A co-ordinated German approach to non-traditional tertiary geoscience (field) education?

Virginia Gail Toy
Johannes Gutenberg-Universität Mainz, Germany

The restrictions in place due to the COVID epidemic have forced us to develop non-traditional solutions to teach field geology in the last few months, such as virtual field excursions, and entirely new safety and hygiene plans. Many of the solutions we have developed should be made into permanent resources that will increase the accessibility of our courses to students and society. Since ~March 2020, similar resources have been developed...

Virtual field trip to Late Jurassic Carbonates of Central Saudi Arabia

Pankaj Khanna, Ahmad Ihsan Ramdani, Gaurav Siddharth Gairola & Volker Vahrenkamp
KAUST, Saudi Arabia

Late Jurassic carbonates of Saudi Arabia contain some of the the world’s most prolific oil-producing strata in super giant reservoirs. Small scale stratigraphic architecture and associated property and flow heterogeneities are poorly resolved in the inter-well scale of hundreds of meters because such heterogeneities are subseismic and beyond penetration of borehole logs. This blindspot leads to oversimplified reservoir models and simulations. However, analogous strata is spectacularly exposed in the outcrops...

Jan-Henrik Kupfernagel , Jan Christopher Hesse, Bastian Welsch , Markus Schedel, Ingo Sass & Lutz Müller
Technische University of Applied Science Ostwestfalen-Lippe, Germany (1); Technical University of Darmstadt, Germany (2)

For several reasons, the inlet temperature of the heat carrier fluid in borehole heat exchangers (BHE) may temporarily fall below the freezing point of water. Consequently, freezing and thawing processes are induced in the grouting material and the surrounding subsoil. However, these processes also influence the transition zonecontact area between pipes and grout as well as the skin zone...

Insights on the evolution of the Himalayas and Tibet from thermomechanical modelling: the role of long-term convergence

Ben S. Knight, Fabio A. Capitanio & Roberto F. Weinberg
Monash University, Australia

The collision of India and Eurasia has resulted in a broad range of structures, from the Himalayan chain to the Tibetan Plateau. The convergence history is characterised by velocities of > 10 cm/yr at collision to current velocities of ~5 cm/yr, of which ~2cm/yr are accommodated at the orogens' front. Our thermomechanical model simulates the collision of India and Eurasia to assess the role of the decrease in velocity, highlighting 4...

Jacob Wächter, Christian Olaf Müller, Alexander Malz & Klaus-Jörg Hartmann
Landesamt für Geologie und Bergwesen Sachsen-Anhalt, Germany

Modelling of subsurface temperatures is based on various approaches, which typically focus on interpolation or numerical simulation procedures. Mostly, they are based on few single measurements and do not take into account the geological structure or lithological and thermal conductivity conditions of the subsurface. Herein, we present a new approach for the parameterization and modelling of subsurface temperatures for areas with sparse available data. We used temperature...

Runjian Chu, Huaichun Wu, Rukai Zhu & Qiang Fang
China University of Geosciences (Beijing), China (1); Research Institute of Petroleum Exploration Development, PetroChina, Beijing, China (2)

The “hothouse” Triassic climate provides a key window to study megamonsoon systems. However, high-quality paleoclimate proxy records are rarely reported from the Tethys realm, where the seasonal meridional migration of the intertropical convergence zone (ITCZ) should be the most remarkable. Here, continuous and well-dated proxy records are used to study monsoon activity in the northeastern Tethys from the...
