The Bushveld Drilling Project (BVDP) of the International Scientific Drilling Program (ICDP) has obtained drill cores through almost the entire 8000 meter-thickness of the Rustenburg Layered Series of the Bushveld Igneous Complex in the South Africa, the largest layered mafic intrusion on...

Digital image correlation data from analogue modeling experiments addressing the role of spreading in gravity-driven salt tectonics

Ge, Zhiyuan | Rosenau, Matthias | Warsitzka, Michael

2020

This data set includes the results of digital image correlation of one experiment 71-009 on gravitational tectonics at passive margins performed at the Helmholtz Laboratory for Tectonic Modelling (HelTec) of the GFZ German Research Centre for Geosciences. The experiment has two model basins A...

Integrated measurements of capillary pressure, electrical resistivity, and elastic wave velocities conducted during sample drainage and imbibition under simulated reservoir conditions.

Kummerow, Juliane | Spangenberg, Erik

2026

Understanding how fluids migrate through underground rock formations is essential for securely storing carbon dioxide ($CO_2$), managing groundwater resources, or cleaning up contaminated soils. A key parameter in this context is the capillary pressure, the pressure difference between two...

Hydrochemical and isotopic dataset for the characterization of fault-bound hydrothermal reservoirs of the Western Bohemian Massif (Germany)

Prause, Simon | Kämpf, Horst | Strauch, Gerhard | Broge, Alena Sophie | Perssen, Ferdinand | Kunze, Christian | Stammeier, Jessica Alexandra | Günther, Kristin | Tonn, Sabine | Görne, Sascha

2026

We compiled a hydrochemical and isotopic dataset for surface water, groundwater and thermal water from the regions of SW Saxony, the Fichtel Mountains and the Central Ore Mountains. The goal of this publication is to create a basis for the characterization of local geothermal reservoirs in...

Lithium, copper, strontium in various geological formations of the Groß Schönebeck well Gt Grsk04/05

Regenspurg, Simona | Thomas, Anika | Stammeier, Jessica A. | Wilke, Franziska D.H. | van Schijndel, Valby

2026

Cutting samples of 23 geological formations from different depths (measured depth, MD) between 1.4 and 4.4 km of the geothermal research well Groß Schönebeck site were analyzed with focus on lithium (Li), copper (Cu), and strontium (Sr). To determine how strong and to which components these...

Enhanced earthquake catalog (2017–February 5, 2023) for the epicentral region of the 2023 Mw 7.8 Kahramanmaraş earthquake, Türkiye

Núñez-Jara, Sebastián | Martínez-Garzón, Patricia | Kwiatek, Grzegorz | Yehuda, Ben-Zion | Dresen, Georg | Becker, Dirk | Cotton, Fabrice | Bohnhoff, Marco

2025

This earthquake catalog was constructed using a combination of artificial intelligence and traditional methods for phase picking, phase association, and earthquake relocation. It covers the period from January 1, 2017, to February 5, 2023—one day prior to the Mw 7.8 earthquake that struck...

Chemical, mineralogical and isotopic characterization of Ca-Mg-Fe carbonates for SIMS microanalysis

Scicchitano, Maria Rosa | Harris, Chris | Luyt, Julie | Pack, Andreas | di Rocco, Tommaso | Vennemann, Torsten | Wilke, Franziska D.H. | Schleicher, Anja M. | Glodny, Johannes | Tait, Kimberly T. | Philippo, Simon

2025

Carbonate minerals of the dolomite-ankerite and magnesite-siderite series are often found in sedimentary basins associated with economically viable ore deposits and as alteration product of Ca-Mg-Fe-silicates in igneous and metamorphic rocks. Analysis of oxygen and carbon isotopes in such...

Results of CO2 flux measurements and seismic catalogue related to the August 2024 eruption at Reykjanes, SW Iceland

Strauch, Bettina | Buyukakpinar, Pinar | Hurley, Maria | Zimmer, Martin | Walter, T.

2025

Here we present data on the spatiotemporal distribution of seismicity and CO2 flux from the highly active Svartsengi–Eldvörp volcanic system (hereafter referred to as Svartsengi) on the Reykjanes Peninsula. Data were collected between July and September 2024. The area is marked by repeated...

Laboratory Investigation of Fracture Behavior and Roughness Evolution in Simulated Hydraulic Shear Stimulation for Enhanced Geothermal Systems (EGS)

Kalantar, Alireza | Hofmann, Hannes | Yinlin, Ji | Blöcher, Guido | Muhl, Lena | Zang, Arno

2025

Enhanced Geothermal Systems (EGS) utilize artificially induced fracture networks to enable fluid circulation and heat extraction from high-temperature, low-permeability geological formations. Unlike conventional hydraulic fracturing in the hydrocarbon industry—which commonly employs proppants...

Hydrogeological characterisation of a Lower Jurassic rock unit at the Mont Terri - I: Data of the Opalinus Clay and the Staffelegg Formation

Bonitz, Marie | Blessing, Michaela | Eichinger, Florian | Fernández, Ana María | Flehoc, Christine | Harrington, Jon | Hostettler, Bernhard | Jaeggi, David | Kampman, Niko | Kemp, Simon | Kühn, Michael | Lahfid, Abdeltif | León, Francisco J. | Lerouge, Catherine | Maubec, Nicolas | Niedermann, Samuel | Nieto, Paula | Ostertag-Henning, Christian | Preisig, Giona | Regard, Vincent | Schleicher, Anja M. | Stammeier, Jessica A. | Strauch, Bettina | Valley, Benoit | Wille, Guillaume | Wiseall, Andrew | Zimmer, Martin | Zwahlen, Carmen

2024

Opalinus Clay is chosen as host rock for the deep geological disposal of nuclear waste in Switzerland and is also being considered in Germany. The underlying Staffelegg Formation comprises potentially water-bearing layers. To investigate the hydrogeological setting of these two formations at...
