The Giant Deer Megaloceros giganteus (Blumenbach, 1799) is an icon of the Ice Age due to their famous antlers, although there has been little focus on isotopic analysis of these animals. migrational behaviour in these animals has been suggested, mainly due to this behaviour being common in deer species today. Migrational behaviour and seasonal movement is analysed in three Giant Deer from Ireland...

Active engagement of students by means of class exercises

Hans de Bresser
Utrecht University, the Netherlands, The Netherlands

In order to improve student learning during lectures on location, students can be actively engaged by giving short class-exercises. Class exercises are just one of the many ways of making lectures more interactive. A good source of inspiration regarding interactive lectures is formed by the quick start-up guides presented at https://serc.carleton.edu/onramps/index.html (NSF funded project). I have ample experience with class exercises in a Structural Geology and Tectonics...

Astronomical climate forcing of ~2.5 Ga banded iron formations

Large-scale banded iron formations (BIFs) were deposited during Neoarchean to early Paleoproterozoic and have been mainly linked to hydrothermal plume activity and the rise of oxygen in the ocean and atmosphere. However, the potential influence of astronomical “Milankovitch”...

The EXCITE-network: providing access to leading-edge electron and X-ray microscopy facilities for geo-materials research

Oliver Plümper , Veerl Cnudde , Geertje ter Maat , Sylvia Walter , Richard Wessels & the EXCITE network
Understanding earth materials is critical to creating a sustainable, carbon-neutral society due to their involvement in many vital processes. Earth materials control the feasibility of subsurface energy storage, geothermal energy extraction, and are a source of critical elements. However, perturbations to geological systems can also result in hazards, such as human-induced earthquakes. If we want to tackle current, pressing scientific questions related to sustainable development for a circular economy, there is an urgent need to...

The data publication chain of the EPOS Multi-scale Laboratories

Geertje ter Maat & the MSL Team
EPOS (the European Plate Observing System) is a pan-European e-infrastructure framework with the goal of improving and facilitating the access, use, and re-use of Solid Earth science data. The EPOS Thematic Core Service Multi-scale Laboratories (TCS MSL) represents a community of European Solid Earth sciences laboratories including rock and magma high-temperature and high-pressure experimental facilities, electron microscopy, micro-beam analysis, analogue modelling of tectonic, geodynamic, and volcanological processes, paleomagnetism, and analytical laboratories. Experimental data from these...

Virtual fieldwork in the Sorbas basin, Betic Cordillera, SE Spain

Liviu Matenco, Meije Sibbel & Hans de Bresser
Utrecht University, The Netherlands

As part of the Earth Sciences curriculum at Utrecht university, first year master degree students get the option to join a Field Research Instruction Geology course in SE Spain. This course focusses on the internal zone of the Betic Cordillera, which is characterized by a spatial alternation of metamorphic ranges and fault-bounded intramontane basins, strongly affected by normal faulting. Every year, several student teams carry out a project in one...

Thermo-compositional models of the West Gondwana cratons

Nils-Peter Finger , Mikhail K. Kaban , Magdala Tesauro , Walter D. Mooney & Maik Thomas
When Western Gondwana broke apart into the South American and African continents ca.120 Ma ago, some of its cratons were broken apart as well. Following the isopycnic hypothesis, their long-term stability and often neutral to positive buoyancy can be explained by the counteracting effects of cooling (density increase) and iron depletion (density decrease). To separate these effects, we created the presented models following an iterative integrated approach using mainly seismic and gravity data. In the...

Decoupled dust deposition and ocean productivity in the Antarctic Zone of the Southern Ocean over the past 1.5 million years

Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages and their role in influencing the carbon cycle. We report the first high-resolution record of dust deposition and ocean productivity for the Antarctic Zone, close to the main dust source, Patagonia. Our deep-ocean records cover the last 1.5 Ma, thus doubling that from Antarctic ice-cores. We find a ≥10-fold increase in dust deposition during glacials and a ≤5-fold...

OneGeochemistry: Enabling a coordinated online global network of multiple distributed geochemical repositories and databases

Kerstin Annette Lehnert , Lesley Wyborn , Dominik Hezel , Alexander Prent , Kirsten Elger , Geertje ter Maat , Marthe Klöcking & Jens Klump
Since the discipline of ‘geochemistry’ was first defined in 1838, geochemical data has been pervasively acquired and used in the Earth, environmental and planetary sciences and become fundamental for understanding past, present, and future processes in natural systems. Initially, geochemical data was published in hard-copy literature, but as analytical systems became computerised, major digital databases emerged (EarthChem, PetDB, OZCHEM and GEOROC) which revolutionised data access. They have proven the power of re-use of geochemical data...

Indentation and transfer of deformation between different orogenic systems: the greater Adria - Pannonian - Carpathians system

Liviu Ciprian Matenco & Douwe van Hinsbergen
Utrecht University, The Netherlands

Indentation is used to define the collisional mechanics of small plates flanked by large subduction systems creating significant thickening and lateral escape of continental units. The close spatial proximity creates a situation where deformation is actively transferred between different subduction systems during their different stages of orogenic evolution. We study this transfer by observation and modelling of indentation and orogenic evolution in the Central Mediterranean system. The evolution of the...
