Various experimental techniques (e.g., Vertical Scanning Interferometry, Electron and Atomic Force Microscopy) and modelling techniques (Monte Carlo and ab initio methods) open up a new field of study on the surface dynamics on minerals, glasses and metals and their role in water/rock interactions. The possibility of direct measurements of dissolution/ precipitation rates at specific locations on the mineral surface provides a better understanding of reactive surface area. The determination of reactive surface area is known to be a central problem in fluid/solid interactions. Quantitative kinetic rate data are urgently needed for modeling water/rock systems that provide a better understanding of the dynamics governing many geologic processes.
