Laboruntersuchungen zur Freisetzung von Unat aus einem Gestein unter oxischen naturnahen Bedingungen
; Sonnefeld, Jürgen; Sauter, Martin (Grundwasser, 2005)
Im Labor wurden verschiedene Größen (pH-Wert, HCO3 --Gehalt, Präsenz von Fe(OH)3) untersucht, von denen angenommen werden konnte, dass sie die umweltrelevante Freisetzung von Uran aus Gesteinen (z.B. Haufwerken, Halden, ... -

Lake Van, Eastern Anatolia, Hydrochemistry and History
(Aquatic GeochemistryAquatic Geochemistry, 2008)Saline, 450-m-deep Lake Van (Eastern Anatolia, Turkey) is, with 576 km3, the third largest closed lake on Earth and its largest soda lake. In 1989 and 1990, we investigated the hydrochemistry of the lake’s water column and ... -
LakeCC: a tool for efficiently identifying lake basins with application to palaeogeographic reconstructions of North America
; ; (Journal of Quaternary Science, 2019)
Along the margins of continental ice sheets, lakes formed in isostatically depressed basins during glacial retreat. Their shorelines and extent are sensitive to the ice margin and the glacial history of the region. Proglacial ... -
Land Surface Temperature Variation Due to Changes in Elevation in Northwest Vietnam
(Climate, 2018)Land surface temperature (LST) is one of the most important variables for applications relating to the physics of land surface processes. LST rapidly changes in both space and time, and knowledge of LST and its spatiotemporal ... -
Large, heterometallic coordination cages based on ditopic metallo-ligands with 3-pyridyl donor groups
(Chem. Sci., 2014)Ditopic N-donor ligands with terminal 4-pyridyl groups are omnipresent in coordination-based selfassembly. The utilization of ligands with 3-pyridyl donor groups is significantly less common, because the intrinsic ... -
Large‐scale mass movements recorded in the sediments of Lake Hallstatt (Austria)–evidence for recurrent natural hazards at a UNESCO World Heritage site
; ; ; ; ; ; ; (Journal of Quaternary Science, 2022-08-28)
The Bronze to Iron Age underground salt mining complex of Hallstatt (Austria) is widely recognised for its cultural importance and wealth of archaeological artefacts. However, while the daily life in the salt mines is ... -
Last Interglacial paleosols with Argic horizons in Upper Austria and Central Russia
(E&G – Quaternary Science Journal; Vol.62)The paleosols of the Last Interglacial are presented in many loess sequences of the European temperate zone by soils with Argic horizon, that are considered to be the pedological response to the bioclimatic conditions of ... -
Late Cretaceous to Miocene tectonic reconstruction of the northwestern Caribbean - regional analysis of Cuban geology
(Univ. Greifswald, 2009)The Caribbean is a geologically complex region with several different plate boundary interactions. Geodynamic reconstructions of the northwestern Caribbean region have been particularly controversial in terms of the number ... -
Late Miocene Exhumation of the Western Cordillera, Ecuador, Driven by Increased Coupling Between the Subducting Carnegie Ridge and the South American Continent
; ; ; ; ; ; (Tectonics, 2023-01-12)
The subduction of bathymetric highs, such as aseismic ridges, leads to far‐reaching changes in the dynamics of subduction zones with increased plate coupling and deformation in the upper plate. Subduction of the submarine ... -
Late Oligocene—Early Miocene shortening in the Thrace Basin, northern Aegean
; ; (International Journal of Earth Sciences, 2021-05-15)
Late Cenozoic was a period of large-scale extension in the Aegean. The extension is mainly recorded in the metamorphic core complexes with little data from the sedimentary sequences. The exception is the Thrace Basin in ... -
Late Palaeozoic red beds elucidate fluvial architectures preserving large woody debris in the seasonal tropics of central Pangaea
; Gaitzsch, Birgit; ; Ehling, Bodo-Carlo; Kleeberg, Reinhard; (Sedimentology, 2020)
Fluvial red beds containing anatomically preserved large woody debris shed new light on seasonally dry biomes of the Pennsylvanian–Permian transition and elucidate the concurrence of river depositional systems and vegetation. ... -
Late Pleistocene to Recent Deformation in the Thick‐Skinned Fold‐and‐Thrust Belt of Northwestern Argentina (Central Calchaquí Valley, 26°S)
; ; ; ; ; ; Aranda‐Viana, R. Germán; (Tectonics, 2020-12-29)
The thick‐skinned fold‐and‐thrust belt on the eastern flank of the Andean Plateau in northwestern Argentina (NWA) is a zone of active contractional deformation characterized by fault‐bounded mountain ranges with no systematic ... -
Late Pleistocene‐Holocene Slip Rates in the Northwestern Zagros Mountains (Kurdistan Region of Iraq) Derived From Luminescence Dating of River Terraces and Structural Modeling
; ; ; ; (Tectonics, 2021-08-23)
A significant amount of the ongoing shortening between the Eurasian and Arabian plates is accommodated within the Zagros Fold‐Thrust Belt. However, the spatial and temporal distribution of active shortening within the belt, ... -
Late Quaternary environmental history of Taylor Valley, southern Victoria Land, Antarctica, reconstructed by a multidisciplinary study of lake sediments
(Univ. Köln, 2009)In the unglaciated areas of Antarctica, lake sediments act as archives of the regional environmental and climatic history. In most cases, the records are restricted to the Holocene. Amongst the few exceptions are lakes in ... -
Late-stage volcano geomorphic evolution of the Pleistocene San Francisco Mountain, Arizona (USA), based on high-resolution DEM analysis and 40Ar/39Ar chronology
(Bulletin of Volcanology, Vol. 72, Nr. 7, p. 833-846, 2010)The cone-building volcanic activity and subsequent erosion of San Francisco Mountain, AZ, USA, were studied by using high-resolution digital elevation model (DEM) analysis and new 40Ar/39Ar dating. By defining remnants or ... -
Lateglacial and Holocene environmental history of the central Kola region, northwestern Russia revealed by a sediment succession from Lake Imandra

Lattice preferred orientation as an indicator of a complex deformation history of rocks
(Textures and microstructures, 1999)The deconvolution of the deformation history of rocks is one of the main goals of texture analysis in geology. The frequent observation that the macroscopic structures are obliquely oriented with respect to the margins of ... -
