Scientific Sessions

Roland Barthel (Gothenburg)

This session invites abstracts covering the entire field of hydrogeology, theoretical and applied, quantitative aspects (heads, fluxes, volumes) and qualitative aspects (hydrochemistry, contamination, remediation) and from both fractured rock / bedrock systems and unconsolidated / quaternary systems hydrogeology. Suggested topics are (preferably, but not necessarily with a focus on the Nordic countries) groundwater and climate change, hydrological extremes, groundwater recharge, groundwater modelling, water supply, groundwater surface water interaction, aquifer tests, groundwater monitoring, hydrogeochemistry, analytical techniques, contamination and remediation of groundwater, anthropogenic and geogenic water quality, groundwater and health, and other topics from the field of hydro(geo)logy. We would like to have a special focus on conceptualization and fundamental understanding of hydrogeological systems and their representation in models as well as planning of investigations and projects. Here, we particularly invite contributions from practitioners (consultants, agencies, entrepreneurs) to share best practice examples and problems perceived. We also invite abstracts dealing with education in hydrogeology as well as contributions dealing with international activities and networking.

Magnus Hellqvist, Martin Persson

This session primarily focuses on the practical applications of applied geology in the collaboration between professional geologists, engineers and stakeholders engaged in infrastructure and urban construction projects. It highlights the importance of integrating various aspects of geology (environmental geology, hydrogeology, engineering geology and/or geophysics) to address common geologic challenges encountered by geotechnical engineers, water and sewage professionals or construction specialist. These challenges include optimizing the placement of technical installations and mitigating geohazards. Emphasizing non-academic perspectives, the session specifically underscores the significant roles played by geologic consultants and clients in municipalities or national authorities. Their involvement is essential in effectively tackling these challenges in both ongoing and recently completed projects. By exploring real-world scenarios, this session seeks to enhance and broaden participants’ understanding of how geological knowledge can contribute to the successful implementation of infrastructure projects while promoting sustainable urban development.

Maria Ask (Uppsala), Björn Lund (Uppsala)

There is increasing awareness, internationally and in the Nordic countries, that the green transition requires increased use of the subsurface for energy production and storage. Shallow and deep geothermal energy has the potential to become centrally important in our future energy systems. Large-scale thermal storage can help match energy supply and demand, strongly including time-varying renewables such as wind and solar, as well as handling waste heat and cold from industry and buildings. Other important storage facilities include geological storage for CCS (climate action), for spent nuclear and heavy metal waste (environmental action) and for hydrogen (potential source of energy and critical component of industrial processes). This session focuses on various geological aspects of storage and energy production and welcomes contributions on any of the topics above, with a focus on how geological conditions and risks are assessed and utilized during various stages of facility life time (site investigation, construction, operation, and closure).

Þorsteinn Sæmundsson (Háskóli Íslands, University of Iceland), Reginald Hermanns (NGU, Norway), Greta Wells (Háskóli Íslands, University of Iceland)

Landslides impact every year the Nordic countries, often with very adverse consequences related to large damage to houses and infrastructure and sometimes loss of life. Society is trying to adapt to prevent loss events. However, there is a causal chain from slope instability that is often not easy to recognize over the landslide process itself to secondary consequences such as lake outburst floods, displacement waves that often outnumber the related losses compared to the landslide itself. With this year’s session we want a special focus on the challenges of recognizing potential landslides prior to their occurrence, the possibilities society has today to evaluate the hazard zone including the secondary effects. We especially welcome contributions that focus on the challenge of recognizing potential landslide prone areas and those that include hazard zoning including secondary effects. However, this session is open to all landslide related topics including triggering events such as storms, floods, earthquakes and volcanic activity.

Guri Venvik (NGU), Fredrik Mossmark (SGU)

Urban areas are in constant development, both above and below the surface. Challenges related to the subsurface are multiple and unforeseen ground conditions during construction is one of the primary causes of construction project delays and overspend. Providing relevant and more accessible geological data to the user at the right time and in the right format is crucial to help save money, improve efficiency in planning and development, in resource extraction (water, geothermal, minerals) and to reduce the impacts of geological hazards. Furthermore, it is important to develop platforms for communication between geoscientists, planners, and decision/policy makers. Geoscience-data with data exchange, informatics, and 3D geological modelling for example, by applying the Building Information Modelling (BIM) and City Information Modelling (CIM) is a way to includes the city below ground. Progress on this topic would enhance the use of geological data across the construction, infrastructure and planning sectors and allow a digital connection between surface and subsurface data and models. This session invites projects, research results, data managements etc. related to challenges within applied geology in urban areas or urban geology in general.

