High Resolution Imaging of the Pedernales Earthquake Rupture zone

Understanding the physical processes that control the behavior of subduction zone megathrust faults remains one of the outstanding challenges in Earth sciences. These faults generate the largest earthquakes and giant tsunami (e.g. Mw 9.5 Chile 1960, Mw 9.2 Alaska 1964, Sumatra 2004 Mw 9.1, Mw 9.0 Tohoku 2011). Furthermore, deformation along megathrust faults is ultimately responsible for mountain building processes which generate the longest and tallest mountain ranges on Earth and therefore shaping Earth surface...

Data from: Evolution of flexible biting in hyperdiverse parasitoid wasps

Thomas Van De Kamp, István Mikó, Arnold H. Staniczek, Benjamin Eggs, Daria Bajerlein, Tomáš Faragó, Lea Hagelstein, Elias Hamann, Rebecca Spiecker, Tilo Baumbach, Petr Janšta & Lars Krogmann
One key event in insect evolution was the development of mandibles with two joints, which allowed powerful biting, but restricted their movement to a single degree of freedom. These mandibles define the Dicondylia, which constitute over 99 percent of all extant insect species. It was common doctrine that the dicondylic articulation of chewing mandibles remained unaltered for more than 400 million years. We report highly modified mandibles overcoming the restrictions of a single degree of...

Data from: Population biology of establishment in New Zealand hedgehogs inferred from genetic and historical data: conflict or compromise?

Barbora Bolfikova, Adam Konečný, Miriam Pfäffle, Jasmin Skuballa & Pavel Hulva
The crucial steps in biological invasions, related to the shaping of genetic architecture and the current evolution of adaptations to a novel environment, usually occur in small populations during the phases of introduction and establishment. However, these processes are difficult to track in nature due to invasion lag, large geographic and temporal scales compared with human observation capabilities, the frequent depletion of genetic variance, admixture and other phenomena. In this study, we compared genetic and...

Helmholtz Open Science Briefing: Helmholtz in der Nationalen Forschungsdateninfrastruktur (NFDI): Report des Helmholtz Open Science Forums

Eine wichtige Rolle spielt dabei auch die Abdeckung disziplinübergreifender Querschnittsthemen. Zur Förderung des Dialogs zur NFDI in der Helmholtz-Gemeinschaft veranstaltete das Helmholtz...

Ressourcenschonende Batteriekreisläufe – mit Circular Economy die Elektromobilität antreiben

Kwade Arno, Christian Hagelüken, Holger Kohl, Matthias Buchert, Christoph Herrmann, Tilmann Vahle, Reinhard von Wittken, Matteo Carrara, Steven Daelemans, Helmut Ehrenberg, Sarah Fluchs, Daniel Goldmann, Georg Henneboel, Julia Hobohm, Michael Krausa, Johanna Lettgen, Kerstin Meyer, Manuel Michel, Marcel Rakowski, Markus Reuter, Dirk Uwe Sauer, Michael Schnell, Magnus Schulz-Mönninghoff, Paul Spurk, Wassilij Weber … & Susanne Kadner
Heutige Produktions- und Konsummuster folgen weitgehend einer linearen Logik: abbauen, herstellen, konsumieren, entsorgen. Nur neun Prozent der Weltwirtschaft sind laut Circular Gap Report 2020 kreislaufgeführt. Doch dieses Wirtschaftsprinzip trägt zu einer massiven Überschreitung der „Planetaren Grenzen“ und damit zu einer Destabilisierung der Ökosysteme und Lebensgrundlage der Menschen bei, wie etwa des Klimasystems und der Artenvielfalt. Demzufolge wird derzeit viel über einen Paradigmenwechsel in der Logik industrieller Wertschöpfung diskutiert – weg von einem ressourcenintensiven hin zu...

