Petrology and Geo-/Cosmochemistry

Meteorites and the early solar system
Convener: Addi Bischoff, Thomas Kruijer & Knut Metzler (Münster/DE)

Information obtained from meteorites is crucial to better understand the earliest history of planet formation and evolution. This session will be devoted to the research results on all kinds of meteoritic matter, i.e. interplanetary dust, differentiated and undifferentiated meteorites. We invite contributions on the petrography, mineralogy, chemistry, and isotopic composition of meteorites and their components in order to better understand the early stages of accretion (including formation of refractory inclusions and chondrules), melting, differentiation and aqueous alteration as well as late, secondary processes (e.g., breccia formation) on meteorite parent bodies.

The mineral record of impact events
Convener: Dennis Harries (Jena/DE) & Ralf-Thomas Schmitt (Berlin/DE)

We invite contributions to the understanding of how high-velocity impact events are reflected in the mineralogical, geochemical, and microstructural make-up of the shocked target rocks and impactites. The session will cover the broad topics of shock metamorphism, characteristic microstructures, impact glasses and tektites, the tracing of impact events from distal and proximal ejecta, and the post-impact alteration of crater lithologies - from natural samples, to theory, to experiments.

Stable and radiogenic isotopes - clocks and tracers of rocks
Convener: Andreas Pack (Göttingen/DE) & Carsten Münker (Köln/DE)

Analytical advancements in radiogenic and stable isotope geochemistry combined with improved modelling approaches are currently leading to a wealth of advances in earth science fields like planetary formation, crust-mantle differentiation, evolution of the oceans as well as paleoenvironmental reconstructions. The session aims presenting new and exciting results of geochemical studies covering a large variety of applications across these fields. Contributions documenting new analytical and theoretical developments are particularly welcome.

Magmatic petrology - from melt to rock
Convener: Gregor Markl (Tübingen/DE) & Francois Holtz (Hannover/DE)

The session "Magmatic petrology - from melt to rock" deals with all aspects of magmatic processes, from melt generation via crystallization to emplacement, including all kinds of field or structural, petrological, geochemical and experimental studies. Studies on element partitioning and volatiles in magmatic systems are particularly welcome.

Metamorphic rocks: petrology, geochemistry, geochronology
Convener: Hans-Peter Schertl (Bochum/DE) & Reiner Klemd (Erlangen/DE)

Subduction drives plate tectonics, creates continents and transports lithospheric rocks to the Earth's mantle. Thus, it is one of the most important geodynamical processes on Earth. In this session, we aim to follow subducting slabs on their journey from the surface down into the deep Earth and back towards the surface. Examples of questions we seek to address in this session are: What is the role of metamorphism and how do fluids and melts influence it? Which are the controlling parameters in respect to the rocks involved? What is the fate of subducted crust, sediments and volatiles? With this session we aim to deepen our knowledge about subduction-related processes by combining insights from metamorphic petrology, geochemistry, mineralogy, and geochronology. Therefore, we invite contributions from a wide range of geoscientific disciplines, in order to discuss the role of metamorphism at all scales from surface to lower mantle and back.

Minerals – fluids – rocks
Convener: Timm John (Berlin/DE) & Thorsten Geisler-Wierwille (Bonn/DE)

This session is aimed to bring together researchers who are interested in understanding the fundamental processes of fluid-mineral and fluid-rock interaction like metasomatism, metamorphism, weathering, consequences of CO2 sequestration, or the aqueous durability of individual solid phases such as materials used to immobilize nuclear waste on different length and time scales. We welcome field-based studies as well as experimental and theoretical studies of fluid-solid interactions, fluid properties, or of transport processes from deep mantle to surface environments. The session aims to explore mechanisms of fluid-induced chemical/isotopic changes in minerals and rocks over a range of conditions to evaluate textural consequences as well as element mobility and mass transport.

Minerals in the environment – from geo- to biosphere
Convener: Erika Kothe (Jena/DE),Giovanni de Giudici (Cagliari/IT) & Juraj Majzlan (Jena/DE)

The interaction between minerals, aqueous solutions, gases, organisms and organic matter controls the environmental behavior and fate of elements and pollutants. This session will highlight the complex relationships among the geogenic background (rocks), human activities, hydrosphere, atmosphere, biomineral interfaces, biomineralization processes, and biological interaction and toxicity of hazardous minerals. We seek case and laboratory studies on polluted system; molecular- to field-scale approaches with applications in natural, medical and/or engineered settings are encouraged.

General Mineralogy and Crystallography

Microstructures, textures and interfaces of minerals
Convener: Rainer Abart (Wien/AT) & Andreas Lüttge (Bremen/DE)

Interfaces such as mineral-water contacts or grain- and phase boundaries are the locations where mineral reactions take place. Equilibrium thermodynamics and the kinetics of interface processes control microstructure, texture and chemical evolution during crystallization and dissolution and, thus, determine many of the physical and chemical characteristics and behavior of geological materials. Analytical and computational techniques with ever increasing precision and spatial resolution offer new perspectives for unraveling the information content of mineral surfaces, interfaces, and textures. We invite contributions addressing the role of surfaces and interfaces in mineral reactions, microstructures, and texture evolution. This call includes also studies on the reactivity of mineral surfaces at ambient conditions and the mechanisms underlying metamorphic reactions. The session will focus on methodological developments as well as applications to minerals, rocks or their synthetic analogs.