Edward Lynch (Luleå, SGU), Axel Müller (Oslo), Martiya Sadeghi (SGU)

Granites and pegmatites are important sources of several rare metals such as Li, Sn, Ta, Nb, W and Cs ‒ many of which are gaining increasing significance for new technologies and the green energy transition. Although granites and pegmatites have been extensively studied in terms of their petrogenesis and metallogeny, work that addresses these issues from a holistic ‘mineral systems’ perspective is warranted to constrain links between melt source areas and generation, melt migration, emplacement mechanisms, and mineralization. This session invites contributions from studies of granite and/or pegmatite mineral systems and their associated commodities, including petrological, mineralogical, geochemical, structural, experimental, and/or geophysical investigations. Integrated studies applicable to mineral exploration or those using new methods and concepts that enhance our knowledge of these important mineral systems are particularly welcome.

European iron ore production is to 90% sourced from iron oxide-apatite (IOA) deposits located in the Norrbotten ore province, northern Sweden, namely the Kiirunavaara, Malmberget and Svappavaara sites. Aside from iron ore, IOA deposits also host significant amounts of P and REEs, both deemed necessary in the efforts to decrease the European import dependency of raw materials and to facilitate the green energy transition. The formation of medium to large-sized IOA deposits and their association with iron oxide-copper-gold deposits (IOCG) remains ambiguous and is surrounded by intense scientific debate. Recent advances using structural and textural approaches, geophysics, geochronology, trace element fingerprinting, and radiogenic and stable isotopes have shed new light on the origin of individual deposits and led to formulations of several overarching concepts. Here we invite contributions that shed light on the origin and evolution of Kiruna-type ore deposits and their association with IOCG deposits in Sweden and abroad, with the aim to review recent advances and discuss strategies for future investigations into this exciting and economically important iron ore deposit type.

Nils Jansson (Luleå), Jukka-Pekka Ranta (Oulu)

This session welcomes all contributions aiming at advancing our understanding of mineral systems and their relationship to past and present tectonic regimes: from the Archaean greenstone belts of Finland to the contemporary Au-bearing precipitates in the geothermal wells of Iceland. Contributions focusing on unravelling ore-forming processes for individual deposits, entire districts, or deposit types of relevance to the Nordic countries are equally welcome. Specific topics include but are not limited to advances in geochronological studies of mineral deposits, structural controls on ore formation and remobilization, stratigraphic analysis of mineralized successions, metamorphism of mineral deposits, research on hydrothermal alteration, fluid inclusions, and improved exploration vectoring.

Ellen Kooijman (Swedish Museum of Natural History), Thomas Zack (University of Gothenburg)

Micro-analytical techniques provide a unique opportunity to obtain in-situ elemental, crystallographic and isotope data for natural materials. This capability has propelled Earth and planetary science to new levels of insight into the history of geological systems, from the grain- to continent-scale, and continues to do so following rapid, ongoing innovation. At present, there barely is any element in the periodic table that cannot be measured, or material that cannot be chemically or crystallographically characterized on the micron-scale. This session is devoted to this great analytical strength and highlights the use of micro-analytical techniques in the Earth sciences, including but not limited to LA-ICPMS, SIMS, EPMA, EBSD, EDS, Raman spectroscopy, and micro-XRF. We particularly invite presentations that explore new research avenues through analytical development or novel applications.

