Reaction mechanisms and process monitoring at mineral-fluid interfaces in anthropogenic settings

The interdisciplinary approach of combining expertise in environmental, geochemical, civil engineering and material sciences realizes a new level of in-depth process understanding of the prevailing biophysicochemical reaction mechanisms occurring at mineral-fluid interfaces in various anthropogenic settings such as (geo)technical and construction surroundings. Proposed investigations may focus on the interaction of solid - liquid - gas interfaces, on proxy-based forensic reconstruction and adaptation of variable and possibly unfavorable environmental and operating conditions of different spatial and temporal scales. The advanced process understanding of mineral – environment (abiotic and/or biotic) interactions, combined with newly developed and state-of-the-art environmental monitoring tools (e.g. sensor-based high-resolution data acquisition) enables the target-oriented and customized optimization and development of sustainable material alteration prevention strategies (e.g. advanced inorganic binder systems) and durable mineral-based construction materials, as well as measures against unwanted mineral formation (e.g. plugging of geological reservoirs or drainage systems). In this scope, contributions on advanced environmental monitoring strategies and tools (e.g. sensor systems, isotope/elemental tracers), processes at critical fluid-solid interfaces and high-resolution chemical, (micro-)biological, mineralogical and micro-/nanostructural analytics (e.g. FEG-EPMA, X-ray microtomography), as well as field-based testing, laboratory experiments and modelling approaches are cordially invited.
