Biologic agents mediating matter-flow inside the porous igneous oceanic crust, Vesteris Seamount, Greenland Sea

Hinrich Schmid-Beurmann, Magnus Ivarsson, Wolfgang Bach, Wolf-Achim Kahl & Jörn Peckmann
Microorganisms within the lithosphere are biologic agents settling in niches inside the terrestrial and oceanic crust, populating the extreme environments of the deep biosphere. The fossil record of the permeable igneous oceanic crust, constructed out of primitive extrusive rock, opens a window into Earth’s early evolution and serves as an analogue for life in extraterrestrial worlds. In 2019, samples of highly porous basanites of Vesteris Seamount in the Greenland Sea were retrieved during a cruise...

Radon Emanations from Soils: Case Study of Central Ukrainian Uranium Province

Valentyn Verkhovtsev , Tamara Viktorivna Dudar , Yurii Tyshchenko & Volodymyr Pokalyuk
Ukraine is known as a uranium mining country located in the Central-Eastern Europe. The authors have been studying radioecological situation within the Central Ukrainian Uranium Province where the uranium deposits are located (operated, dormant and perspective ones) for more than 10 years already. Radioecological research, including the radon emanations from soils, allowed us allocating radon-hazardous areas associated with uranium mineralization. The recently studied Mykhailivska ore area (south-eastern part of the Ukrainian Shield) is a unique...

Why are fluid-rock reactions crucial for sustainably utilizing geotechnical potentials of the deep subsurface, and to tackle future energy challenges?

Sebastian Fischer
In recent years, the deep geological subsurface gained more and more attention as it offers various reservoirs potentially applicable for different geotechnical use options, e.g. deep geothermal energy, geological storage of CO2 and H2/energy. In this context, knowledge about the occurrence and the controlling processes of fluid-rock reactions in space and time is important to guarantee sustainable long-term reservoir utilization. While fluid-rock reactions occur at pore scale, they can significantly influence both reservoir-scale (transport) processes...

The chosen approach took into consideration the specific framework conditions...

Current use of geological resources under the view of sustainability - examples from the UNESCO Global Geopark Harz . Braunschweiger Land . Ostfalen

Henning Zellmer & Volker Wilde
When it comes to the mining and use of local geological raw materials, a reflexive, sometimes undifferentiated social rejection arises. The ore, hydrocarbon and coal consumption have now been reduced through recycling and the use of alternative energies or have been replaced by imported products. The last open-cast lignite mine in Schöningen was closed in 2016, the last Harz ore mine in Bad Grund in 1992 and the last iron ore mining in the Salzgitter...

Sustainable mining of sand and gravel in the UNESCO Global Geopark Harz.

Claus Evers & Henning Zellmer
The company Evers und Co GmbH operates two gravel plants in Süpplingen and Uhry / Helmstedt district and thus produces various sands and gravel, topsoil, mineral mixtures and concrete aggregates, among other things. It is also active in the recycling sector, e.g. producing recycled mineral mixtures. An important aspect of sustainability is that the unconsolidated rock for construction work in the region has only short transport routes. This saves massive amounts of CO2. The yield...

Shaping responsible future experts: the need for integrating Geoethics in Geoscience university education

Dominic Hildebrandt
Geoscientific know-how is essential to tackle pressing challenges: climate change, geohazards, energy and raw material supply. However, technical expertise alone – without considering societal dimensions – will not be sufficient to find sustainable solutions to these problems. Geoethics literacy is needed to qualify Geoscientists to work responsibly on complex tasks at the interface to society. Also, Geoethics deals with our own Geoscience philosophy and can therefore help to address current problems in Geoscience academia –...

Scandium and Rare Earths in Major Rivers in Sweden

Franziska Klimpel & Michael Bau
Scandium (Sc) is often included in the group of rare earths and yttrium (REY), but in contrast to the REY, knowledge on its behaviour in the hydrosphere is rather limited. However, a better understanding of the distribution and behaviour of Sc is important, as its use in industry is expected to grow exponentially in future, which will likely result in an increasing Sc release into the environment. Here, we report and discuss Sc and REY...

