Ramgarh, Rajasthan, India: A 10 km diameter complex impact structure
(Meteoritics & Planetary Science, 2020)The Ramgarh structure is a morphological landmark in southeastern Rajasthan, India. Its 200 m high and 3.5–4 km wide annular collar has provoked many hypotheses regarding its origin, including impact. Here, we document ... -

Rare Holocene sediment deposits from Sodmein Playa (Eastern Desert, Egypt)—Stratigraphic assessment and environmental setting
(Geoarchaeology, 2022-11-12)Sodmein Playa is one of the rare Pleistocene open‐air sites in the Eastern Desert of Egypt. Based on the associated stone artefact material, it could be assigned to the Middle Stone Age/Last Interglacial. However, it has ... -
Rates of rockwall slope erosion in the upper Bhagirathi catchment, Garhwal Himalaya
(Earth Surface Processes and Landforms, 2019)Rockwall slope erosion is defined for the upper Bhagirathi catchment using cosmogenic Beryllium-10 (10Be) concentrations in sediment from medial moraines on Gangotri glacier. Beryllium-10 concentrations range from 1.1 ± ... -
Raumordnungspolitik als Verdichtung politischer Kräfteverhältnisse
(s u b \ u r b a n . zeitschrift für kritische stadtforschung, 2017)Am Beispiel der Raumordnungspolitik der Bundesrepublik Deutschland der 1970er-Jahre wird im Beitrag mithilfe der historisch-materialistischen Politikanalyse die politische Verdichtung der Kräfteverhältnisse bezüglich ... -
Räumliche ingenieurgeologische Modellierung im Stadtgebiet von Göttingen
(2008)In städtischen Räumen erhobene geologische, hydrogeologische und ingenieurgeologische Punkt- und Flächendaten werden meist dezentral verwaltet. Erst durch das Überführen der unterschiedlichen Punkt- und Flächendaten in ein ... -
Reassessing evidence of Moon–Earth dynamics from tidal bundles at 3.2 Ga (Moodies Group, Barberton Greenstone Belt, South Africa)
(Sedimentology, 2022-04-05)Past orbital parameters of the Moon are difficult to reconstruct from geological records because relevant data sets of tidal strata are scarce or incomplete. The sole Archean data point is from the Moodies Group (ca 3.22 Ga) ... -
Recent advances in the study of Arctic submarine permafrost
(Permafrost and Periglacial Processes, 2020)Submarine permafrost is perennially cryotic earth material that lies offshore. Most submarine permafrost is relict terrestrial permafrost beneath the Arctic shelf seas, was inundated after the last glaciation, and has been ... -
Recent developments in neutron imaging with applications for porous media research
(Solid Earth, 2016)Computed tomography has become a routine method for probing processes in porous media, and the use of neutron imaging is especially suited to the study of the dynamics of hydrogenous fluids, and of fluids in a ... -
Reconstructing Depositional Rates and Their Effect on Paleoenvironmental Proxies: The Case of the Lau Carbon Isotope Excursion in Gotland, Sweden
(Paleoceanography and Paleoclimatology, 2020-12-19)Variations in depositional rates affect the temporal depositional resolutions of proxies used for paleoenvironmental reconstructions; for example, condensation can make reconstructed environmental changes appear very abrupt. ... -
Redetermination and invariom refinement of 1-cyclopropyl-6-fluoro-4-oxo-7-(piperazin-4-ium-1-yl)-1,4-dihydroquinoline-3-carboxylate hexahydrate at 120 K
(Acta Crystallographica Section E Structure Reports Online, 2008)The structure of the title compound, C17H18FN3O3 6H2O, has been redetermined at 120 K. An invariom refinement, a structural refinement using aspherical scattering factors from theoretically predicted multipole population ... -

Relative quantification of wind erosion in argan woodlands in the Souss Basin, Morocco
(Earth Surface Processes and Landforms, 2020)The endemic argan woodlands cover large parts of South Morocco and create a characteristic landscape with areas of sparsely vegetated and bare soil surfaces between single trees. This unique ecosystem has been under extensive ... -
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, ... -

Relict high-Andean ecosystems challenge our concepts of naturalness and human impact
(Scientific Reports, 2017)What would current ecosystems be like without the impact of mankind? This question, which is critical for ecosystem management, has long remained unanswered due to a lack of present-day data from truly undisturbed ecosystems. ... -
Repeatedly Evolved Host-Specific Ectosymbioses between Sulfur-Oxidizing Bacteria and Amphipods Living in a Cave Ecosystem
(PLoS ONE, 2012-11-29)Ectosymbioses between invertebrates and sulfur-oxidizing bacteria are widespread in sulfidic marine environments and have evolved independently in several invertebrate phyla. The first example from a freshwater habitat, ... -
Representation of water abstraction from a karst conduit with numerical discrete-continuum models
(Hydrology and Earth System Sciences, 2014)Karst aquifers are characterized by highly conductive conduit flow paths embedded in a less conductive fissured and fractured matrix, resulting in strong permeability contrasts with structured heterogeneity and ... -
Rescuing Fe0 remediation research from its systemic flaws
(Research and Review Insights, 2017)The well-accepted assumption of metallic iron (Fe0) acting as electron donor for environmental remediation has created an unstable domain of knowledge for the past 23 years. This assumption is discouraging some outstanding ...
