Revisiting afro-alpine Lake Garba Guracha in the Bale Mountains of Ethiopia: rationale, chronology, geochemistry, and paleoenvironmental implications
(
- Journal of Paleolimnology
, 2020-06-30)
Previous paleolimnological studies demonstrated that the sediments of Garba Guracha, situated at 3950 m asl in the afro-alpine zone of the Bale Mountains of Ethiopia, provide a complete Late Glacial and Holocene paleoclimate ...
An automated testing device for continuous measurement of the hysteretic water retention curve of granular media
(
- Acta Geotechnica
, 2020-02-11)
The water retention curve (WRC), representing an important key for the modelling of hydro-mechanical behaviour of unsaturated soils, is still not fully understood, because it originates from microscopic hydraulic and ...
Strain-dependent slope stability
(
- Acta Geotechnica
, 2020-05-09)
The state of equilibrium of a slope is usually interpreted and expressed by safety factors based on calculations with limit equilibrium methods. Different stress states, failure modes and hydraulic conditions in sections ...
Middle and Late Devonian paleogeography of the eastern Anti-Atlas (Morocco)
(
- International Journal of Earth Sciences
, 2021-04-17)
The eastern Anti-Atlas of Morocco represents one of the most completely exposed and perfectly documented biostratigraphic records of the entire Devonian worldwide. Paleogeographically it is clearly differentiated into ...
Multiphase-field modelling of crack propagation in geological materials and porous media with Drucker-Prager plasticity
(
- Computational Geosciences
, 2020-10-22)
A multiphase-field approach for elasto-plastic and anisotropic brittle crack propagation in geological systems consisting of different regions of brittle and ductile materials is presented and employed to computationally ...
Zur Land- und Bodendegradation – ein Rück- und Ausblick deutschland- und weltweit
(2023)
Soils and landscapes are bridges of space and time, as they simultaneously and authentically show essential aspects that were previously separated by time and space (such as cultural and activity-related aspects from past ...
Numerical Modeling of Structurally Controlled Ore Formation in Magmatic‐Hydrothermal Systems
(
- Geochemistry, Geophysics, Geosystems
, 2022-08-11)
Faults and fractures can be permeable pathways for focused fluid flow in structurally controlled ore‐forming hydrothermal systems. However, quantifying their role in fluid flow on the scale of several kilometers with ...
On the Role of Rheological Memory for Convection‐Driven Plate Reorganizations
(
- Geophysical Research Letters
, 2022-09-21)
Understanding the temporal variability of plate tectonics is key to unraveling how mantle convection transports heat, and one critical factor for the formation and evolution of plate boundaries is rheological “memory,” ...
Modeling Lithospheric Thickness Along the Conjugate South Atlantic Passive Margins Implies Asymmetric Rift Initiation
(
- Tectonics
, 2022-09-20)
The lithospheric architecture of passive margins is crucial for understanding the tectonic processes that caused the breakup of Gondwana. We highlight the evolution of the South Atlantic passive margins by a simple thermal ...
Hillslope Sediment Supply Limits Alluvial Valley Width
(
- AGU Advances
, 2022-10-31)
River‐valley morphology preserves information on tectonic and climatic conditions that shape landscapes. Observations suggest that river discharge and valley‐wall lithology are the main controls on valley width. Yet, current ...
