Determining the dynamics of reactive fluid-rock interaction is critical for uncovering the geochemical and geodynamic evolution of the lithosphere and their application in industries like CO2 storage and geothermal energy development. Geological evidence suggests that fluid-rock interactions can self-generate fluid pathways, forming a transient network of pores and fractures through mineral replacement reactions. In my presentation, I will highlight our recent research on: (1) the extent of crystallization forces in positive solid volume-changing replacement reactions, essential for reaction-induced fracturing, (2) the impact of nanoconfinement on the physical properties of geofluids and its influence on rock reactivity, and (3) the latest advances in combining 4D (3D plus time) synchrotron X-ray tomography with advanced deep-learning techniques and statistical microstructural analysis to track transient phenomena in evolving porous media.
