Hydrochemical analysis thermal water Neustadt-Glewe, Germany
Hehn, Vera | Iannotta, Joy
2022
The main objective of the work package 2 of the REFLECT project is to characterise relevant fluid properties and their reactions for saline fluids (type C). One of the specific goals was to collect fluid samples from several saline fluids from geothermal sites across Europe, determine their...
Frequency-dependent quality factors of S-coda waves from active ultrasonic transmission measurements in the STIMTEC project, URL Reiche Zeche, Germany
Blanke, Aglaja | Boese, Carolin M.
2022
Mean S-wave coda quality factors (mean-Qc) were estimated from active ultrasonic transmission (UT) measurements acquired during the STIMTEC project in the URL Reiche Zeche (Saxony, Germany). We used S-coda waves of 88 selected UT measurements carried out in 3 differently oriented boreholes...
Ultrasonic transmission measurements from injection borehole and vertical validation boreholes from the STIMTEC experiment, Reiche Zeche Mine, Freiberg (Saxony, Germany)
Boese, Carolin M. | Kwiatek, Grzegorz | Fischer, Thomas | Plenkers, Katrin | Starke, Juliane | Blümle, Felix | Dresen, Georg | Janssen, Christoph
2021
Between early 2018 and late 2019 the STIMTEC hydraulic stimulation experiment was performed at ca.~130 m below surface at the Reiche Zeche underground research laboratory in Freiberg, Saxony/Germany. The project aimed at gaining insight into the creation and growth of fractures in anisotropic...
Experimental data of indirect Tensile, Uniaxial Compressive and Triaxial Compressive tests on Odenwald Granodiorite samples
Muhl, Lena | Blöcher, Guido | Kluge, Christian | Sass, Ingo
2022
An experimental investigation was implemented to explore the mechanical parameters of the Odenwald reservoir granitoids. The specimen within this research project was the Odenwald Granodiorite (ODG) which was extracted from the quarry on Bergstrasse in Heppenheim, Germany. The study enfolds...
Input and resulting structural and parameterized subsurface data for a geological model of the geothermal research platform Groß Schönebeck (North German Basin)
Norden, Ben | Bauer, Klaus | Krawczyk, Charlotte M.
2022
The dataset presented in this compilation provides the input data used for the geological interpretation and for the model parameterization (Norden et al., 2022) of a 3D seismic survey in the area of the geothermal research platform Groß Schönebeck (carried out in 2017; Krawczyk et al.,...
U-Pb data from cherts (Onverwacht Group) and strain data from conglomerates (Moodies Group) from the southern margin of the Archean Barberton Greenstone Belt, Eswatini
Heubeck, Christoph | Thomsen, Tonny B. | Heredia, Benjamin D. | Zeh, Armin | Balling, Philipp
2022
The southern margin of the Barberton Greenstone Belt in Eswatini limits one of the world’s oldest well-preserved sedimentary and volcanic sequences, 3.57 to 3.2 Ga old. In a segment along that margin, older mafic and ultramafic volcanic rocks were thrust over the youngest strata (quartz-rich...
Whole-rock geochemistry of rock units from the Pfitscher Joch area, Western Tauern Window
Franz, Gerhard | Berryman, Eleanor | Kutzschbach, Martin | Meixner, Anette | Kasemann, Simone | Lucassen, Friedrich | Loges, Anselm | Schultze, Dina
2021
In the Western Tauern Window, Zillertal Alps (Austria/Italy), metasediments of a Mesozoic intra-montane basin ("Pfitsch-Mörchner basin"; Veselá and Lammerer, 2008) are exposed. The (me-ta)sediments were deposited on a Variscan basement, which comprises different types of meta-granitoids and...
A global database of radiogenic Nd and Sr isotopes in marine and terrestrial samples (V. 2.0)
Blanchet, Cécile L.
2019
The database presented here contains radiogenic neodymium and strontium isotope ratios measured on both terrestrial and marine sediments. It was compiled to help assessing sediment provenance and transport processes for various time intervals. This can be achieved by either mapping sediment...
Deep seismic reflection profile DEKORP 1986-2N across the eastern Rhenish Massif and the Muensterland Basin, Northwest Germany
Stiller, Manfred | Kaerger, Lauretta | Agafonova, Tatiana | Krawczyk, Charlotte | Oncken, Onno | Weber, Michael | Former DEKORP Project Leaders | Former DEKORP Research Group | Former DEKORP Processing Centre
2021
The profile 2N was recorded in 1986 as part of the DEKORP project, the German deep seismic reflection program. The seismic survey of the ca. 220 km long line 2N was conducted to investigate the deep crustal structure of the eastern Rhenish Massif and the Muensterland Basin with high-fold...
Fluid injection experiments on critically stressed sawcut faults in low-permeability granite samples
Yinlin, Ji | Wang, Lei | Hofmann, Hannes | Kwiatek, Grzegorz | Dresen, Georg
2022
Earthquakes associated with fluid injection in various geo-energy settings, such as shale gas and deep geothermal energy, have shelved many projects with great potential. However, the injection-rate dependence of earthquake nucleation length, i.e., the slowly slipping (creeping) fault length in...
