The Nordic countries face a varied spectra of geohazards, spanning from geophysical types such as volcano eruptions and earthquakes in Iceland over to quick clay landslides in Norway and Sweden, rockslides and related displacement waves in Norway and Iceland. In addition, the Nordic countries are exposed to extreme weather conditions, such as storms with high wind speeds, heavy rainfall and fast temperature changes that often result in landslides, flooding and coastal erosion. This session aims at presenting a wide range of geohazard studies in the Nordic countries and Arctic regions, including case studies from various geographical, geological and topographical settings and more general evaluations of geohazards from a Nordic perspective. The session is open for all types of geo and natural hazards present in the region.

Weathering and alteration of Earth materials in the rock cycle provides the substrate and most of the necessary compounds for life. The processes are controlling factors in the near-surface environment where water, rock, air, and life meet in a dynamic interplay; generating soils/ecosystems and shaping landscapes. Weathering is also responsible for generation mineral resources (Al, Fe, Ni, Cu, P, clay minerals), many of which are of vital importance for advanced technologies. In glaciated areas weathering products may constitute an important part in glacial deposits and have an impact in geochemical exploration for ore deposits. Physical-chemical phenomenon are not limited just to surface processes but alteration of buried primary rocks and minerals, often associated with biological agents, may reach the deep subsurface. Understanding the physical-chemical and biological processes that affect the weathering and alteration is important across a large range of problems, from assessing soil sustainability over timescales of human observation, to quantifying feedbacks between climate, weathering and tectonics over billions of years on Earth and beyond. These studies are coming more and more interdisciplinary bridging a broad range of disciplines, from mineralogy to biochemistry. All aspects of weathering phenomena and their research methods are welcome contributions to this session.

Geologists understand the landscape. To us, the surrounding scenery tells the story of Earth, thus enabling us to understand the inner works of Tellus and hence making us aware of possible threats and challenges that our only home encounters. Alas, for most humans this story remains hidden, making public awareness of geosciences important. Geology helps to understand essential fields to our existence which include climate change, food security and ground water pollution. Additionally geology influences daily lives in unexpected ways, e.g. by providing tools to investigate the availability and access to mineral resources.
         The vast geodiversity is one of the most striking manifestations of geology, but it can also be observed in the form of natural resources that we use as products of geosystem services. However, the excitement with geotourism, landscapes, fossils, minerals and rocks is shown by general public of all ages.
         Since 1990's the need for public awareness of geosciences has been growing, and there are several initiatives and methodologies applied in many countries in order to try to raise it up by disseminating geology in accessible way for all.
         The Nordic Winter Meeting is delighted to yet again host a session dedicated to Geological outreach. Contributions are invited from all fields, including methodologies, experiences, theoretical approaches, and research that aim to raise the public awareness of geosciences in the natural, as well as in the urban environment.

Data concerning individual Archean intrusions, areas, suites and specific events of the Fennoscandian Shield has cumulated significantly during the last two decades. These results do not always fit into the proposed geologic scenarios of the overall development of the area, thus we encourage contributions that refine or redefine the existing areal models. But as also numerous detailed questions still remain unanswered, this session welcomes also contributions of more detailed studies that potentially contribute to the building of the wider geological picture.

The Archean-Proterozoic transition encompasses 500 Ma of Earth history with substantial changes both in endogenic and exogenic regimes, leading to the establishment of the modern-style Earth system. These changes were linked to the cooling of the mantle and environmental perturbations related to the Great Oxidation Event at ca. 2.3 Ga. The time period is characterized with a variety of geological and geochemical phenomena, including changes in the composition of volcanic rocks, disappearance of mass-independent fractionation of sulfur isotopes in sedimentary rocks, widespread deposition of glacial diamictites, marine carbonates with unprecedentedly heavy carbon isotope values, iron formations, and organic-rich shales. The Fennoscandian Shield provides an excellent geological record to study the global events that occurred during the Archean-Proterozoic transition. Contributions on all subjects relevant to advancing our understanding of this exciting stage in Earth history are welcome.

Studying the evolution of Proterozoic orogens is a continuous task. Growing amounts of new isotopic, structural and geophysical data as well as analog and numerical modelling necessitate to refine the existing concepts for the individual orogenic belts. Moreover, interpretations of Phanerozoic orogens may generate fresh ideas for their Proterozoic counterparts. Typically, there exist several competing models and the new data may be in favour of either one. Proterozoic orogens also serve as reliable keys for the reconstruction of supercontinents and supercontinental cycles. Since the session covers a wide spectrum of geological research, we invite contributions in various fields of appraising Proterozoic orogens and their role in Earth's evolution.

The first age estimates of Precambrian rocks in Fennoscandia were obtained already half a century ago by Olavi Kouvo and Erik Welin. The results obtained showed a large range of ages and formed the basis for understanding the geological evolution, but many results were also ambiguous and introduced further questions. Since the setup of NORDSIM twenty years ago several problems in dating complex crustal history have been solved, but challenges still remain e.g. with rocks which don't carry zircon. Precise dating using the U-Pb system is still a key for many questions. Recently, large amounts of U-Pb data have been obtained by the ICPMS method, but what is the real precision and accuracy of the method compared to TIMS and SIMS and how should the non-specialist decide which of these complementary methods to use for any given project? Presentations and discussion on this field are welcome.