Mafic magmatism is and has been the most common type of magmatism in the world, including in the Nordic countries. Mafic magmatic provinces and mafic volcanism in the Nordics range from Archean greenstone belts in Finland to Mesozoic alkaline magmatism in South Sweden, to Large Igneous Province (LIP)-style magmatism in Norway (e.g. Oslo Rift, Svalbard), the Faroe Islands and Greenland, to submarine Mid-Atlantic Ridge (MAR) magmatism and onshore volcanism on Iceland, such as from the Laki fissure or the 2021-2022 Fagradalsfjall eruptions. This session aims to bring together researchers working on mafic magmatic provinces and active mafic magmatism in the Nordic countries, including those whose work focuses on physical volcanology, petrology, mineralogy, and geochemistry to unravel the origin of mafic magmas (including their alteration) and improve our understanding of the processes involved in their evolution. Studies that highlight the societal relevance of mafic magmatism (e.g. resources and volcanic hazards) are especially encouraged.

The 1.9-billion-year-old Svecofennian rocks have fascinated geologists since the pioneering works of, among others, Törnebohm, Svedmark, Brögger and Holmqvist, more than a century ago. These fascinating rocks provide researchers with a natural laboratory for studies of, for example, volcanism, ore genesis, crustal growth by accretion, inter-orogenic rifting, Paleoproterozoic climate and different types of metamorphism and fluid-rock interaction. The Svecofennian rocks are also of historical and cultural significance, not only as a source of raw materials for various industries ranging from porcelain manufacture to steel production, but also as home to discoveries of several of the elements which underpin the green transition. In this session, we aim to bring together academics working on any aspect of Svecofennian geology. In addition, we welcome non-academic speakers who are engaged with sharing the Svecofennian story with wider society. In view of this transdisciplinary aspect of this session, speakers are asked to pitch talks in a manner which makes them accessible to a wider audience.

Formation of an Archaean Fennoscandian nucleus was followed by fragmentation and reamalgamation of rifted Archaean and newly formed early Palaeoproterozoic terranes during the long-lived and complex Svecofennian and Lapland–Kola orogenies. Active-margin tectonics on and outboard of this Archaean–Palaeoproterozoic cratonic core resulted in significant growth of Fennoscandia before termination during the Sveconorwegian Orogeny. However, the processes by which the Archaean crust formed (e.g., plate tectonics, stagnant lid) and fragmented (e.g., plumes, mantle overturn) are poorly understood. During the late Palaeo- and Meosproterozoic, the Fennoscandian margin constituted part of the Great Proterozoic Accretionary Orogeny (GPAO), that extended through eastern Canada to SW USA, and possibly included cratons of Amazonia, Australia and Antarctica. However, while some argue that the GPAO represents the first modern-style active plate margin on Earth, there is no consensus on the validity of this model, and the operation of alternative, still enigmatic, tectonic modes is possible, suggested by peculiarities such as voluminous massif anorthosites and related granitoids and an apparent stability in environmental conditions. This session welcomes contributions on a diverse set of topics, including structural geology, geochronology and isotopes, geochemistry, metamorphic petrology, geophysics and paleomagnetism, which shed light on the Archaean through Mesoproterozoic growth and reworking of the Fennoscandian Shield and the geodynamics in operation.

Mineralogy is a traditional core discipline of Geology and remains highly relevant to modern society because minerals are the building stones of our planet and essential for the production of almost any kind of commodities used in every-day life. The session embraces all scientific aspects of minerals, with emphasis on – but not limited to – the Nordic area and geologically contiguous regions. Contributions with results from theoretical, experimental, and applied research in mineral science are welcome, as well as new mineral descriptions and taxonomic work.

Matthias Konrad-Schmolke (Gothenburg), Håkon Austrheim (Oslo)

Aqueous fluids are the main transport agent for matter during metamorphism, hence most metamorphic processes somehow involve fluid-rock interaction and an associated element exchange. Quantification of this element transport, -exchange and -fractionation during metasomatism in the Earth’s lithosphere is key to the understanding of the geodynamic and geochemical evolution of our planet. In this session we welcome contributions with a broad focus on fluid-mediated element transport, fluid-rock interaction, and metasomatic rock-forming processes in the Earth’s lithosphere. The session topic might span a wide range of physical and chemical conditions as well as various geodynamic settings within which aqueous fluids interact with rocks and minerals. Process-oriented, regional and/or methodological topics are equally welcome as are cross-disciplinary works. The goal of this session is to bring together a diverse group of scientists from a wide range of fields to discuss the role of fluids in shaping the Earth’s various lithospheric environments.

