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 ... -
Strategies for Simplifying Reactive Transport Models: A Bayesian Model Comparison
(Water Resources Research, 2020-11-22)For simulating reactive transport on aquifer scale, various modeling approaches have been proposed. They vary considerably in their computational demands and in the amount of data needed for their calibration. Typically, ... -
Stratigraphic reconstruction of the Víti breccia at Krafla volcano (Iceland): insights into pre-eruptive conditions priming explosive eruptions in geothermal areas
(Bulletin of Volcanology, 2021-11-02)Krafla central volcano in Iceland has experienced numerous basaltic fissure eruptions through its history, the most recent examples being the Mývatn (1724‒1729) and Krafla Fires (1975–1984). The Mývatn Fires opened with a ... -
Structural characteristics of the halite fabric type ‘Kristallbrocken’ from the Zechstein Basin with regard to its development
(International Journal of Earth SciencesInternational Journal of Earth Sciences, 2008)The Kristallbrocken are a characteristic centimetre- to decimetre-sized, laminated halite fabric type occurring in the Stassfurt Formation in the Zechstein Basin. Up to now, the nature of the Kristallbrocken, i.e. if they ... -
Structural contacts in subduction complexes and their tectonic significance: the Late Palaeozoic coastal accretionary wedge of central Chile
(Journal of the Geological Society, 2007)Understanding the contact between the very low-grade metagreywacke of the Eastern Series and high-pressure metamorphosed schist of the Western Series in the Late Palaeozoic accretionary wedge of central Chile is fundamental ... -
Structural controls on the hydrogeological functioning of a floodplain
(Hydrogeology Journal, 2020-08-22)Floodplains are often conceptualized as homogeneous sediment bodies which connect streams with their respective catchment and buffer agricultural inputs. This has led to a general bias within the hydrological community ... -
Structural Elucidation of α-Cyclodextrin-Succinic Acid Pseudo Dodecahydrate: Expanding the Packing Types of α-Cyclodextrin Inclusion Complexes
(Crystals, 2015)This paper reports a new packing type of -cyclodextrin inclusion complexes, obtained here with succinic acid under low-temperature crystallization conditions. The structure of the 1:1 complex is characterized by heavy ... -
Structural Evolution at the Northeast North German Basin Margin: From Initial Triassic Salt Movement to Late Cretaceous‐Cenozoic Remobilization
(Tectonics, 2020-07-14)In this study, we investigate the regional tectonic impact on salt movement at the northeastern margin of the intracontinental North German Basin. We discuss the evolution of salt pillows in the Bay of Mecklenburg in the ... -
Structural style and neotectonic activity along the Harz Boundary Fault, northern Germany: a multimethod approach integrating geophysics, outcrop data and numerical simulations
(International Journal of Earth Sciences, 2020-05-30)We present new evidence for neotectonic activity along the Harz Boundary Fault, a Cretaceous reverse fault that represents a key structure in northern Germany. For the fault analysis, we use a multimethod approach, integrating ... -
„Strukturelle Evolution“ der Staatlichen Geologie in Neubrandenburg – „Öffnung“ und „Schließung“ aus Verwaltungs-tektonischer Sicht
(Neubrandenburger Geologische Beiträge, 2012-04-17)Rede des Leiters des Geologischen Dienstes von Mecklenburg-Vorpommern, Prof. Dr. habil. Ralf-Otto Niedermeyer, im Rahmen des Abschluss-Kolloquiums am 24. November 2009 anlässlich der Schließung der Außenstelle (Geologisches ... -
Subaqueous conglomerates above pre-LGM basal till: Another element of the ‘classic’ interglacial mountain-flank succession (Hötting Breccia Auct.) north of Innsbruck, Austria
(E&G – Quaternary Science Journal; Vol.65)The “Hötting Breccia” near Innsbruck is a classic interglacial mountain-flank succession mainly comprising lithified alluvial fans and scree slopes. Directly NW of Innsbruck, a pre-LGM (Riss?) basal till >20 m in thickness ... -
Subduction Reversal in a Divergent Double Subduction Zone Drives the Exhumation of Southern Qiangtang Blueschist‐Bearing Mélange, Central Tibet
(Tectonics, 2020-04-04)(Ultra) high‐pressure (HP) rocks can be exhumed rapidly by subduction reversal or divergent plate motion. Recent studies show that subduction reversal can in particular occur in a divergent double subduction zone when the ... -
Subgrain boundaries in Antarctic ice quantified by X-ray Laue diffraction
(Journal of Glaciology, 2011)Ice in polar ice sheets undergoes deformation during its flow towards the coast. Deformation and recrystallization microstructures such as subgrain boundaries can be observed and recorded using high-resolution light ... -
Subsurface Moisture Regulates Himalayan Groundwater Storage and Discharge
(AGU Advances, 2021-05-18)Through the release of groundwater, most mountain rivers run year‐round despite their small catchments and sporadic precipitation. This makes mountain ranges important sources of reliable freshwater for downstream populations ... -
Suitability of terrestrial Lidar and digital photogrammetry for surveying and analysis of fold structures
(Proceedings Volume, 2016-09-23)Quantitative fold structure analyses at different scales are essential for deducing deformation mechanisms and the reconstruction of the deformation history of orogens. However, not only the field surveying of fold structures, ... -
Surface velocity fields of active rock glaciers and ice‐debris complexes in the Central Andes of Argentina
(Earth Surface Processes and Landforms, 2020-12-30)Rock glaciers and transitional ice‐debris complexes predominate the Central Andean landform assemblage, yet regional studies on their state of activity and their kinematics remain sparse. Here we utilize the national glacier ... -
Sustainability impact assessment of peatland-use scenarios: Confronting land use supply with demand
(Ecosystem Services, 2017)Sustainable development of land use is determined by changes of the regional supply of Land Use Functions (LUFs) and the demand of future societal land use claims. LUFs are based on the ecosystem services concept, but ... -
