Geochemistry of the Earth's Surface (GES) 12th International Symposium

ETH Zurich (Switzerland), 25 - 30 July, 2021 


GES12 brings together world-leading scientists in all fields of surface geochemistry and environmental geochemistry. The conference has a strong focus on interactions between the Earth’s spheres: the lithosphere, hydrosphere, atmosphere and biosphere, and how these interactions respond to changing environmental and climate conditions. The overarching theme of GES12 is Earth system interactions on a changing planet.


The conference aims to strengthen connections between research disciplines and to establish new networks. GES12 presents eight themes at the forefront of research and features invited plenary talks covering a wide range of cutting-edge research themes. The extensive poster and networking sessions give ample opportunities to discuss newest research highlights and innovations and to visit the exhibitions.