Although it is well-known that changes in global climate and ocean circulation are closely coupled, many open questions still exist. This is presently clearly illustrated by the sudden actual ‘ocean heat wave’ with surface water temperatures off NW Europe being 3-5˚C higher than normal. Freshwater hosing from ice-sheet melting on North Atlantic overturning circulation has been discussed in many studies. Depending on discharge volume and duration, major consequences for NW European climate have been reported. During the Quaternary, the Greenland Ice Sheet has repeatedly been subject to enhanced atmospheric warming, leading to increased melt water export towards the North Atlantic. This was seen extensively during deglaciations, but also during warm, interglacial periods. For instance, in the Holocene such an episode occurred shortly before 4.0 ka BP, a time of major climate change in NW Europe. An opposite temperature trend between Europe and Greenland in response to atmospheric circulation is another climate feature of the North Atlantic region. While increased storminess and past flooding disasters on the NW European seaboard have been linked to cooling and freshening of the North Atlantic, western North Atlantic surface water warming has been reported contrasting with cold stages of the Little Ice Age in Europe. With these complex ocean-atmosphere interaction patterns as a motivation, we invite marine geologists, (paleo)oceanographers, and Nordic climate experts to submit a contribution to this session to address these questions that are of crucial importance when assessing possible future climate changes in Scandinavia and the North Atlantic regions.

Activities related to offshore windfarm foundations and marine infrastructure are currently witnessing unprecedented expansion and growth for countries to meet their climate targets. The formerly glaciated margins of the Nordic countries belong to the most complex geological settings, as sediment properties are changing on small vertical and lateral scales. A thorough understanding of the shallow subsurface is crucial for reducing costs and improving the infrastructure lifespan of offshore industries. In this session, we welcome contributions on seismic processing and imaging, data interpretation and integration (geological, geophysical, and geotechnical datasets), geohazard assessments, as well as paleogeographic reconstructions with relevance for offshore windfarms and marine infrastructure. We focus on geoscientific innovations facilitating improvements in windfarm and infrastructure site conditions, including the use of artificial intelligence and advanced geo-data integration to improve geo-modelling techniques.

Geoscience education practices primarily develop in the interaction between teachers and students. We move geoscience education forwards as staff and students engage in active learning, adjust teaching and learning activities to suit the context and student dynamic, and innovate to reach learning goals. In this session, we aim to share experiences of challenges, successes, and opportunities, and encourage the spread of good teaching and learning ideas and practices in the geoscience community. This session welcomes contributions on teaching and learning in the geosciences in higher and secondary education. We encourage investigations of your own teaching and learning experiences, such as gamification, and examples of collaboration between staff and students. This session aims to contribute to collaboration in Nordic geoscience education.

This session will focus on geoheritage, as defined by the organization Progeo: the natural heritage of a specific area consisting of geodiversity elements that possess significant geological value. These elements are considered worthy of preservation for the benefit of present and future generations. Geoheritage encompasses both in situ elements, known as geosites, and ex situ elements, such as collections of geological specimens. We will also welcome contributions on the topic of geoparks. UNESCO Global Geoparks are designated areas that house internationally significant geological heritage, encompassing various sites and landscapes. Geoparks are holistic management units that prioritize protection, education, and sustainable development. They adopt a bottom-up approach, actively involving local communities and striking a balance between conservation and sustainable growth. In the Nordic countries alone, there are 13 UNESCO Global Geoparks. We encourage any abstract related to these broad, multi-disciplinary topics, such as geoheritage management and valuation, geotourism, interpretation, geoeducation, collaboration among geoparks, etc.

Understanding the patterns, rates, drivers and dynamics of deglaciation is critical to project glacier response to warming climate and to subsequently model future sea level rise. Glacial sediments and landforms provide important information about the dimensions, distribution and dynamics of past ice sheets and their deglaciation. The aim of this session is to gather researchers working on these palaeo-records (sediments and/or landforms) with a view to reconstructing past ice sheets and their demise. We invite contributions from marine and terrestrial environments, with investigations across all scales (macro to micro), and from all parts of the world. We welcome studies using multi-disciplinary approaches (e.g. field, laboratory, remote sensing/GIS, drones, modelling etc.).

