Airborne Thermal Data Identifies Groundwater Discharge at the North-Western Coast of the Dead Sea
(Remote Sensing, 2013)A qualitative and quantitative monitoring of groundwater discharge was conducted based on an airborne thermal campaign undertaken along the north-western coast of the Dead Sea in January 2011 to contribute to the relatively ... -
Archaea in past and present geobiochemical processes and elemental cycles.
(Archaea (Vancouver, B.C.), 2013)For a long time, Archaea have been considered as an ancient prokaryotic group comprising specialists restricted to narrow ecological niches. This opinion might have been supported by the characteristics of the first ... -
Higher subsoil carbon storage in species-rich than species-poor temperate forests
(Environmental Research Letters, 2014)Forest soils contribute ca. 70% to the global soil organic carbon (SOC) pool and thus are an important element of the global carbon cycle. Forests also harbour a large part of the global terrestrial biodiversity. It is ... -
Pinning down the solid-state polymorphism of the ionic liquid [bmim][PF6]
(Chemical Science, 2012)The solid-state polymorphism of the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate, [bmim][PF6], has been investigated via low-temperature and high-pressure crystallisation experiments. The samples have ... -
Comparative in vitro study and biomechanical testing of two different magnesium alloys.
(Journal of biomaterials applications, 2014)In this in vitro study, magnesium plates of ZEK100 and MgCa0.8 alloy similar to common titanium alloy osteosynthesis plates were investigated as degradable biomedical materials with a focus on primary stability. Immersion ... -
Mineralogical and geochemical characterization of high-medieval lead–silver smelting slags from Wiesloch near Heidelberg (Germany)—an approach to process reconstruction
(Archaeological and Anthropological Sciences, 2010)Here, we present detailed electron microprobe analyses and age data of high-medieval lead–silver smelting slags. The mineral composition data provide a database of all silicate and oxide phases in the slag. Bulk chemistry ... -
Time constraints on the tectonic evolution of the Eastern Sierras Pampeanas (Central Argentina)
(International Journal of Earth Sciences, 2009)The application of the SHRIMP U/Pb dating technique to zircon and monazite of different rock types of the Sierras de Córdoba provides an important insight into the metamorphic history of the basement domains. Additional ... -
Geometry and formation of gypsum veins in mudstones at Watchet, Somerset, SW England
(Geological Magazine, 2008)Gypsum veins and faults were studied in red mudstones of the Upper Triassic Mercia Mudstone Group, in the Bristol Channel Basin, exposed in E–W-trending cliffs at Watchet on the Somerset Coast (SW England). In nodular ... -
Characterizing uranium solubilization under natural near oxic conditions
(Uranium in the Environment, 2006)A 782 d solubilization study using not shaken batch experiments and involving one uranium-bearing rock and three natural carbonate minerals was conducted to characterize uranium (U) leaching under oxic conditions. Results ... -
Impact of MnO2 on the efficiency of metallic iron for the removal of dissolved CrVI, CuII, MoVI, SbV, UVI and ZnII
(Chemical Engineering Journal, 2011)The idea that manganese oxide (MnO2) sustains the reactivity of metallic iron (Fe0) is investigated in this study. A multi-elemental aqueous system containing CrVI, CuII, MoVI, SbV, UVI, and ZnII (each about 100 μM) was ... -

Mapping leaf area index over semi-desert and steppe biomes in kazakhstan using satellite imagery and ground measurements
(EARSeL eProceedings, 2009)Maps of peak seasonal leaf area index (LAI) were produced using the Normalised Difference Vegetation Index (NDVI) from SPOT VEGETATION (VEG) satellite at 1 km resolution over a large region in the semi-arid zone of Kazakhstan. ... -

High-Resolution Imaging of Texture and Microstructure by the Moving Detector Method
(Textures and microstructures, 2003)In order to describe texture and microstructure of a polycrystalline material completely, crystal orientation g={?1F?2} must be known in all points x={x1?x2?x3} of the material. This can be achieved by locationresolved ... -

Age constraints on faulting and fault reactivation: a multi-chronological approach
(International Journal of Earth Sciences, 2009)Movement within the Earth’s upper crust is commonly accommodated by faults or shear zones, ranging in scale from micro-displacements to regional tectonic lineaments. Since faults are active on different time scales and can ... -
Nd–Sr–Hf–O isotope provinciality in the northernmost Arabian–Nubian Shield: implications for crustal evolution
(Contributions to Mineralogy and Petrology, 2009)Multi-isotope study including whole-rock Nd–Sr, single zircon Hf, and SIMS δ18O analyses of zircons sheds light on magma sources in the northernmost Arabian–Nubian Shield (ANS) during ~820–570 Ma. Reconnaissance initial ... -
The Sierra Ballena Shear Zone in the southernmost Dom Feliciano Belt (Uruguay): evolution, kinematics, and deformation conditions
(International Journal of Earth Sciences, 2009)The Sierra Ballena Shear Zone (SBSZ) is part of a high-strain transcurrent system that divides the Neoproterozoic Dom Feliciano Belt of South America into two different domains. The basement on both sides of the SBSZ shows ... -