Mineral physics and the deep Earth´s interior
Convener: Monika Koch-Müller (Potsdam/DE) & Tomoo Katsura (Bayreuth/DE)

Understanding mineral physics at the P, T conditions of the deep Earth is of crucial importance to interpret geophysical observations and to construct a dynamic model of our Earth. We invite contributions from experimental as well as computational studies focusing on physical properties of the minerals of the deep Earth and their influence on the geodynamics

Crystal structures and properties of materials
Convener: Robert Dinnebier (Stuttgart/DE) & Maria Wierzbicka-Wieczorek (Jena/DE)

The session is dedicated to present crystal structure refinements of minerals or inorganic compounds based on powder or/and single crystal X-ray diffraction as well as to discuss the structure-property relations in materials sciences.

Mineralogical crystallography
Convener: Thomas Malcherek (Hamburg/DE) & Ronald Miletich (Wien/AT)

Modern crystallography provides a rich set of tools for the determination of mineral structures, using diffraction, computation or spectroscopic methods.
The session invites contributions concerned with the structural characterization of minerals. Of particular interest are studies dealing with the evolution of structural properties of minerals as a function of temperature, pressure or composition.

Modern techniques for mineralogical research
Convener: Jörg Göttlicher (Karlsruhe/DE) & Christoph Berthold (Tübingen/DE)

The session will cover the ongoing developments in materials characterization from both, the chemical and structural point of view. Complementary analysis with combined methods to gain simultaneous insights into structural and chemical properties of various kinds of materials, from geological to technical nature will be one focus. Also, the current progress in improving and optimizing local resolution, detection limits, and measurement times as well as extending measurements conditions to low and high temperatures, pressure or different atmospheres will be another topic in this session. Contributions are welcome that report on instrumental innovations and/or data processing in laboratories, field environment (mobile devices), or in large scale facilities like synchrotron or neutron radiation sources for material characterization.

Mineralogical museums and collections
Convener: Birgit Kreher-Hartmann (Jena/DE) & Jochen Schlüter (Hamburg/DE)


Applied Mineralogy

Functional materials
Convener: Bernd Maier (München/DE) & Bernd Marler (Bochum/DE)

The session will serve as a discussion platform for studies on the synthesis, characterization, structure-property relationship, and application of functional materials. These materials which may be of natural (minerals) or synthetic origin include semiconductors, magnetic materials, catalysts, shape memory alloys, sensors, adsorbents, materials for energy storage/conversion and many others. Any kind of functional material and all types of characterization methods are welcome for presentation. We expect an interesting session covering a large variety of subjects.

Technical mineralogy – cements, ceramics and glasses
Convener: Stefan Stöber (Halle/DE) & Achim Kleebe (Darmstadt/DE)

The performance, stability and efficiency of cements, ceramics or glasses strongly depend on the qualities of their starting materials and process parameters; i.e., the mineral properties, applied pressure, temperature or specific environments, as well as, most importantly, the resulting final microstructure. This session aims to provide a forum for researchers, who study the correlation between processing, microstructure and performance (even at harsh environment) of such industrially relevant material classes. In particular, contributions in the field of cements, structural-, functional-, or electro-ceramics and novel glass systems are invited to present newest results. Apart from materials performance, contributions on synthesis, characterization and microstructural analysis (structure and chemistry) are welcome.

Economic minerals: formation, characterization, and applications
Convener: Michael Meyer (Aachen/DE), Jens Gutzmer & Bernhard Schulz (Freiberg/DE)

This session on economic minerals will explore recent advances in both fundamental and applied studies across a wide range of areas involved in the origin, anatomy, and inventory of ore and industrial mineral deposits as well as in the application of mineralogical and mineral-chemical methods to exploration, exploitation, ore dressing, and waste management. It will be the platform for the presentation and dissemination of research focusing on the formation of ore-grade concentrations of economic minerals, quantitative mineralogy, mineral technology, and the environmental impact of resource exploitation. The session on economic mineralogy will also afford
participants an opportunity to exchange ideas, open up collaborative ventures, and develop partnerships, both with academia and industry.

Archeometry and monument conservation
Convener: Frank Schlütter (Bremen/DE) & Gert Klöß (Leipzig/DE)

Archaeometry is now a well-established field between science and the humanities. Among others many mineralogical and geochemical methods are used for studies of all kinds of archaeological materials. Especially the variety and complexity of archaeological artifacts including ceramics, glasses, pigments, metals, stone fragments, and other materials induces the necessity of a broad range of analytical tools to answer archaeological questions concerning material identification, manufacturing processes, provenance analysis, dating and authentication. Many topics in the field of monument conservation, e.g. stone conservation, preservation of wall paintings, plasters and mortars are closely related to the mineralogy.
For this session we invite contributions from the whole field of archaeometry and monument conservation as well, covering e.g. artifact studies regarding provenance analysis, production technology, dating methods, stone deterioration, inorganic binder materials, pigments, case studies. Also, contributions regarding the application of new analytical techniques are welcome.
