Crystal structure of clay minerals
Convener: Kristian Ufer, Eric Ferrage
This session will be devoted to the recent advances in the quantitative characterization of complex and/or defective structures of clay minerals and other lamellar compounds. New insights into the crystal structure derived from numerical simulations, combined or not with other commonly used techniques, are also relevant to this session.
Clays, reservoir rocks and energy issues
Convener: Pieter Bertier, Andreas Busch, Reinhard Gaupp, Georg Grathoff
This session covers all topics related to the physical and chemical interactions of fluids with clay minerals in reservoirs and caprocks utilized for storage of CO2, H2, and natural gas and for production of conventional and unconventional hydrocarbons. Experimental, theoretical, and sedimentological studies of processes including but not limited to clay hydration/dehydration, fluid-organic-clay interactions, sorptive gas uptake, and wettability of clay minerals in contact with gases or fluids at ambient and/or reservoir conditions are welcome. We are particularly interested in topics covering in-situ experimental studies that combine simulated reservoir conditions with real time observations and case studies using new analytical tools and experimental approaches studying the dynamics of reservoir rocks.
Clays in geotechnical applications
Convener: Michael Plötze, Tom Schanz
Because of their special properties clays play in the field of geotechnical engineering an important role, as "ground" material in the classic tasks of civil engineers in the field of structural and fundamental soil mechanics, as a building material or in environmental geotechnics. The session focuses both on theory and practice. Aspects of modern analytical modeling as well as lab and field testing research will be covered. The presentation of problems and solutions in applications e.g. in ground improvement and of other case studies are welcome.
Stability of engineered clay barriers in radioactive waste disposal
Convener: Reiner Dohrmann, Patrik Sellin
Stability of the properties of engineered clay barriers in radioactive waste disposal is a basic requirement for the long term safety of disposal of radioactive waste. Processes affecting the stability of engineered clay barriers are studied by research groups worldwide in lab experiments as well as in large or full scale experiments in underground or hard rock laboratories. The aim of the symposium is to give an insight into these systems.
Clay minerals in diagenetic and low temperature metamorphic environments
Convener: Rafael Ferreiro Mählmann, Laurence Warr
The description of the low temperature alteration of clay minerals during burial diagenetic and very-low grade metamorphic (VLGM) processes in sedimentary and volcanic rocks are able to elucidate the thermal evolution of sedimentary basins and orogenic wedges. The large volume of fluids and volatiles that pass through parent rocks can cause drastic changes during early to late diagenetic alteration of clay deposits and associated hydrocarbons, and with increasing temperature these reactions continue into the realm of metamorphism, where mass transport and recrystallization processes predominate. This session aims to further our understanding of the controlling parameters of clay mineral alteration and reaction progress in contrasting geological environments (e.g, temperature, fluid chemistry, rock deformation, microstructures) by hosting relevant contributions presenting field case studies, experimental/kinetic approaches, and thermodynamic modelling.
Clay minerals in hydro- and geothermal systems
Convener: Albert Gilg, Michal Skiba
Clay minerals are important tracers of fluid-induced thermal anomalies in the upper continental crust. They record hydrothermal processes in fossil and present-day geothermal fields and reflect the composition of the involved fluid.
Clay mineral research thus becomes increasingly significant in exploration for mineral deposits and thermal energy. The session will cover all aspects of clay science in the field of hydrothermal and geothermal systems.
Analytical tools for improved characterization of clays and clay minerals
Convener: Katja Emmerich, Arkadiusz Derkowski, Georgios Chryssikos
The physical and chemical properties of clays are determined by compositional, structural and morphological heterogeneity which extends from the local nanoscopic to the macro scales. Evidently, the characterization of this heterogeneity requires an interdisciplinary approach and benefits from the synergy of techniques. Various types of diffraction, spectroscopy, imaging, thermal analysis and other methods, often combined with distinct sample pre-treatment, have been effective. This session is devoted to methodological progress aiming at the comprehensive structure/property characterization of clays and clay minerals.
Convener: Stephan Kaufhold, Ralf Diedel
The session „Industrial clays“ will cover all scientific and engineering advances in the field of clays. The presentation of innovative production processes leading to superior clay based products will be as welcome as new scientific results being relevant for the clay industry, including analytical tools useful for the clay industry.
Clays and clay-sized minerals in soils and young sediments
Convener: Karin Eusterhues, Goran Durn, Robert Mikutta
Clay minerals and hydrous Fe, Mn and Al oxides control many environmentally important processes such as the cycling of nutrients, metals and organic pollutants. However, their identification and characterization is still a challenge. The same applies to other natural nanoparticles, whose role in soils and sediments is not yet fully understood. We therefore welcome both presentations about the identification and structure of reactive soil/sediment minerals as well as process studies addressing their interactions in the environment.
Properties and processes at the aqueous interface of clay minerals
Convener: Thorsten Schäfer, Helge Stanjek
At temperatures ranging from ambient to hydrothermal systems almost all important chemical reactions occur at the interface between minerals and water. Therefore, a full understanding of surface properties of clay minerals is essential for describing and modeling processes at the aqueous interface. For this session we invite contributions, which augment our general knowledge about surface properties and processes.
Convener: Jan Srodon, Reinhard Kleeberg
The general session will cover all possible contributions to clay science and education, which will not fit any of the specialized sessions.