Sandbox – Creating and Analysing Synthetic Sediment Sections with R

Michael Dietze , Sebastian Kreutzer & Margret C. Fuchs
Geoscientific concepts and hypotheses are usually formulated based on empirical data from the field or the laboratory (induction). After translation into models they can be applied to case study scenarios (deduction). However, the other way around – expressing hypotheses explicitly by models and test these by empiric data – is a rarely touched trail. There are several models tailored to investigate the boundary conditions and processes that generate, mobilise, route and eventually deposit sediment in...

Importance of 3d model management to enable FAIR principles for geological models

Paul Gabriel , Daniel Buse , Björn Wieczoreck & Johannes Camin
A high number of 3d geological models are produced every year at mining companies, geological surveys, consulting offices and many other institutions. Many of these models are being created by different authors and usually have a slightly different purpose and need to meet different demands. Yet the underlying geology stays the same. While the data providers can publish a variety of 2d data sets 3d are lacking behind. This leads to a loss of knowledge,...

GisInfoService – A Web Application of German Aggregates Associations for their Members

Dagmar Kesten
More than 15 years ago the geographical information system GisInfoService was implemented as part of the project ‚GeoRohstoff‘ of the former Commission for Spatial Information Economics (GIW-Kommission). Sponsored by the German Aggregates Associations the purpose of this web application has ever since been to provide the companies of the quarrying industry with relevant spatial information, such as aerial photography, geological and hydrological data or information about land use or conservation areas. Fast access to these...

Jochen Babist & Jutta Weber
The educational role of historical mining sights for sustainable use of geological ressources – examples from the UNESCO Global Geopark Bergstraße-Odenwald In a Geopark, historical mining sights can act as showcase for landscape modification and education for sustainable development (ESD). As elements of the recent cultivated landscape, they provide an excellent motive to discuss aspects of utilization of geological raw materials in actual products, their provenance and related mining and processing. In addition, deep insights...

Traded metal scrap, traded alloying elements: A case study of Denmark and implications for circular economy

Juan Tan
Since metals are often used in alloyed forms, proper management and efficient recycling of metal scrap is key to sustainable management of those alloying metals as well. Previous studies on the trade of metals and metal containing products focused mainly on the carrying major metals themselves, however, the quantity and type of their embodied alloying elements remain rarely investigated. In this paper, we aim to address this knowledge gap by compiling an alloying element composition...

Virtual Outcrop Models - Chances and Challenges for Geoscience School Education

Sylke Hlawatsch
Geoscience has a key role in adressing the challenges of sustainability, yet in German schools a regular subject such as Earth sciences does not exist. Teacher feel uncomfortable with teaching the content and unless an infrastructure for geoscience education - including educational research and systematic teacher training - is implemented in all 16 German states this situation is unlikely to change. Thus geoscience outreach activities play an important role in informing the society about the...

Multi-proxy, localised reconstructions of climate and weathering from cave speleothem samples

Christopher Day , Philip Pogge von Strandmann , Franziska Lechleitner & Heather Stoll
Speleothems (secondary calcium carbonate formations) offer significant potential for recording environmental processes above caves, an area increasingly referred to as the Critical Zone. Speleothems grow for hundreds to millions of years, with absolute chronology from U-Th and U-Pb chronometers. The solution properties of rainwater infiltrating the soil and underlying caves respond to environmental controls. These environmental signals can be preserved within speleothem carbonates. Recent efforts to calibrate, model and interpret this complex geochemistry has progressed...

Palaeofloral response to base level changes in the late Permian Bowen and Galilee basins (Australia)

Alexander Wheeler , Joan Sharon Esterle & Annette Elizabeth Götz
A variety of depositional environments characterise the infill of the late Permian Bowen and Galilee basins. These range from proximal fluvial-floodplain sequences and significant coal deposits through to more distal paralic and marine sections. The uppermost Permian sequence in these basins features spatiotemporal facies shifts but the regionally pervasive nature of the coal seams allows for the examination of the palaeoflora in context of changing environments through time between these bounding surfaces. The predominant flora...

Shallow-marine carbonate cementation in Holocene segments of the calcifying green alga Halimeda

Thomas Mann , André Wizemann , Marleen Stuhr , Yannis Kappelamann , Alexander Janßen , Jamaluddin Jompa & Hildegard Westphal
Early-diagenetic cementation of tropical carbonates results from the combination of numerous physico-chemical and biological processes. In the marine phreatic environment it represents an essential mechanism for the development and stabilization of carbonate platforms. However, many early-diagenetic cements that developed in the marine phreatic environment are likely to become obliterated during later stages of meteoric or burial diagenesis. In this contribution, a petrographic microfacies analysis of Holocene Halimeda segments collected on a coral island in the...

