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...

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 | Bauer, Klaus

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.,...

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...

Chemical (EPMA) and boron isotope (SIMS) analyses on tourmaline breccias from the Río Blanco-Los Bronces porphyry copper district, Chile

Hohf, Michael | Trumbull, Robert B.

2022

Tourmaline-cemented magmatic-hydrothermal breccias are a major host to sulphide mineralization in the supergiant Río Blanco–Los Bronces (RB–LB) porphyry Cu-Mo district in central Chile. We made an extensive study of the chemical and boron isotopic composition of tourmaline from this district to...

Major and trace element analysis of Ca-Mg-carbonates and carbonate melt at 6 and 9 GPa

Sieber, Melanie J. | Wilke, Franziska D. H. | Appel, Oona | Oelze, Marcus | Koch-Müller, Monika

2022

The melting relations of the CaCO3 MgCO3 system are investigated and trace element partition coefficient of Li, Na, K, Mn, Fe, Sr, Ba, Pb, Nb, Y and rare earth elements (REEs) between carbonates (Mg-calcite, Ca-magnesite) and dolomitic melt are established from high pressure (6 and 9 GPa) and...

Dissolved organic compounds in geothermal fluids used for energy production

Leins, Alessio | Vieth-Hillebrand, Andrea | Bregnard, Danaé | Günther, Kristin | Junier, Pilar | Regenspurg, Simona

2022

This data was collected to write an extensive review on organic compounds in geothermal fluids as part of the REFLECT (Redefining geothermal fluid properties at extreme conditions to optimize future geothermal energy extraction). The data is mainly focussed on geothermal sites were organic...

Reflectance spectra and LIBS data of 16 iron-bearing surface samples from Rammelsberg – a non-ferrous metal mine in the Harz Mountains near Goslar, Germany

Hildebrand, Constantin | Koellner, Nicole | Kaestner, Friederike | Koerting, Friederike | Mielke, Christian

2022

This data publication presents data from a solaroptical spectral investigation in the area of the Rammelsberg non-ferrous metal mine in the Harz Mountains near the city of Goslar. The investigation refers to the local communion stone quarry (“Kommunionssteinbruch”) above the former mining area....

3D-CEBS-TTH: transient thermohydraulic model of the Central European Basin System (CEBS)

Frick, Maximilian | Cacace, Mauro | Klemann, Volker | Tarasov, Lev | Scheck-Wenderoth, Magdalena

2021

We provide a single file (exodus II format) that contains all results of the modeling efforts of the associated paper. This encompasses all structural information as well as the pore pressure, temperature, and fluid velocity distribution through time. We also supply all files necessary to rerun...

Spatial and temporal changes of pressure and CO2 concentration in isolated borehole sections in the marginal area of a cavernous structure - an underground in-situ study in rock salts

Strauch, Bettina | Zimmer, Martin | Kujawa, Christian | Zirkler, Axel

2022

We present a dataset of in-situ measurements in the marginal area of a CO2- and brine-rich cavernous structure in an underground salt mine. The data were collected within the framework of the BMBF-project ProSalz. One aim was to reveal the sources and dynamics of fluid movement as well as...
