Reactions between fluids and rocks control many natural processes shaping and modifying Earth. Examples include the fluid-induced rheological weakening of plates, the localization of deformation, earthquake nucleation and the triggering of metamorphic reactions. Recently, the importance of quantitative knowledge controlling fluid-rock interactions is increasingly being recognized for geo-engineering processes affecting the environment. Examples include geothermal energy extraction, hydrogen and CO2 storage or nuclear waste management. Defining the physico-chemical processes governing fluid-rock interactions requires an innovative combination of knowledge and techniques across the full spectrum of geoscience disciplines to determine the mechanisms and rates of fluid-rock interaction and its consequences on system Earth.

We invite multidisciplinary contributions that investigate fluid-rock interactions using fieldwork, microstructural and geochemical analyses, experimental petrology and rock mechanics as well as atomistic- and continuum-scale modelling.
