A study of its enamel microarchitecture in several clades (Chiroptera, Afrosoricida, Eulipotyphla, Didelphomorhia, Cetartiodactyla) revealed, apart of considerable taxon-specific variation, a set of structural (i-iii) and developmental (iv-x) characteristics common to all: (i)...

New ways to find geoscientific information in Europe. GeoERA GIP-P Search System

Angel Prieto & Margarita Hernández
IGME, Spain

This contribution concerns Neotethys palaeogeography in the Central Internal Hellenides. Neotethys oceanic crust is represented in the Vardar zone of the Hellenides by the ophiolites of the Almopias sub-zone. Contrary to numerous tectonic models in the literature, we show that the Almopias ocean closed in two episodes.

Applications of virtual reality to Geoscience

Claudia Ruiz-Graham
Imaged Reality

Field trips are essential for geologists and engineers to develop interpretation skills and to get a sense of scale. Unfortunately, attendance to field trips has become less frequent due to cost, with only a handful of team members attending a field trip once or twice a year. Sometimes access to key outcrop analogues can be difficult or too hazardous. COVID-19 has made attendance to field trips even more challenging. An alternative solution...

Phase mixing in the Lanzo upper mantle shear zone (Italy)

Sören Tholen & Jolien Linckens
Goethe-Universität Frankfurt, Germany.

How fine-grained, well-mixed (ultra)mylonitic layers in the upper mantle form is still unclear. Here, microfabrics displaying the transition from porphyroclasts to mixed assemblages were analyzed regarding their phase assemblage, grain size and shape, mixing patterns and crystallographic orientations for insights into the interplay of phase mixing and recrystallization. Olivine recrystallization starts in porphyroclastic textures and continues until ultramylonites. Ol microfabrics are divided in neoblasts in multiphase assemblages, recrystallized porphyroclasts and...

The changing role of Petroleum Geoscietists and Engineers in the Energy Transition

Eilard Hoogerduijn Strating
Shell Upstream Netherlands

The transition towards a zero carbon footprint energy system will greatly impact the energy mix we will use. Globally, a significant increase is expected in the contribution of electrical power (supplied by renewable sources such as solar and wind), bioenergy, nuclear energy and other sources such as hydro power and geothermal energy. However it is expected that the energy mix still contains a significant component of fossil fuels to enable processes...

To understand the evolution of lake basins, a robust age-depth model is essential. Usually, such model is created based on core material using various dating techniques (e.g. radiometric dating, magnetostratigraphy, tephra dating/identification, biostratigraphy etc.). However, suitable core material is not always available and other less direct methods have...

Utrecht University, The Netherlands (1); Unviersity of Bergen, Norway (2)

The Eocene–Oligocene Transition (EOT, ~34 Ma), is marked by the rapid development of semi-permanent Antarctic ice-sheet1. Foraminiferal stable oxygen isotopes (δ18O) as well as Mg/Ca and other indicators (e.g. ice-rafted debris) indicate the development of permanent glaciation that potentially coincides with ~2.5 °Cdeep-sea cooling2. However, due to the nature of the δ18O proxy, uncertainties in the Mg/Ca concentrations of the palaeo-seawater, and calibration...

An anatectic model for albite-spodumene pegmatites from the Austroalpine Unit (Eastern Alps)

Tanja Knoll, Benjamin Huet, Ralf Schuster & Heinrich Mali
Geological Survey of Austria, Austria (1); Department of Applied Geosciences and Geophysics, Montanuniversität Leoben (2)

Albite-spodumene pegmatite are considered to be the product of extreme fractionation of melts or fluids deriving from large alkaline granite intrusions. Anatectic melts deriving from partially molten metasediments are in contrast not believed to be a possible source for such pegmatite. In the Austroalpine Unit of the Eastern Alps, albite-spodumene pegmatite are associated with simple pegmatite and relatively...

Armenia is a country strongly affected by landslides, but still not enough research has been done on landslide susceptibility in this area. Therefore, the main goal of the study was to create one of the first landslide susceptibility zonation maps covering the entire territory of Armenia. Two different data mining techniques for landslide susceptibility analysis were applied: artificial...

Geoethics and the responsibility of Geoscientist in society: from research to teaching and outreach

Clara Vasconcelos (1) & Nir Orion (2)
Porto University, Portugal (1); Weizmann Institute of Science, Israel (2)

Geoethics emerged as the discipline that studies and reflects upon the values that underpin appropriate human behaviors and practices, whenever humans interact with the Earth. The foundations of geoethics are traced back to three main elements: the importance of geological culture as an essential part of the geoscientist’s background, the concept of responsibility (individual and social), and the definition of an ethical criterion...

Postnatal growth rates of the dwarf hippo Phanourios minor from the Pleistocene of Cyprus

Anneke H. van Heteren & P. Martin Sander
Cyprus, in the Pleistocene, was extremely isolated from a geological and biogeographical point of view. Only two macromammals successfully colonised the island before the Holocene: Elephas cypriotes, approximately 1.4 metres tall at the withers, and Phanourios minor. The latter is the smallest dwarfed hippo ever found; it stood 70 centimetres at the withers and weighed an estimated 200 kilograms, approximately 10% of its mainland ancestor’s weight. The main objective of this study was to determine...
