Tetravalent uranium mobilization by complexation or oxidation and associated U isotope fractionation

Yvonne Roebbert , Chris Daniel Rosendahl , Ashley Brown , Axel Schippers , Rizlan Bernier-Latmani & Stefan Weyer
Uranium (U) isotopes are suggested to monitor the success of (bio)remediation relying on the reduction of soluble and mobile U(VI) to less soluble U(IV)1. However, the subsurface stability of U(IV), typically present as solid-phase non-crystalline U, may be affected by complexation or oxidation. Understanding these processes and their impact on U isotope fractionation is important to correctly interpret field U isotope signatures. We investigated U mobilization by complexation and oxidation and measured the associated U...

The carbonatites of South Morocco: Unusual occurrences and associated REE-Nb-Ta-Fe mineralization

Rachid Benaouda , Dennis Kraemer , Maria Sitnikova & Michael Bau
The Oulad Dlim massif in the southernmost part of Morocco hosts several carbonatite bodies of different ages. The older carbonatite (1.85 Ga) occurs in the eastern Oulad Dlim massif in the Gleibat Lafhouda area and consists of three juxtaposed magnesiocarbonatite outcrops. They are associated with glimmerite, hosted by Archean gneiss, and unusually intruded by massive IOA deposits. The latter contains up to several wt% REE related to numerous monazite-(Ce) inclusions within large apatite crystals. Columbite-(Fe)...

Underground Hydrogen Storage (UHS) – status quo and perspectives in Germany

Matthias Warnecke & Simone Röhling
Bundesanstalt für Geowissenschaften und Rohstoffe (BGR), Germany(1);Recently, politics and industry has discussed green hydrogen as one of the carbon-zero energy sources of the future. Besides many other countries, Germany formulates clear goals for the energy transition from fossil to hydrogen energy in its "National Hydrogen Strategy". In order to ensure steady supply of hydrogen and to secure national reserves the underground storage of hydrogen (UHS) is increasingly coming into focus. Germany already has extensive experience...

Hyperspectral analysis of lacquer peel profiles as quasi-in-situ analysis for tailings exploration

Wilhelm Nikonow & Dieter Rammlmair
Three lacquer peel profiles were prepared from a copper tailings deposit in Central Chile. The peels were taken from two sides at varying depths of the tailings heap. Parallel to that, samples were taken from each layer within the peels for bulk XRF analysis and particle size analysis. The peels were analysed by Hyperspectral Imaging (HSI, VNIR- SWIR, 400 – 2500 nm wavelength) with the Specim SisuRock system and µXRF mapping using M4 Tornado Plus...

Microbial H2 consumption at conditions relevant for H2 underground storage

Anja Dohrmann & Martin Krüger
Underground storage of hydrogen could be an alternative way to store large amounts of energy. However, microbial consumption of H2 is still a major uncertainty factor. Since microbial life is widespread in the crust of the earth an underground storage site needs to be seen as a habitat for microorganisms. Microbial activity at the H2 storage site might affect the stored H2 as well as the integrity of the storage site itself. There is great...

Cementation rates of detrital platform carbonates and sequence stratigraphic implications

Thomas Mann & Hildegard Westphal
Different views exist on the prevalent processes that control transport and deposition of detrital platform carbonates in a sequence stratigraphic framework. While some models indicate that meteoric cementation during sea-level lowstands retards sediment transport into deeper basins, others imply marine cementation during highstands as dominant process affecting the architecture of carbonate depositional sequences. These opposing views are based on observations from the Bahamian archipelago, an isolated carbonate platform with a significantly higher carbonate saturations state...

The points presented here correspond to the additional points to Bedmap1 used for the gridding of Bedmap2. The data...

X-ray absorption spectroscopy study of Mn reference compounds for the identification and quantification of Mn species in soils

Teresa Zahoransky , Anna V. Wegorzewski , Winnie Huong & Christian Mikutta
Chemical reactivity, mobility, and bioavailability of manganese (Mn) in the environment depend crucially on its speciation. Despite the broad application of X-ray absorption spectroscopy (XAS) to environmental samples, studies covering the identification and quantification of Mn species in soils are surprisingly scarce. In this study, we analyzed 32 organic and inorganic Mn reference compounds by Mn K-edge (6,539 eV) XAS to assess the potential of XAS to differentiate various Mn coordination environments in soils. X-ray...

Geology across borders - Towards a consistent interpretation of the subsurface in the Central North Sea covering the Dutch, German and Danish offshore areas.

