---Excuse multiple postings--- Dear colleagues, We would like to make you aware of the session 1.4 “Multi-scale, dynamic interactions of minerals with fluids: From the shallow subsurface to the deep Earth” at GeoMin Köln 2022 (www.geominkoeln2022.de<http://www.geominkoeln2022.de>). This year we will be celebrating 100 years of the German Mineralogical Society (DMG) in the beautiful city of Cologne, Germany. Reactions between fluids and minerals have a fundamental impact on many natural and geo-engineering processes within the lithosphere. Examples of natural processes encompass the localization of deformation, earthquake nucleation caused by high pressure fluid pulses, as well as metamorphic reactions and rheological weakening triggered by fluid flow and fluid-mediated mass transport. Moreover, the efficiency of many geo-engineering processes is partly dependent on fluid-rock interactions, such as geothermal energy recovery, CO2, and hydrogen storage as well as wastewater injection. To fully quantify and determining the operating mechanisms that govern fluid-rock/fluid-mineral interactions within natural and geo-engineered systems we need to take a multi-scale, multi-dimensional approach coupling observations, experiments, and models at the nanometre-scale with observations at larger length scales. We invite multidisciplinary contributions that investigate fluid-rock/fluid-mineral interactions across the full spectrum of length scales, including natural observations, microstructural and microchemical investigations, experimental approaches as well as numerical models from ab initio to the continuum scale. We particularly encourage studies that take a dynamic approach to fluid-rock/fluid-mineral interactions by using in operando techniques and studies that using machine learning for multi-scale analysis. Deadline for abstract submission is Tuesday 31st May 2022. Our keynote speaker will be Anna Harrison, Geosciences Environment Toulouse CNRS.