The climate in the North-Atlantic — Fennoscandian (NAF) region is highly dynamic. The region has experienced significant changes in sea level, ocean circulation, temperature, precipitation, snowfall and glacier extent. Many studies suggest that these changes in the NAF region may affect the global climate system, demonstrated for example by the inception of the Quaternary glaciation in the northern hemisphere, the Heinrich events, and the rapid climate changes during the last termination. This session will bring together contributions that deal with reconstructions and simulations of past climate both in the marine and continental domains based on palaeoclimate model output and proxy archives. Presentations are welcome on topics such as Pre-Quaternary and Quaternary palaeoclimatology, glacial and interglacial temperature patterns, palaeohydrology, abrupt climate changes, and climate-ecosystem interactions. We particularly encourage papers employing data-model comparisons to understand the mechanisms and forcings of past climate changes, comparisons of marine and continental data, and papers focusing on the application of new analytical techniques and novel proxies. We welcome relevant contributions from all parts of the world, but particularly want to support scientists focusing on palaeoclimate studies in the North-Atlantic — Fennoscandian region and in the adjacent regions in North Europe to present their results.

Minerals and melt inclusions record an archive of magmatic and volcanic processes that are invisible at the whole-rock scale. Recent advances in micro-analytical in-situ techniques (e.g., LA-ICP-MS, SIMS, microdrilling) have revealed considerable trace element and isotopic diversity in crystal populations, individual crystals, and inclusions preserved within them. In-situ geochemical studies of minerals and chilled melts at microscopic scales have thus opened a new realm of detail in deciphering the evolution of igneous systems — up to the scale of the igneous evolution of planetary bodies. We invite contributions from igneous petrologists who have used in-situ geochemical analysis in their research of magmatic systems. We also welcome contributions that concentrate on the development of applications of these methods to frontier problems of igneous processes. The fields of research may also cover, e.g., estimations of pressures and temperatures of magmatic systems, deciphering volatile contents of magmatic inclusions, and determinations of ages of crystal populations. We hope that this session will draw the attention of a large group of forefront igneous petrologists and spur new and integrated studies of igneous systems.

Mafic to ultramafic inrusions have been one of the most important metal sources for the mankind. Significant amounts of nickel, copper, chromium, titanium, vanadium, iron and platinum-group elements have been mined from deposits hosted by the mafic-ultramafic intrusions. Amount of these deposits in the Fennoscandian Shield is notable: the numerous old nickel mines in Norway represent the early history of mining, followed by the world-class Petsamo nickel-copper mines in Russia. In Finland the huge Kemi chromium deposit and Kevitsa Ni-Cu-PGE deposit are mined at present, Mustavaara and Otanmäki have produced vanadium, titanium and iron, many promising PGE-deposits are hosted by the ca 2.45 Ga mafic to ultramafic layered intrusions, and several Svecofennian (1.9 Ga) Ni-Cu deposits have been mined. The recent discovery of the Sakatti Ni-Cu-PGE deposit significantly raised the potential for new discoveries in northern Finland. This session introduces the varied and sometimes amazing origin of the mafic-ultramafic intrusions and related ore deposits around the world.

During the Quaternary much of the Northern Hemisphere has been repeatedly affected by ice sheets that contributed to erosion in the highlands, deposition in the lowlands and shaping the Earth's surface over distances of thousands of kilometres. Although the spatial extent of glacial deposits and landforms is well established, the knowledge of specific processes that created them is often fragmentary. We invite contributions dealing with all aspects of glacial sedimentology, glaciotectonics and geomorphology with emphasis on process interpretation. The topics may comprise but are not restricted to the origin and properties of glacial tills, water-laid glacial deposits, erosional landscapes and drumlins; interactions between the glaciers and their beds including the issue of fast ice flow and subglacial hydrology; and runoff and pro-glacial lake sedimentation. Studies of both modern and past glacial environments from all geographical regions are welcome. We encourage submissions that utilize innovative techniques to better understand glacial environments, such as drones, laser and radar scanning, time-lapse photography, new software, etc.

The Quaternary period spanning the last 2.5 million years has been characterized by oscillation between glacial and interglacial phases. Versatility of the environmental conditions throughout the period has yielded to an equally versatile set of chronological methods to obtain time spectra of Quaternary events. Variety of methods have developed from a mainly technical advances to quantitative analysis tools of even Bayesian nature and this all has supported the rise of transdisciplinary research. This session provides a platform for scientists to present their results related to dating methodologies and chronological tools concerning the Quaternary period.