Hauke Thöle , Fabian Jähne-Klingberg , Maryke den Dulk , Hans Doornenbal, Finn Christian Jakobsen & Peter Britze
Geology does not follow national borders and for many areas of application, it is essential to know the characteristics of the subsurface on both sides of the border. In the area of the North Sea, however, consistent interpretation of the subsurface across borders are rare, as most studies carried out here by the Geological Survey Organizations (GSOs) in charge have remained confined to their national territories. As a consequence, the interpretations are often not aligned...

Does regional geology help to assess earthquake hazard in continental interiors?

Tim Hahn, Jonas Kley, Diethelm Kaiser & Thomas Spies
Earthquake hazard assessment is crucial for different planning tasks, including the search for a German nuclear waste repository. Germany is located in an intraplate setting with a low level of seismicity and the seismically active faults are incompletely known. To solve this problem, seismotectonic regions (SR) of assumed uniform seismicity can be defined and used as a basis to define seismic area sources to be used in seismic hazard analyses. We have elaborated a new...

Global reference histograms of the IMS infrasound broadband detection lists

Samuel Kristoffersen, Alexis Le Pichon, Patrick Hupe & Robin Matoza
This data set builds upon the broadband detection lists of the International Monitoring System (IMS)’s infrasound stations.

Large-scale quantification of Li in spodumene pegmatite using Laser Induced Breakdown Spectroscopy

Simon Müller & Jeannet Meima
Spatially detailed surface analysis of geological samples and drill cores offers insight into element and mineral distributions on large scales, an important information in ore exploration processes. Laser Induced Breakdown Spectroscopy (LIBS) is an uprising technology that allows fast in-situ geochemical measurements directly on a sample surface under atmospheric conditions. Since nearly no sample preparation is needed, the technology is suitable for spatially-resolved measurements on large samples such as drill cores. LIBS also allows the...

Covering 15,000,000 km2, the pan-European seas represent a promising new frontier for the exploration of mineral resources. The GeoERA-MINDeSEA consortium, a cooperative network of 12 Geological Surveys and Marine Institutes, is facing this exploration challenge. 688 seabed mineral occurrences are described in the MINDeSEA database, GIS cartographies and reports, containing valuable information on geology, metallogeny, critical raw materials prospectivity and mineral potential. Five types of mineral deposits are investigated, including seafloor massive sulphides, ferromanganese crusts,...

Groundwater exploration and production in arid Jordan

Falk Lindenmaier , Gerhard Kapinos , Mark Gropius , Klaus Holzner , Florian Brückner , Daniel van Rooijen , Rebecca Bahls & Mathias Toll
The water providers of Jordan are constantly seeking to find new water resources to supply the public. Water table depths of up to 250 m, dry aquifers and saline waters make it increasingly difficult to successfully strike exploitable groundwater. We provided geoelectrical measurements for the exploration of a new well field area and set up a preliminary a-priori model for the interpretation of the geoelectrical results. Borehole geophysical logs, data on salinity content and subsurface...

µ-EDXRF based classification of chromites. A quick approach for testing hand specimen and drill cores.

Dieter Rammlmair & Wilhelm Nikonow
Chromites from ophiolites and layered intrusions show a wide variety in Cr#, Mg# and Cr/Fe ratios. These ratios provide information on the genesis of the chromite deposits e.g. the place of formation. By means of µ-EDXRF this information can be obtained in a very quick way from cut hand specimen. Unfortunately, chromites show a number of very intensive diffraction signals due to the polychromatic beam of the µ-EDXRF system, which even after calculating the minimum...

Geophysical borehole logging - using existing data for petrophysical and regional characterisation of claystone formations

Gesa Kuhlmann & Klaus Reinhold
BGR-Dienstbereich Berlin, Germany(1);Claystones in the deep subsurface have various barrier-effective properties for solute transport. Changes in the mineralogical composition (incl. fluids), the structure of claystones in the strict sense, as well for claystone formations in a broader sense, and their regionally different geological development cause a great variety of petrophysical, mineralogical and geochemical properties of claystone sequences. Therefore, sound knowledge of the characteristics of claystone formations is required for the different usage options of the...

On the infrasound emission generated by wind turbines

Lars Ceranna , Peter Gaebler, Gernot Hartmann, Patrick Hupe, Christoph Pilger & Andreas Steinberg
Aerodynamic infrasonic signals generated by wind turbines can be detected by highly sensitive micro-barometers showing spectral peaks at the blade passing harmonics, which are above the background noise level. As infrasound is one of the four verification technologies for the compliances with the Comprehensive Nuclear-Test-Ban Treaty (CTBT), decreases in detection capability for dedicated infrasound arrays have to be avoided. Therefore, preventing such decrease is particularly important for the two German infrasound stations IS26 in the...
