetual motion, constantly reshaping the Earth’s surface over vast geological – and even within short human – timescales. How do tectonic plates shuffle and shape the face of our planet? Is it a steady, gradually evolving process, or are there sudden events where pronounced changes in the motion of tectonic plates take place?

Prof. Derya Gürer and her team are investigating these questions at plate boundaries in mountainous regions and in the depths of the ocean. Their goal is to decipher current geodynamic processes while also documenting the Earth’s history over long geological timescales. To do so, their research spans spatial scales from the microstructure of minerals to the architecture of entire orogenic belts.

In this talk, datasets and approaches that allow us to track the evolution of subduction plate boundaries from the seafloor to mountain summits will be presented from case studies in Anatolia, New Caledonia, and a recent IODP Expedition that drilled the Japan Trench.

 

 

Prof. Dr. Derya Gürer leads the research group “Geodynamics” and the new “heiMAG” Laboratory for Earth Magnetism at the Institute of Earth Sciences at Heidelberg University since 2024. Her research group combines field-based observations with laboratory experiments on tiny magnetic minerals. She holds a BSc. from Bonn, MSc. from Oslo and PhD (2017) from Utrecht University.
