Die Eisrandtäler im Karakorum: Verbreitung, Genese und Morphodynamik des lateroglazialen Sedimentformenschatzes
(2014-08-11)The research study provides a contribution to the geomorphological survey of the lateroglacial landform assemblage along subtropical high mountain glaciers in the Karakoram (72°-79°E; 35°-36°N). The ice-marginal valleys ... -
Ejecta erosion, hydrological, and chemical lake evolution in the Ries impact basin (Miocene, Germany)
(2022-04-08)To inspect past environmental changes and potential habitability, the growing interests for the ancient Martian crater lakes call for better understandings of palaeolimnological evolution of impact crater lakes. Particularly, ... -
Electrical conductivity and hydrogen diffusion in synthetic orthopyroxene single-crystals
(2011-03-22)Charge transport mechanisms and the proton contribution to electrical conductivity of syn-thetic orthopyroxene single crystals could be inferred by combining results from hydrogen diffusivity ... -
Electromagnetic radiation as a tool to determine actual crustal stresses - applications and limitations
(2010-05-25)In the last decades natural Electro Magnetic Radiation (EMR) has gained more and more attention in the fields of material sciences and geosciences. Since EMR precedes material failure, it ... -
Elektroresistiver Effekt im sauerstoffdefizitären Manganit Nd2/3Sr1/3MnO3-/δ
(2006-08-01)In this work we investigated oxygen deficient Nd2/3Sr1/3MnO3-δ-ceramics with 0 < δ < 0.20. The T-δ phase diagram exhibits sequence of the paramagnetic, antiferromagnetic and two spin-canted (metallic and insulating) phases. ... -
Entgasung und Kristallisation beim Aufstieg dazitischer Magmen zur Erdoberfläche
(2014-10-29)In this study, kinetic processes during experimentally simulated ascent of dacitic magmas, based on eruption products of Taapaca volcano, were investigated. The focus was on degassing of water saturated samples and the ... -
Entwicklung eines statistischen Habitateignungsmodells zur räumlichen Vorhersage der Vorkommenswahrscheinlichkeit des Wachtelkönigs (<i>Crex crex L.</i>) im Nationalpark Unteres Odertal
(2006-03-29)Until the middle of the last decade, there had been little knowledge about the habitat requirements and conservation biology of corncrakes (Flade 1991). Many questions on these topics were ... -
Erdfallablagerungen des südlichen Harzvorlandes
(2005-03-23)Sediments from karst sínkholes of the Upper Permian (Zechstein) belt of southern Harz mountains are geochemically examinated. The aim of this research is the reconstruction of the ... -
Erhaltung der Bodenfruchtbarkeit unter Anwendung angepasster Anbausysteme in Bergregionen Vietnams
(2004-03-12)In sloping lands in Vietnam, the influence of topography, geology, morphology, climate, etc., and of human activities has resulted in serious environmental degradation, particularly of soil ... -
Evaluating the potential of I-type cosmic spherules as a proxy for the Δ’17O of atmospheric O2 for reconstructing paleo-CO2 levels and GPP throughout the Phanerozoic
(2024-12-09)Entirely molten micrometeorites, termed I-type cosmic spherules, are micrometer to millimeter-sized remnants of extraterrestrial Fe, Ni-rich metal that can be recovered on Earth. I-type cosmic spherules acquire all oxygen ... -
Evaluation of 87Sr/86Sr, δ18O, δ2H, and Cation Contents as Geochemical Tracers for Provenance and Flow Paths of Saline Solutions in German Zechstein Deposits
(2009-05-15)The assessment of flow paths of saline solutions that percolate through evaporitic deposits is an important task for a mining company to avoid loss of a mine by flooding. In this study, the ... -
Evolution and decay of peneplains in the northern Lhasa terrane, Tibetan Plateau
(2014-10-21)The key issue of this thesis is the evolution and decay of peneplains, which are distinctive geomorphological structures in the southern area of the Tibetan Plateau. Additionally, evidence concerning the uplift history and ... -
Experimentelle Bestimmung der Depositionsgeschwindigkeit luftgetragener Partikel mit Hilfe der Eddy-Kovarianzmethode über einem Fichtenaltbestand im Solling
(2002-10-08)The aim of this dissertation was to determine the deposition velocity of atmospheric particles for a spruce stand as a function of the particle size and the atmospheric conditions using the ... -
Experimentelle Untersuchung zur Auflösungskinetik von Kaolinit und Montmorillonit in Anwesenheit von Sulfat, Phosphat, Amino- und Carbonsäuren sowie Harnstoff im offenen und geschlossenen System
(2006-03-08)The aim of the present study is to decipher mechanisms and kinetics for the reactions at the solid/liquid interface by experiments at well defined physical/chemical conditions. For this ... -
Experimentelle Untersuchungen zu Mechanismen von druck- und temperaturinduzierten Phasenübergängen
(2021-10-18)Under the influence of pressure and/or temperature changes, crystalline materials undergo a phase transition. The directions of the crystalline unit cell before and after the phase transition can show orientation relations. ... -