Large volumes of meltwater at or above overburden pressure are increasingly recorded beneath modern glaciers and ice sheets and represent a response to rapid anthropogenic climate warming. Subglacial drainage pathways usually route water efficiently towards margins, but channel capacity is overwhelmed during subglacial floods, briefly generating overpressure, and may produce dramatic impacts at the glacier bed, as seen during jökulhlaups. Overpressured water is recognised as critical for glacier dynamics, including ice-bed separation and sliding velocity, but overpressure is increasingly implicated in many other subglacial processes. Examples include rock and till hydrofracture, glacial erosion, glacitectonics, the formation of soft-bed landforms, the deposition of till and other sediment from pressurised slurries, and in the flushing of deep groundwater aquifers. Yet where, when, and why large volumes of meltwater reached overpressure beneath former Pleistocene ice sheets remain poorly understood. Many puzzles exist about how that water was routed at the bed, the changing dimensions of subglacial conduits, and the non-Newtonian behaviour of overpressured fluid flow. This special session explores the expanding research domain for subglacial overpressured water in modern and ancient glacial systems. Whilst it is appropriate for the NGWM to focus on the Fennoscandian Ice Sheet, and its response to rapid warming during the last deglaciation, we encourage diverse contributions from glaciologists, geomorphologists, hydrologists and from other researchers interested in overpressured fluids in geological settings.

Ancient DNA recovered from sedimentary contexts is a relatively new and cutting-edge approach to understanding entire components of past terrestrial and marine ecosystems at fine scale during the Late Quaternary. The Nordic countries have served as a focal point for this research area, with many of the key discoveries and milestones being made here. In the proposed session, we invite talks about ongoing research from leaders in the field on topics including ecological and environmental reconstructions, taphonomy and preservation, and methodological developments. We will also reserve several talks for up-and-coming ECRs who are active in the field.

Aeolian processes, driven by wind action, shape landscapes and hold valuable insights into past and present environmental dynamics. In recent years, aeolian sediments and landforms have been increasingly studied in the Nordic countries and a new understanding of the impact of aeolian processes on landscape evolution as well as of the potential of the palaeoenvironmental record these deposits hold is emerging. Topics of interest include, for example, the evolution of aeolian landforms, the sources, transport pathways and age of aeolian sediments – ranging from dust to loess and sand – and how this relates to climate change and human impact, including aspects like storminess and forest fire history. The session also welcomes presentations on the impact of storms and storm surges on coastal areas and society, on modelling of wind climate and aeolian processes in the past, present, and future, as well as on methods development in aeolian geology/geomorphology.

Our understanding of past and present climate changes relies heavily on detailed multiproxy studies of past climates from diverse geological archives. In this session, we will bring together all aspects of Quaternary paleoclimate and explore linkages between different parts of the climate system. The session accepts contributions from all aspects of proxy-based climate research as well as modelling studies of Quaternary climate. The session commemorates the work of Professor Svante Björck who passed away suddenly in 2023 and contributions related to his pioneering work on the history of the Baltic Sea, Scandinavian and North & South Atlantic climate and their linkages are especially welcome.

Sedimentology is a versatile scientific field as it is not only found in geology and stratigraphy but also in various other domains, including geomorphology, geophysics and biology. Sedimentary processes and deposits therefore represent an important research topic for understanding the challenges facing societies in the future. Hence, creating a network of sedimentologists of any background and career stage represents an opportunity to enhance research by sharing, discussing and learning together. For this reason, the Nordic Sedimentary Research Group (NSRG), who aims to develop such a network, organizes a special session where sharing knowledge on sedimentology and networking will constitute the core of the session. Speakers are invited to present their work on any topic related to reservoir sedimentology, source to sink sedimentary systems, glacial sedimentology, shallow marine deposits, and the role of sedimentology for CCS; as well as any other sedimentary research relevant for future challenges and the industry. In addition, the NSRG will be introduced to the participants, who will be given the opportunity to discover the different types of events organized by the association.

