The exploration well GeoLaB-1 will be drilled in February 2025 into the Tromm pluton Odenwald (SW Germany) with a maximum depth of 500 m. An only 20-30 cm thin veneer Quaternary sediments is expected on top few m weathered granite, followed by massive granites and quartz-monzonites until final depth. drilling plan involves full coring comprehensive logging program pluton. Drilling accompanied 2D-seismic, gravimetric, geoelectric, magnetic surveys. cores provide basic information about...
The Chattian-Oligocene interval of the Northern Upper Rhine Graben (URG) is characterized by a complex stratigraphic and structural framework influenced several phases tectonic activity variations crustal stress fields. deposition fluviatile-lacustrine Niederrödern Formation coincides with major Chattian regression phase overlaying unconformably brackish-marine uniform Grey Bed Series (Froidefontaine Formation). colorful marls hosting sand layers lenses that were partly exploited...
A climate-neutral transformation of the heating sector is essential for energy transition, and geothermal offers substantial potential to achieve climate protection targets. While importance transition widely recognized, deep projects often face challenges resulting from unfavorable public perception. Induced seismicity, in particular, raises concerns significantly influences social acceptance. Several factors contribute these concerns, including inadequate or poorly communicated information...
Abstract The essentially non‐magmatic continental rift system of the Upper Rhine Graben (URG) is segmented and characterized by intra‐rift sub‐basins that exhibit NE to NW trends suggesting complex basin development during rifting. Structural modeling analyses an about 40 km 2 3D seismic survey from northern part central URG segment show deep rooted NNE‐striking faults controlling early, syn‐rift 1, extensional evolution 47 Ma 27 Ma. change in stress field at subsequent reactivation these...
Abstract Springs located at the historical sites of Wadi Araba (Eastern Desert Egypt) and emerging from escarpments Northern Southern Galala Plateaus were investigated. A combination methods, including hydrochemistry, stable radioisotope composition, structural analyses based on satellite data, provided information about structure subsurface derived groundwater flow paths. Satellite images reveal karst features within northern plateau, e.g. conical landforms. Karstic caves documented along...
We report on the successful integration of a low equivalent oxide thickness (EOT) negative capacitance (NC) gate stack – 1.8 nm ferroelectric-antiferroelectric (FE-AFE) HfO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> -ZrO superlattice (HZH) [1] into 90 CMOS R&D technology, following self-aligned, replacement process. The integrated oxides show an effective 7.5 Å both p - and n-SOI MOSFETs. This amounts to 2Å EOT lowering compared...
Abstract Porous and fractured aquifers exist in the area of Hurghada, Eastern Desert Egypt, whose recharge processes through common flash floods are not identified. Hydrochemical parameters, stable isotopes 18 O, 2 H tritium floodwater groundwater were applied subject to study. Additionally, He investigated deep wells faulted zone at Abu Shaar Plateau. 3 activity all sampled points lies below detection limit excluding a recent component groundwater. However, hydrochemical ratios isotope...
The campus of the Karlsruhe Institute Technology (KIT) contains several waste heat streams. In an effort to reduce greenhouse gas emissions by optimizing thermal power consumption on campus, researchers at KIT are proposing a ‘DeepStor’ project, which will sequester from these streams in underground reservoir during summer months, when is not required. stored then be reproduced winter, campus’s demand much higher. This paper preliminary geochemical risk assessment for operation this...
Abstract. Evaluating uncertainties of geological features on temperature and pressure changes in reservoir’s fluids are crucial for a safe sustainable operation the High-Temperature Aquifer Thermal Energy Storage (HT-ATES). This study uses new automated surface fitting function Python API GMSH (v. 4.11) to model impact arbitrary structural barriers variations roof floor geometries heat storage application. A workflow is developed implement an mesh generation routine varying scenarios that...
