FIB preparation of a surface
Mineral surfaces are places of chemical exchange between different reservoirs (Earth's crust and mantle, oceans, atmosphere). The interaction of (mostly aqueous) solutions or gases with minerals includes elementary reactions like dissolution and growth, adsorption and ion exchange. They are of central importance for a number of geological but also technical processes.