The metastable mineral ikaite (CaCO3•6H2O) has received increasing interest in recent years due to its peculiar characteristic of preferably forming at near zero °C conditions. It therefore holds the potential of being an excellent mineral indicator of cold climate. This is of special interest for paleoclimate interpretations of the pseudomorphs known as glendonites, found throughout the geological record. Ikaite often precipitates under conditions where other calcium carbonates are inhibited by the presence of certain ions in solution, at high pH, and alkaline and supersaturated solutions. A multitude of parameters, which are not always easily discernible, can lead to ikaite precipitation. Its upper stability temperature treshold is considered to be around 4 – 10 ˚°C above which it alters into the thermodynamically more stable CaCO3 minerals, monohydrocalcite, vaterite, aragonite, and/or calcite. Ikaite’s ability to readily form in cold water and turn into stable carbonates at higher temperature without loss of CO2 are currently being investigated for carbon sequestration usage. Here we welcome all abstracts reporting findings of ikaite and glendonite from geological sites, new data compilations and interpretations on e.g., the geochemical conditions under which they formed, new knowledge gained from laboratory experiments, and innovative ways to utilize this enigmatic mineral.

Earth’s sediment archive preserves the record of past surface conditions. As the surface environment forms the key interface between biosphere and planet, sedimentary rocks are thus the key resource to reconstruct past biotic communities; the environmental and climatic conditions that drove their evolution and the mutual feedbacks between them. We welcome submissions within the broad themes of palaeontology, palaeoenvironments, and palaeoclimate, as recorded in both continental and marine sedimentary successions. Topics may include, but are not limited to: evolution; biostratigraphy; past environmental and climatic change reconstructed from proxies or numerical models; mass extinction events; and methodological advances in geochemical proxies for past environmental, climatic, and diagenetic conditions. We especially encourage multi-disciplinary studies.

Join us for a conference session on planetary geoscience, where we will explore celestial bodies beyond our own. Our goal is to foster interdisciplinary collaborations and inspire new insights into the diverse worlds that populate our solar system and beyond. We welcome contributions focusing on geoscience topics applicable to celestial bodies, including investigations into their surfaces, interiors, and atmospheres. Our session aims to uncover the similarities and differences between these celestial bodies, shedding light on their formation, evolution, and current and past geological processes.

One focus of this session is planetary geomorphology. Researchers are invited to present studies on the morphological features found on planetary surfaces, Moons and small bodies, including experimental results and Earth-analog studies. Contributions discussing ice-related landforms and processes, glacial and periglacial geomorphology, mass wasting, impact cratering and similar phenomena are encouraged.
Additionally, presentations on planetary geochemistry are highly welcomed, aiming to understand the elemental composition and chemical processes within different planetary environments. By exploring isotopic signatures, mineralogy, and organic compounds found on these celestial bodies, we can gain valuable insights into their geological history and potential habitability.

Scientific drilling has been an important component of Nordic Earth Sciences for decades, and major international scientific drilling programs (e.g., IODP/ECORD and ICDP) have had a strong Nordic involvement. Drill cores and in-situ borehole measurements are important for high-resolution studies of the subsurface, addressing scientific topics such as paleoclimate, Arctic environmental change, marine geology and tectonics, ore formation, geothermal energy, CO2 sequestration, and geohazards. Open boreholes are also an important research infrastructure that provides long-term access to the subsurface for environmental, biological, and geophysical studies. In this session we aim to bring together scientists who are involved in borehole-related research and drilling proposals both onshore and offshore. Presentations of industry and geotechnical borehole-related studies, borehole measurements, drilling operations, and associated research infrastructure are also highly relevant. The session will end with an open discussion about the strategy and future of scientific drilling in the Nordic countries and how we are affected by the announced changes in the international drilling programs.

Throughout time, from prehistory to the classical eras of ancient Greece and Rome, human societies have inhabited a wide range of landscapes in different geological settings. The geology of these regions influenced the living conditions of past communities, affecting aspects like mobility, agriculture, and the extraction of raw materials like ores. The natural surroundings also posed risks to their livelihoods through earthquakes, volcanoes, and more. The constraints and opportunities presented by the geology of each region also shaped social structures, because societies adapted to these conditions. This session will explore recent geological approaches to investigating the influence of the natural surroundings on ancient societies. Moreover, we aim to discuss recent research on the skills and observations of ancient humans to gain insights into the extent of their geological knowledge which changed the way they utilized and interacted with the landscapes they encountered.
