Isotopengeochemie des Heidelberger Neckarschwemmfächers - Th/U-Ungleichgewichte und Pb-Isotopie quartärer klastischer Sedimente
An einem 280 m tiefen Bohrkern aus dem Bereich des Heidelberger Neckarschwemmfächers wurden die langlebigen Radionuklide 238U, 234U, 230Th und 232Th und Blei-Isotopenverhältnisse mithilfe der Thermionen-Massenspektrometrie (TIMS) untersucht. Anomal positive d234U-Werte können mit einer …

Sedimentary facies reconstruction and kinematic restoration of an Upper Permian tight gas field, north-western Germany
This study of a tight gas reservoir, located at ~4200 metres depth in the Upper Rotliegend II (Upper Permian) of north-western Germany, includes a geological framework model for the sedimentary facies distribution, which is strongly influenced by the structural grain. Research focused on …
