Water-rock interactions play a central role in many important engineering, environmental, and industrial processes. Geological sequestration of CO2 via carbon mineralization, hydrothermal circulation in (enhanced) geothermal systems, durability of radioactive waste confinement glasses, shale gas recovery, or hydrogen production related to the alteration of (ultra)mafic rocks, are examples of where detailed knowledge of the mechanisms and reaction kinetics involving water-rock interactions are required. This session is intended to address major geochemical issues that remain to be solved for industrial purposes, and basically aims at bringing together recent and novel studies dedicated to the importance and fate of water-rock interactions related to industrial and environmental applications. Contributions can be either experimental or theoretical, ranging from atomic and nm-scale elementary processes to field-scale monitoring and exploitation. Studies aimed at deciphering the kinetics of water-rock interactions and associated mineralogical modifications and chemical fluxes, the coupling between mechanical and geochemical effects of water-rock interactions and upscaling of experimental results are in particular welcome.
