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...

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

Hohf, Michael | Trumbull, Robert

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...

Properties of rock analogue materials used for Foamquake: a novel seismotectonic analog model mimicking the megathrust seismic cycle at RomaTre University (Italy)

Mastella, Giacomo | Corbi, Fabio | Funiciello, Francesca | Rosenau, Matthias | Rudolf, Michael | Kosari, Ehsan

2021

This dataset provides friction and elasticity data from ring shear and axial tests, respectively, on rock analogue materials used at the University Roma Tre (Rome, IT) in “Foamquake”, a novel seismotectonic analog model mimicking the megathrust seismic cycle (Mastella et al., under review). Two...

Geochemistry of sediments from Arctic thermokarst lakes and lagoons on the Bykovsky Peninsula, Siberia

Yang, Sizhong | Anthony, Sara E. | Jenrich, Maren | In ‘t Zandt, Michiel H. | Strauss, Jens | Overduin, Pier Paul | Grosse, Guido | Angelopoulos, Michael | Biskaborn, Boris K. | Grigoriev, Mikhail N | Wagner, Dirk | Knoblauch, Christian | Jaeschke, Andrea | Rethemeyer, Janet | Kallmeyer, Jens | Liebner, Susanne

2022

In coastal Arctic permafrost regions, thermokarst lagoons represent the transition state from a freshwater lacustrine to a marine environment, and receive little attention regarding their role for greenhouse gas production and release. The geochemical features of a thermokarst lagoon were...

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...

Organochemical characterization of the mineralized Kupferschiefer in Spremberg, East Germany: Compositional and isotope data on hydrocarbons, biomarker and NSO compounds

Poetz, Stefanie | Liu, Yang | Magnall, Joseph M. | Vieth-Hillebrand, Andrea | Yang, Shengyu | Göthel, Michael | Gleeson, Sarah A. | Schulz, Hans-Martin | Karger, Cornelia | Noack, Doreen | Günther, Kristin | Kaminsky, Anke | Rothe, Heike

2022

Organic matter (OM) is known to be an important reductant in sediment-hosted base metal deposits like the European Kupferschiefer. However, the precise nature of interactions between OM and hydrothermal fluids are still debated as well as how the interconnected reactions develop over geological...

Spectral decomposition results for the SCEC-Community Stress Drop Validation study

Bindi, Dino | Spallarossa, Daniele | Picozzi, Matteo | Oth, Adrien | Morasca, Paola | Mayeda, Kevin

2023

The Community Stress Drop Validation Study has been organized as a technical activity group (TAG) of SCEC (Southern California Earthquake Center) with the aim of investigating the source parameters of the 2019 Ridgecrest seismic sequence in California. Information about the stress drop TAG...
