2024

This report summarizes the measurements carried out by the GFZ Potsdam on the boreholes Gt S 6/17 and Gt S 7/20 in Schwerin (Mecklenburg-Western Pomerania). The first part of the report describes the borehole measurements of the unperturbed temperature profiles. The second part describes the...

Experimental adsorption parameters of boron isotopes on clay minerals

Ring, Simon J. | Henehan, Michael J. | Blukis, Roberts | von Blanckenburg, Friedhelm

2024

Adsorption and isotopic fractionation of boron on clastic sediment is one process responsible for the heavy boron isotopic composition of the modern ocean. However, the mechanism by which boron complexes to the surface of clay minerals and the cause of its isotopic fractionation are still...

2024

In autumn 2022, an expedition to Tanzania was undertaken within the framework of the research project “CRM-geothermal” and Scintific Priority Program (SPP) 2238 “Dynamics of Ore Metal Enrichment”. Within „CRM-geothermal“ we are looking for an environmentally friendly co-production of critical...

Ultrasonic transmission measurements from seven boreholes from the STIMTEC-X experiment, Reiche Zeche Mine, Freiberg (Saxony, Germany)

Boese, Carolin M. | Kwiatek, Grzegorz | Fischer, Thomas | Plenkers, Katrin | Dresen, Georg

2023

In 2020 and 2021 the STIMTEC-X hydraulic stimulation experiment was performed at ca.~130 m below surface at the Reiche Zeche underground research laboratory in Freiberg, Saxony/Germany. The project temporally followed the STIMTEC experiment at the same site and aimed at understanding the stress...
