Geochemical, petrophysical and petrographical dataset of fractured Variscan granites of the Cornubian Batholith, SW United Kingdom
Get PDFOutcrop analogue studies are of high priority as they allow the interpretation of geophysical surveys, minimizing the exploration risk, reliable predictions of reservoir properties and drawing conclusions on expected discharge, before drilling in a cost-wise way. Detailed knowledge of the petrophysical properties and petrographical characteristics of potential reservoir rocks improve the interpretation of forthcoming borehole logging and of fluid flow in different zones. Built datasets yet comprise the development of the necessary input for static and dynamic reservoir model parametrization.
In the framework of EU H2020 funded ‘MEET’ project (‘Multidisciplinary and multi-context demonstration of EGS exploration and Exploitation Techniques and potentials’, grant agreement no:792037) outcrop analogue samples from the Cornubian Batholith, located in SW United Kingdom, were taken from the onshore plutons namely Land’s End, Tregonning-Godolphin, Carnmenellis, Carn Brea, Carn Marth and St. Austell. 47 granitic samples were collected from 23 outcrops representative for fresh, weathered, hydrothermally altered, fractured and faulted granites. From the outcrop samples, 338 cores with different diameters were obtained and the measurements of grain density, bulk density, permeability, porosity, acoustic wave velocity, thermal conductivity, thermal diffusivity, magnetic susceptibility, uniaxial compressive strength, Poisson’s ratio, Young’s modulus, tensile strength, shear strength, cohesion, coefficient of friction and shear modulus were performed on oven-dried cores under ambient temperature and atmospheric pressure in the HydroThermikum laboratory of the Technical University of Darmstadt. Petrographical and geochemical characterization were done for 47 outcrop analogue samples and for the drill cuttings, taken between 3,980 and 5,275 m (measured depth) in UD1; the production well of United Downs Deep Geothermal Power Project, first commercial deep geothermal project of UK, through thin section analysis, X-ray diffraction (XRD) and X-ray fluorescence (XRF).
This dataset presents the geochemical, petrophysical and petrographical properties of Early Permian aged fractured Variscan granite specifically not overprinted by any younger tectonic regime. It forms a basis to other publications, where the results of the aforementioned multiparameter rock characterization are discussed in detail and are used for stochastic regional resource assessment, respectively. It follows the same database structure as PetroPhysical Property Database (P³) of Bär et al. (2020). Each analyzed core is provided with a sample ID according to the naming convention within MEET project as ‘MEETCW001001001’ (Project name - region name - location number - sample number - core number)
HEUREC focus group discussion transcripts
No full textTranscripts of focus group discussions in nine countries of the EURO zone (Finland, Germany, Greece, Lithuania, Latvia, Netherlands, Portugal, Slovakia, and Spain). In each country, three discussions have been conducted between December 2021 and May 2022 in three groups: a) high skilled, b) lower-paid and unemployed persons, c) young adults. Discussions were mostly conducted in domestic language, recorded, transcribed and finally translated into English. While translating, the original meaning and appearance was preserved as much as possible. The final texts were not edited to comply with proficiency of English.1.
Dataset and Analysis Codes for "Gamma decay of the ¹⁵⁴Sm Isovector Giant Dipole Resonance: Smekal-Raman Scattering as a Novel Probe of Nuclear Ground-State Deformation"
No full textThis is the preprocessed raw data and analysis code of the photonuclear experiment on the γ-decay Behavior of the Giant Dipole Resonances of ¹⁵⁴Sm and ¹⁴⁰Ce performed in 2021 at the High Intensity γ-ray Source (HIγS) located at the Triangle Universities Nuclear Laboratory (TUNL), Durham, NC, USA by the Technische Universität Darmstadt and TUNL collaboration.
It is published at TUdatalib, TU Darmstadt's institutional repository for all research data generated or worked with at TU Darmstadt (https://tudatalib.ulb.tu-darmstadt.de).
The data forms the basis of the doctoral studies of Jörn Kleemann (https://orcid.org/0000-0003-2596-3762) under the supervision of Prof. Norbert Pietralla (https://orcid.org/0000-0002-4797-3032) at the Technische Universität Darmstadt, Germany and was mainly analyzed by him.
The resulting dissertation (J. Kleemann, "Probing the Giant Dipole Resonance Using Nuclear Resonance Fluorescence", Dissertation, Technische Universität Darmstadt, Darmstadt (2024)) is published with TUprints, the e-publishing-service of TU Darmstadt, and is openly accessible at https://tuprints.ulb.tu-darmstadt.de/27008 and https://doi.org/10.26083/tuprints-00027008 .
Furthermore, a paper on part of the results was accepted for publication in Physical Review Letters (J. Kleemann et al., "Gamma decay of the ¹⁵⁴Sm Isovector Giant Dipole Resonance: Smekal-Raman Scattering as a Novel Probe of Nuclear Ground-State Deformation", Phys. Rev. Lett., to be published (2025)), with the preprint already being available at https://arxiv.org/abs/2406.19695 .
This data publication is directly related to both the dissertation and the peer-reviewed publication and allows for the full reproduction of the analysis and results presented in these works and the creation of all figures contained in them.1.
