Experimental Deformation of Opalinus Clay at Elevated Temperature and Pressure Conditions: Mechanical Properties and the Influence of Rock Fabric
(
- Rock Mechanics and Rock Engineering
, 2021-05-11)
The mechanical behavior of the sandy facies of Opalinus Clay (OPA) was investigated in 42 triaxial tests performed on dry samples at unconsolidated, undrained conditions at confining pressures (pc) of 50–100 MPa, temperatures ...
Experimental study and numerical modeling of the thermo-hydro-mechanical processes in soil freezing with different frost penetration directions
(
- Acta Geotechnica
, 2021-04-28)
This research work presents an experimental and numerical study of the coupled thermo-hydro-mechanical (THM) processes that occur during soil freezing. With focusing on the artificial ground freezing (AGF) technology, a ...
Cenozoic Proxy Constraints on Earth System Sensitivity to Greenhouse Gases
(
- Paleoceanography and Paleoclimatology
, 2022-12-08)
The long‐term extent of the Earth system response to anthropogenic interference remains uncertain. However, the geologic record offers insights into this problem as Earth has previously cycled between warm and cold intervals ...
Thermo‐Kinematic Evolution of the Eastern European Alps Along the TRANSALP Transect
(
- Tectonics
, 2023-04-12)
The eastern European Alps are shaped by the indentation of Adria into Europe. Recent tomography, depicting detached slab fragments, has been interpreted as evidence of continuous southward subduction of European lithosphere, ...
Fluvial and permafrost history of the lower Lena River, north‐eastern Siberia, over late Quaternary time
(
- Sedimentology
, 2022-09-29)
Arctic warming and permafrost thaw visibly expose changes in the landscape of the Lena River delta, the largest Arctic delta. Determining the past and modern river regime of thick deltaic deposits shaping the Lena River ...
North Atlantic Drift Sediments Constrain Eocene Tidal Dissipation and the Evolution of the Earth‐Moon System
(
- Paleoceanography and Paleoclimatology
, 2023-02-09)
Cyclostratigraphy and astrochronology are now at the forefront of geologic timekeeping. While this technique heavily relies on the accuracy of astronomical calculations, solar system chaos limits how far back astronomical ...
Paleo‐Hydrogeological Modeling to Understand Present‐Day Groundwater Salinities in a Low‐Lying Coastal Groundwater System (Northwestern Germany)
(
- Water Resources Research
, 2023-04-14)
Groundwater abstraction and drainage are considered to be the main drivers for the salinization of low‐lying coastal groundwater systems, while the role of past boundary conditions is less clear. In this study, 3‐D ...
Release characteristics of overpressurised gas from complex vents: implications for volcanic hazards
(
- Bulletin of Volcanology
, 2020-10-02)
Many explosive volcanic eruptions produce underexpanded starting gas-particle jets. The dynamics of the accompanying pyroclast ejection can be affected by several parameters, including magma texture, gas overpressure, ...
Hydrogeologische Herkunft und geothermisches Potenzial der Thermalquellen von Hintertux, ÖsterreichHydrogeological genesis and geothermal potential of the thermal springs of Hintertux, Austria
(
- Grundwasser
, 2020-03-25)
Europas höchste Thermalquellen in Hintertux, Tirol, sind bis zu 22,5 °C warm und werden zu etwa 30 % genutzt. Bisher lag kein detailliertes konzeptionelles Modell vor, das alle Besonderheiten der Anomalie gemeinsam erklärt ...
Hydrothermal eruption dynamics reflecting vertical variations in host rock geology and geothermal alteration, Champagne Pool, Wai-o-tapu, New Zealand
(
- Bulletin of Volcanology
, 2020-11-14)
Hydrothermal eruptions are characterised by violent explosions ejecting steam, water, mud, and rock. They pose a risk to tourism and the operation of power plants in geothermal areas around the world. Large events with a ...
