Prof. Dr. Martin Dietzel 2 Overall Research Interests Research interests are focussed on solid-liquid interaction as well as the mechanisms and kinetics of neo-formation and dissolution of solids. This comprises experimental studies as well as investigations in natural systems. The topics are devoted to fundamental research with special regard to environmental or applied aspects. Fields of research and teaching activities are mineralogy, hydrogeochemistry, chemical sedimentology, geochemical modelling, applied mineralogy with focus on distribution of trace elements and stable isotopes, solid-liquid interaction, soil chemistry, (paleo)environmental research, formation and stability of colloids and silica polymers, and marine evaporates.
