Re‐examination of the Population, Stratigraphy, and Sequence of Mercurian Basins: Implications for Mercury's Early Impact History and Comparison With the Moon
; ; ; ; ; (Journal of Geophysical Research: Planets, 2020-08-11)
Mercury has one of the best‐preserved impact records in the inner solar system due to the absence of an atmosphere and relatively unmodified ancient surface. However, our knowledge of the early impact record and the nature ... -
Rheological and Mechanical Layering of the Crust Underneath Thumbprint Terrains in Arcadia Planitia, Mars
; ; ; (Journal of Geophysical Research: Planets, 2021-11-10)
In the area of Arcadia Planitia in the Northern hemisphere of Mars, mounds indicating fluid and sediment emissions have been already recognized. Here, we show that through fractal and fracture‐spacing analyses of a large ... -
Rheological change and degassing during a trachytic Vulcanian eruption at Kilian Volcano, Chaîne des Puys, France
; ; ; ; ; ; ; ; ; ; (Bulletin of Volcanology, 2020-11-20)
Magma ascent during silicic dome-forming eruptions is characterized by significant changes in magma viscosity, permeability, and gas overpressure in the conduit. These changes depend on a set of parameters such as ascent ... -
Rheology Dependent on the Distance to the Propagating Thrust Tip—(Ultra‐)Mylonites and Pseudotachylytes of the Silvretta Basal Thrust
; ; (Tectonics, 2023-10-04)
Abstract To evaluate how the presence of pseudotachylytes affects the strength of crustal rocks, ...

Rheology of melts from the colli albani volcanic district (Italy): a case study
; ; (Contributions to Mineralogy and Petrology, 2020-08-14)
In this study the first viscosity measurements in the glass transition range of melts from highly explosive large-volume eruptions from the Colli Albani Volcanic District (CAVD) are presented. The magmas are ultrapotassic, ... -
Rhine flood stories: Spatio‐temporal analysis of historic and projected flood genesis in the Rhine River basin
; ; ; (Hydrological Processes, 2023-06-13)
Abstract The genesis of floods in large river basins often is complex. Streamflow originating ...

Rhine loess at Schwalbenberg II — MIS 4 and 3
(E&G – Quaternary Science Journal; Vol.61, No. 1)
Die Lokalität Schwalbenberg bei Remagen am Mittelrhein erschließt ein sehr vollständiges Profil durch den letztglazialen Löss mit drei Großgliedern. Gut gegliedert sind der Löss der Keldach-Formation (Früh-Weichsel/Würm ... -
Rhizobien in der Pflanzenmikrobiota
(Biologie in unserer Zeit, 2019)Für das Wachstum und Überleben der Pflanze im Boden ist ihre Mikrobiota von maßgeblicher Bedeutung. Pflanzen-Mikrobiota-Interaktionen können unter Laborbedingungen durch definierte Gemeinschaften von Kommensalen nachgestellt ... -
Rhizosphere hydrophobicity: A positive trait in the competition for water.
(PloS one, 2017)The ability to acquire water from the soil is a major driver in interspecific plant competition and it depends on several root functional traits. One of these traits is the excretion of gel-like compounds (mucilage) that ... -
Rimpau’sche Moordammkulturen in Brandenburg
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 33; 2003)Summary: In some fen areas in Brandenburg, the landscape element is marked by narrow grassland areas which are separated from each other at regular intervals by ditches accompanied by trees and bushes. These structures, ... -
Rinikerfeld Palaeolake (Northern Switzerland) – a sedimentary archive of landscape and climate change during the penultimate glacial cycle
; ; ; ; ; ; ; ; (Journal of Quaternary Science, 2022-08-16)
While timing and ice extent of the last glacial maximum are generally well known, the courses of earlier glaciations have remained poorly constrained, with one of the main reasons being the scarcity of sedimentary archives. ... -
Rinnen an der Basis des glaziären Pleistozäns in Schleswig—Holstein
(E&G – Quaternary Science Journal; Vol.29, No. 1)Nach Bohrungsauswertung wird der präquartäre Untergrund und die Basis des glaziären Pleistozäns in Schleswig-Holstein dargestellt. Die Basis des Pleistozäns zeigt Hochgebiete und Rinnensysteme, deren Verlauf weitgehend ... -
Riparian Microtopography Affects Event‐Driven Stream DOC Concentrations and DOM Quality in a Forested Headwater Catchment
; ; ; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2022-12-21)
The transport of dissolved organic carbon (DOC) from the soils to inland waters plays an important role in the global carbon cycle. Widespread increases in DOC concentrations have been observed in surface waters over the ... -
Risk of extreme high fatalities due to weather and climate hazards and its connection to large-scale climate variability
; (Climatic Change, 2020-09-08)
Weather and climate hazards cause too many fatalities each year. These weather and climate hazards are projected to increase in frequency and intensity due to global warming. Here, we use a disaster database to investigate ... -
Riss or Würm?
(E&G – Quaternary Science Journal; Vol.04-05, No. 1)Die Klimaschwankungen des jüngeren Pleistozäns werden anhand von drei unabhängigen Gruppen von Beobachtungsmaterial besprochen, nämlich von Schwankungen des Meeresspiegels, den Terrassenunterkanten der Themse und den ... -
Rivers in the making; the definition of “Nahr” as a hybrid watercourse based on geoarchaeological evidence from Southwestern Iran