Characterization of pore space in sandstone using the anisotropy of magnetic susceptibility

Julius Schenk , Agnes Kontny , Benjamin Busch , Ilner Khasanov & Hagen Steger
The pore space in siliciclastic rocks is one of the most important petrophysical properties in reservoir rock characterization. Of particular interest is the 3D distribution of pore space and permeability for the purpose of reservoir model development. We used a magnetic technique to determine the preferred orientation of the pore space. The approach is based on the injection of a magnetic ferrofluid, which is a stable colloidal suspension of approx. 10 nm-sized magnetite particles, into...

Au biaxial compression 30% engineering strain

Wolfram G. Nöhring, Adam R. Hinkle & Lars Pastewka
This surface is the result of a Molecular Dynamics simulation of bi-axial compression of single crystal Au. The initial configuration was an Au cube with side length 100 nm. The x- and y-directions of the simulation cell were parallel to the [-110] and [-1-12] directions of the crystal, respectively. The z-direction was parallel to the [111] crystal direction. The x- and y-directions were periodic, but the z-direction was free, hence the crystal had free surfaces...

Performance of manganese oxide sorbents for direct lithium extraction from geothermal brines

Klemens Slunitschek , Jochen Kolb & Elisabeth Eiche
Lithium is one of the critical elements for the realization of electric mobility and energy transition. With a contribution to global Li-production and recycling of less than 1% (2017), Europe depends almost entirely on Li-import. To reduce the dependency, new and unconventional Li resources are explored in the EU. One resource are highly saline brines from geothermal reservoirs of the Upper Rhine Graben (URG), characterized by Li concentrations of up to 200 mg/L. Due to...

On-site hydraulic and mechanical characterization of a claystone around a non-lined test tunnel in Mont Terri, Switzerland

Sina Hale , Xavier Ries , David Jaeggi & Philipp Blum
The rock mass around man-made underground structures inevitably experiences major changes in hydraulic and mechanical properties, commonly referred to as excavation damage. In host rock formations for underground nuclear waste storage, such an excavation damaged zone (EDZ) is potentially critical and therefore requires reliable field data sets for safety assessment and the estimation of the long-term behavior. In this study, different on-site measurements were carried out in the EZ-B niche of the Mont Terri Rock...

Reservoir characterization of the coal-bearing Upper Carboniferous clastic succession, Ruhr area, Germany

Jonas Greve , Benjamin Busch , Dennis Quandt & Christoph Hilgers
Structural Geology & Tectonics, Karlsruhe Institute of Technology(2);Due to the closure of coal mining in the northwestern German coalfields, active mine water drainage becomes technically redundant. As a result, the rising mine water table affects the subsurface stress conditions and may induce heterogeneous ground movements of fault blocks. Petrophysical properties of the Upper Carboniferous (Westphalian A and B) rocks are crucial to understand subsurface behavior during mine water rise. As a part of the interdisciplinary...

Regional deformation imprints from anisotropy of magnetic susceptibility data – an example from the Raichur Schist Belt (Dharwar Craton, India)

Santu Biswas, Manish A Mamtani , Agnes Kontny & Christoph Hilgers
The Raichur Schist Belt (RSB) is a NW-SE trending late-Archaean greenstone belt that forms part of the supracrustal units lying over an older gneissic basement. Granites (ca 2.5 Ga) occur in the vicinity of the RSB. The metavolcanics and granites are both massive and lack a field foliation and/or lineation. To work out the time-relationship between emplacement, fabric development and regional deformation of the granite vis-à-vis metavolcanic rocks and regional deformation, we performed Anisotropy of...

Europäische Versäumnisse bei der Erschließung und Bewertung neuer Lagerstätten. Interview

Jochen Kolb
Auch mit modernsten Technologien benötigen Geologen mindestens zehn Jahre, um einen Rohstoff als Reserve oder Ressource der Industrie bereitstellen zu können. Europa investiert bisher wenig in die Bewertung und Erschließung eigener Lagerstätten. Mit einer Änderung dieser Philosophie ließen sich auch viele Umweltprobleme in Entwicklungsländern vermeiden, die der Bergbau dort verursacht. Der Lagerstättenkundler Prof. Dr. Jochen Kolb vom Institut für Angewandte Geowissenschaften des Karlsruher Instituts für Technologie (KIT) im Interview.