Understanding the vertical movements of the earth's crust is one of the most exciting in modern-day geoscience. In our region, the debates have been focused on the age and origin of the Norwegian mountains, but clearly, our understanding of vertical movements and onshore-offshore relations of the entire region are of importance for deciphering the underlying processes; e.g. the Norwegian margin, Svalbard, the Barents Sea, the Danish Basin as well as areas that are traditionally considered as stable cratons such as Sweden and Finland — not to mention Iceland and Greenland. In this session we aim at providing a forum for the uplift debate based on observations and on geodynamical models that may demonstrate the active mechanisms behind these enigmatic movements. We welcome presentations about the burial and exhumation history of the region, about interpretation of the large-scale landscapes, about the timing and nature of weathering processes and about mechanisms that may explain the observations.

Modern mountain systems provide the foundation for our understanding of ancient orogens, where information available to understand their evolution is limited. However, the present-day form of Plate Tectonics may not have existed earlier in Earth's history when the interior of the Earth was hotter and key tectonic features such as subduction zones may have differed from their current form. Thus, in order to understand the potential differences in tectonic styles, ancient orogens that form the shield areas of many continents require detailed study using a wide variety of methods. In this session, we invite presentations focussing on the evolution of the lithosphere of modern as well as ancient orogens. We welcome contributions on the dynamics of plate motions and the resulting orogeny that use (i) numerical and analogue modelling, as well as (ii) geological and/or geophysical laboratory- and field-based methods.

The formation of rifted continental margins by extension of continental lithosphere leading to seafloor spreading is a complex and still poorly understood component of the plate tectonic cycle. New observations and modelling allow us to investigate the underlying processes. Key questions that need to be resolved include 1) factors that control the geometry and crustal architecture or rifted margins, 2) the role of strain localisation and strain partitioning throughout the rift history, 3) processes responsible for anomalous vertical motions during basin evolution such as phase changes or small scale convective instability of the mantle lithosphere, 4) fundamental controls on the magmatic or a-magmatic nature of rifts and passive margins, 5) interaction between surface processes, tectonics, and climate during rift-passive margin evolution. We encourage abstracts that offer new insights into crustal and lithospheric architecture and processes underlying rifting and passive margin formation as well as smaller scale studies of individual sedimentary basins, using constraints from observations and modelling.

Modern imaging methods at different scales allow the quantitative characterization of bedrock, offering new opportunities to model geological structures in 3-D. A range of 2-D and 3-D methods have been developed to visualize nanoscale textures in rocks to orogen scale structures. For example, lab- and synchrotron based X-ray computed micro- and nanotomography are emerging techniques to precisely image the interior of rock volumes in 3-D. On the other hand, ''structure from motion'' based aerial photogrammetry, airborne LiDAR and terrestrial laser scanning, high-resolution geophysical (gravity and magnetic) images and seismic profiles are popular imaging tools in geological mapping and 3-D modeling. We solicit contributions to this session on imaging technologies from field-based, experimental, analogue and numerical research at all scales. Advancements in analytical imaging techniques (e.g., SEM, EPMA, LA-ICP-MS) related to microtectonics are also welcome!

Impact cratering has significantly contributed to the formation and reshaping of planetary bodies in our Solar System, including planet Earth. Impact cratering is a process that has affected the geological environment throughout the evolution of our planet at different scales and times. We invite presentations that are related to all geological aspects of impact cratering. These may include the formation processes of impact structures in various target platforms such as water, ice, sedimentary cover or crystalline rock. Topics related to defining the projectile type, understanding the existence of doublet craters on Earth and defining the geophysical, geochemical, petrophysical, mineralogical and isotope characteristics of terrestrial impact structures are also included. Discussions on shock metamorphism phenomena, post-impact hydrothermal processes as well as field and remote sensing case histories with multidisciplinary approaches, are welcome.

Climate, erosion and tectonics have been proposed to interact on a number of spatial and temporal scales, notably through (1) the couplings between orographic precipitation, focussed erosion and tectonic activity predicted by numerical models of active mountain systems, and (2) the global-scale feedbacks between physical and chemical weathering, consumption of carbon dioxide and Cenozoic climate cooling. These provocative hypotheses have attracted great scientific interest, but definitive evidence of the causal relationships between these processes has been difficult to find both in the field and laboratory. In this session, we invite presentations from researchers studying the relationships between climate, erosion and tectonics at all spatial and temporal scales using numerical, laboratory and field-based methods.

The present-day Earth as we see it with its continents and oceans is just a snapshot in time of a continuously evolving planet. It is now clear that there have been several supercontinents throughout its history prior to Wegener's Pangaea: Neoproterozoic Rodinia, late-Paleoproterozoic-Mesoproterozoic Columbia/Nuna and perhaps the late Archaean Kenorland. To the present session “Supercontinents through time” we invite oral presentations or posters on geological, geophysical or isotopic hints of ancient supercontinents, making reconstructions of supercontinents as based on palaeomagnetics, geological or isotope age correlations, or (ideally) integrating these approaches. We also invite contributions on the processes behind supercontinent formation and break-up: plate tectonics, plume tectonics, and underlying mantle geodynamics, as well as questions about growth, evolution and destruction of continental crust.
