University of Cologne, Germany
11-15 September 2022
GeoMinKöln 2022 – the annual Conference of the Deutsche Mineralogische Gesellschaft (DMG – The German Mineralogical Society) and the Deutsche Geologische Gesellschaft – Geologische Vereinigung (DGGV – The German Geological Society) – will be held 11-15 September 2022 at the University of Cologne, Germany. The DMG Annual Meeting will celebrate its 100th anniversary in 2022 and will return to Cologne, the city where the first DMG Annual Meeting was held in 1908.
Session 4.1 (Magmas and Fluids in the Crust) within Topic 4 (Plate Tectonics and Orogenic Processes) will be co-hosted by iMAGE-CREATE collaborator Dr. Phillipp Brandl, from GEOMAR. The keynote of this session will focus on “Mantle melting responses to ridge relocations at Mid Ocean Ridges”, and will be held by Prof. Alessio Sanfilippo from the University of Pavia. The full session description follows:
Session 4.1: Magmas and Fluids in the Crust
Mantle convection drives the geological processes from rifting of the continental crust, to spreading and the continuous formation of oceanic crust along mid-ocean ridges, to plate subduction and finally collision and orogeny. The partial melting of the Earth’s upper mantle is a common driver to the magmatic processes operating in both the continental and oceanic crust. Mantle dynamics and magmatism thus shape the Earth’s surface and control the long-term geochemical cycles. The heat associated with oceanic and continental magmatism drives hydrothermal activity and the exchange of heat and elements between the Earth’s interior, oceans and atmosphere. However, where melts ascend and ultimately erupt or where fluids circulate is strongly controlled by the crustal architecture, i.e., thickness, permeability and porosity, and tectonic environment. Plate tectonic parameters such as the rate of continental rifting and oceanic spreading or mid-ocean ridge segmentation, for example, result in temporal and spatial changes of magma composition. Recent studies have emphasized the important role of crustal controls on magmatism and hydrothermal activity, e.g., in intraplate settings, at transform faults or arc-backarc settings.
This session aims to bring together contributions from different fields including geochemistry, tectonics, geophysics, and hydrothermal research to trace crustal pathways and the initial formation and evolution of magmas and fluids while they travel through the crust. Studies that combine observations on the modern seafloor with crustal analogues exposed on land (e.g., ophiolites) are particularly welcome.
