Early Eocene magnetostratigraphy and tectonic evolution of the Xining Basin, NE Tibet
(Basin Research, 2022-10-12)The Cenozoic strata of the Xining Basin, NE Tibet, have provided crucial records for understanding the tectonic and palaeo‐environmental evolution of the region. Yet, the age of the lower part of the sedimentary stratigraphy ... -
Early Holocene aeolian sediments in southwestern Crete−preliminary results
(Mediterranean Geoscience Reviews, 2021-07-27)The soilscapes along the southern and western coast of Crete (Greece) are dominated by coarse-grained reddish-brown slope sediments whose natural (pre-anthropogenic) configuration and properties are difficult to reconstruct ... -
Ecological and biogeochemical change in an early Paleogene peat-forming environment: Linking biomarkers and palynology
(Palaeogeography, Palaeoclimatology, Palaeoecology, 2015)Sphagnum moss is the dominant plant type inmodern boreal and (sub)arctic ombrotrophic bogs and is of particular interest due to its sensitivity to climate and its important role in wetland biogeochemistry. Here we reconstruct ... -
Eduard Suess: the first honorary president of the Geologische Vereinigung, is 190 years old
(International Journal of Earth Sciences, 2021-09-27)This paper is a remembering the first honorary president of the Geologische Vereinigung on his 190th Anniversary. He still illuminates our path in our endeavours to understand not only our planet, but also others in our ... -
Eemian landscape response to climatic shifts and evidence for northerly Neanderthal occupation at a palaeolake margin in northern Germany
(Earth Surface Processes and Landforms, 2021-09-14)The prevailing view suggests that the Eemian interglacial on the European Plain was characterized by largely negligible geomorphic activity beyond the coastal areas. However, systematic geomorphological studies are sparse. ... -
Effect of iron and nanolites on Raman spectra of volcanic glasses: A reassessment of existing strategies to estimate the water content
(Chemical Geology, 2017)The effect of iron content and iron nanolites on Raman spectra of hydrous geologically-relevant glasses is presented. Current procedures to estimate the water content using Raman spectra were tested to explore potential ... -
Effect of pumice and sand on the sustainability of granular iron beds for the aqueous removal of CuII, NiII, and ZnII
(CLEAN - Soil, Air, Water, 2013)Current knowledge of the basic principles underlying the design of Fe0 beds is weak. The volumetric expansive nature of iron corrosion was identified as the major factor determining the sustainability of Fe0 beds. This ... -
Effects of CO2 and Ocean Mixing on Miocene and Pliocene Temperature Gradients
(Paleoceanography and Paleoclimatology, 2022-02-11)Cenozoic climate changes have been linked to tectonic activity and variations in atmospheric CO2 concentrations. Here, we present Miocene and Pliocene sensitivity experiments performed with the climate model COSMOS. The ... -
Effects of conversion of native cerrado vegetation to pasture on soil hydro-physical properties, evapotranspiration and streamflow on the Amazonian agricultural frontier.
(PloS one, 2017)Understanding the impacts of land-use change on landscape-hydrological dynamics is one of the main challenges in the Northern Brazilian Cerrado biome, where the Amazon agricultural frontier is located. Motivated by the gap ... -
Effects of Insect Mass Outbreaks on Throughfall Composition in Even Aged European Pine Stands - Implications for the C and N Cycling
(Journal of Earth Science & Climatic Change, 2011)In this paper we report on the herbivore-affected C and N concentrations in the throughfall and altered canopy to soil transfer during a Pine Lappet (Dendrolimus pini L) mass infestation in 60-year-old Scots Pine (Pinus ... -
Effects of lianas and Hurricane Wilma on tree damage in the Yucatan Peninsula, Mexico

Effects of mixing granular iron with sand on the efficiency of methylene blue discoloration
(Chemical Engineering Journal, 2012)The influence of granular sand on the efficiency of metallic iron (Fe0) for the discoloration of a methylene blue (MB) solution was investigated in the current work. The initial MB concentration was 10 mg L-1 and mass ... -
Effects of sample storage and shell orientation on LA-ICPMS trace element measurements on deep-sea mussels.
(Scientific reports, 2015)Geochemical markers are being increasingly applied to fundamental questions in population and community ecology in marine habitats because they allow inferences on individuals dispersal, but vital effects, small sample ... -
Effects of selected ligands on U (VI) immobilization by zerovalent iron

Effects of the presence of pyrite and carbonate minerals on the kinetics of the uranium release from a natural rock
(Journal of radioanalytical and nuclear chemistry, 2006)The influence of calcite, dolomite, pyrite and vaterite on the kinetics of uranium (U) release from a natural rock under relevant i.e. field conditions has been investigated. The time dependence of the U release has been ... -

Efficiency and Accuracy of Micro-Macro Models for Mineral Dissolution
(Water Resources Research, 2020)Micro-macro models for dissolution processes are derived from detailed pore-scale models applying upscaling techniques. They consist of flow and transport equations at the scale of the porous medium (macroscale). Both ... -