Intragranular halogen (F, Cl, Br), S and δ37Cl variability as determined by SIMS in sodalite and eudialyte from the Ilímaussaq intrusion, South Greenland

Hans G. M. Eggenkamp, Michael A. W. Marks , Thomas Ludwig & Gregor Markl
Halogen (F, Cl and Br), S and δ37Cl variations within grains of Cl-rich minerals sodalite and eudialyte from peralkaline rocks of the Ilímaussaq intrusion were determined using Secondary Ion Mass Spectrometry (SIMS). Samples show either sodalite and eudialyte in direct contact, or sodalite/eudialyte embedded in Cl-free minerals (nepheline, feldspar). Comparing samples allows deciphering potential halogen and S exchange between these minerals during rock cooling. Results suggest that sodalite (7 wt%) and eudialyte (1.2 wt%) have...

Facies analysis and petrography of Permian sandstones - key for stratigraphy and depositional environment of a new tetrapod track site (Southern Permian Basin, Germany)

Sebastian Germann, Jörg Schneider, Birgit Gaitzsch & Michael Buchwitz
The Upper Rotliegend II sandstones of the Mammendorf Quarry in the Flechtingen High near Magdeburg in northern Germany yield an assemblage of continental trace fossils (reptilian and therapsid tracks, scratch and burrow traces). This assemblage is unique in the late middle Permian deposits of Europe and plays a crucial role in the correlation of pre-Zechstein continental deposits and therefore for the global biostratigraphic framework of the middle to late Permian (Schneider et al., 2020). The...

Social licence to operate in the applied geo- and engineering projects

Tobias Rudolph , Jörg Benndorf & Peter Goerke-Mallet
The social license to operate of projects in applied geosciences and engineering has been an issue since the days of Georg Agricola. Its importance for the reputation of companies has increased in recent years. This is due to the public's increased environmental awareness, the desire for more transparency regarding commodity supply chains (circular economy), and especially the perception of catastrophic events such as dam breaches at tailings ponds. The institutionalized and private public's demand for...

Julia Bauer
Every country has a different approach to of climate change adaptation based on local context and needs. This presentation gives an overview how the Netherlands and Germany approach sustainability, and how these differences impacted the energy transition process. Multi-Stakeholder processes have been one of the most crucial features during this process. Germany has proven to be a pioneer in the renewable energy technology and implemented the energy transition through an integrated long-term governance perspective. Public...

Basic implementation for a 3D-viewer with web technology

Michael Wolf , Rüdiger Reimann , Silvia Dieler & Jennifer Ziesch
The presentation of 3D-data is gaining a crucial role for the government agencies in Germany. With the introduction of new federal laws on data storage and release, it became important to present 3D-data in an accessible way to everyone. Since the general public can handle web browser applications easily, unlike desktop applications, web-based technologies should be implemented for data presentation. A good user experience and a valuable access to the data requires that a number...

UNFC resources reporting code and national mineral resources accounting

Janne Hokka & Pasi Eilu
Government organisations compile mineral resource data for national resource accounting. The information is collected and used in research, planning of mineral exploration, and in decision making on national and EU level mineral policies. The data are a combination of publicly disclosed information from active and non-active projects and historical mineral inventories, at extremely variable degree of data density. The databases contain both commercially viable resources and commodity endowments without consideration of economic viability in foreseeable...

Hydrothermal processes related to submarine iron ore formation: Insights from Devonian Lahn-Dill-type ores

Leanne Schmitt , Thomas Kirnbauer , Thomas Angerer , Dennis Kraemer & Sabine Klein
Numerous studies on submarine iron-rich sediments (BIF, ironstones, etc.) focus on environmental changes and ocean chemistry, however, many questions related to underlying hydrothermal processes remain unresolved. As proximal chemical sediments, Lahn-Dill-type iron ores can provide insight into mechanisms of hydrothermal seafloor alteration related metal scavenging, and subsequent Fe-mineral deposition. Lahn-Dill-type iron ores formed during the Middle/Upper Devonian within the Rhenohercynian back-arc basin associated with intraplate alkali basaltic volcanism. Ores formed on top of volcanogenic successions...
