Quantitative mineralogy, mineral chemistry and microtex-tural data on the UG2 chromitite intruded by iron-rich ul-tramafic pegmatite (IRUP) at the Thaba Mine, northwest-ern Bushveld Complex, South Africa

Zhou, Haoyang | Appelt, Oona | Tjallingii, Rik | Bachmann, Kai | Trumbull, Robert B.

2023

Discordant iron-rich ultramafic pegmatites (IRUPs) intersect the UG2 chromitite at many places in the Bushveld Complex but the effects on ore grade and mineralogy have rarely been studied in detail. We investigated a drillcore profile through the UG2 layer affected by IRUP intrusions at...

Acoustic Emission and Seismic moment tensor catalogs associated with triaxial stick-slip experiments performed on Westerly Granite samples

Kwiatek, Grzegorz | Goebel, Thomas

2024

The dataset contains source parameters of acoustic emission (AE) events recorded during triaxial friction (stick-slip) experiments performed on the Westerly Granite sample WgN05. In addition we provide raw waveform data of AE events recorded in triggered mode with a network of 16 AE sensors....

Results of Experimental Simulations on Hydrogen Migration through Potential Storage Rocks

Strauch, Bettina | Pilz, Peter | Zimmer, Martin | Kujawa, Christian

2023

Data on the diffusivity of hydrogen through rocks are published here. The studied rocks are related to storage formations, namely rock salt (salt caverns), sandstone (porous aquifer) and mudstone (cap rock). To quantify hydrogen diffusion rates in these rocks, a new experimental set up was...

Comprehensive data set of in-situ hydraulic stimulation experiments for geothermal purposes at the Äspö Hard Rock Laboratory (Sweden)

Zang, Arno | Niemz, Peter | von Specht, Sebastian | Zimmermann, Günther | Milkereit, Claus | Plenkers, Katrin | Klee, Gerd

2023

This data set contains measurements of an underground hydraulic fracture experiment at Äspö Hard Rock Laboratory in May and June 2015. The experiment tested various injection schemes for rock fracture stimulation and monitored the resulting seismicity. The primary purpose of the experiment is...

Dissolved organic compounds in geothermal fluids used for energy production – part II

Leins, Alessio | Vieth-Hillebrand, Andrea | Günther, Kristin | Regenspurg, Simona

2023

This dataset comprises 47 fluid samples from 11 geothermal sites (Germany, Austria, Iceland, Turkey, Netherlands, Belgium, French West Indies). The samples were collected within the REFLECT project (Redefining geothermal properties at extreme conditions to optimize future geothermal energy...

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...

Hydrochemichal analysis thermal water Gross Schoenebeck, 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...
