Differentiating between hydrothermal and diagenetic carbonate using rare earth element and yttrium (REE+Y) geochemistry: a case study from the Paleoproterozoic George Fisher massive sulfide Zn deposit, Mount Isa, Australia
(Mineralium Deposita, 2021-05-12)Carbonate minerals are ubiquitous in most sediment-hosted mineral deposits. These deposits can contain a variety of carbonate types with complex paragenetic relationships. When normalized to chondritic values (CN), rare-earth ... -
Differentiation of asteroids in the early solar system from Hf-W systematics
(Univ. Köln, 2008)The first major differentiation in primitive planetesimals is the formation of metal- or metal-sulfide cores. To constrain the time of asteroidal differentiation, meteoritic metals and silicates coexisting with metals were ... -
Digital enhancement of landsat data, spectral analysis and GIS data integration for geological studies of the Derudeb Area, Southern Red Sea Hills, NE Sudan
(Selbstverlag Fachbereich Geowissenschaften, Freie Universität Berlin, 1997)Die Geologie des Arbeitsgebietes Derudeb ist mit Methoden der Fernerkundung und Geo- Informationssystemen auf der Grundlage einer begrenzten Datenbasis untersucht worden. Als Ergebnis wurde ein geologisches Kartenblatt ... -
Digitale Datenerfassung zur Flächenverwaltung von Mooren mit Georadar und Photogrammetrie
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 37; 2007)Abstract: The methods of Ground Penetrating Radar and Photogrammetry are both excellent instruments for digital data collection. Ground Penetrating Radar in use on site with GPS-measurement delivers high definition digital ... -
Digitization of imaging plates from Guinier powder X‐ray diffraction cameras
(Journal of Applied Crystallography, 2022-08-24)A Guinier camera equipped with an imaging plate is used to investigate and eliminate the sources of instrumental errors affecting the quality of the obtained scanned Guinier data. A program with a graphical user interface ... -
Dimensioning metallic iron beds for efficient contaminant removal
(Chemical Engineering Journal, 2010)Remediation of contaminated groundwater is an expensive and lengthy process. Permeable reactive barrier of metallic iron (Fe0 PRB) is one of the leading technologies for groundwater remediation. One of the primary challenges ... -
Dinoflagellaten-Zysten als Paläoumweltindikatoren im Spätquartär des Europäischen Nordmeeres
(Univ. Bremen, 2007)Dinoflagellate cysts, paleoceanography, paleoenvironment, Late Quaternary, Norwegian-Greenland Sea. - Dinoflagellate cysts have been investigated in nine short sediment cores as well as two long sediment cores from the ... -
Dinosaur tracks 2011 - an International Symposium, Obernkirchen, April 14-17, 2011; Abstract Volume and Field Guide to Excursions
(Univ.-Verl. Göttingen, Göttingen, 2012)The Early Cretaceous (late Berriasian) Bückeberg Formation in the southern Lower Saxony Basin, to the west and to the south of Hannover, yields abundant and diverse dinosaur tracks, known since the late 1870s. After a few ... -
Dinosaurian survivorship schedules revisited: new insights from an age‐structured population model
(Palaeontology, 2021-10-13)Little is known of dinosaur population biology due to insufficient information on age‐dependent fecundities and mortalities. So far, survivorship curves (SC) of only six dinosaurs (four tyrannosaurs, one ceratopsian, one ... -
Dipolarization Fronts in the Jovian Magnetotail: Statistical Survey of Ion Intensity Variations Using Juno Observations
(Journal of Geophysical Research: Space Physics, 2023-04-12)Energetic particle acceleration and energization in planetary magnetotails are often associated with dipolarization fronts characterized by a rapid increase of the meridional component of the magnetic field. Despite many ... -
