651-3501-00LIsotopengeochemie und Isotopengeologie3 KP2GS. Bernasconi, D. Vance
KurzbeschreibungDie Vorlesung behandelt die wichtigsten in Geochemie und Geologie verwendeten Systeme radioaktiver und stabiler Isotope. Anhand von Fallbeispielen wird gezeigt, wie die Isotopengeochemie zur Lösung grundlegender Fragen der Erdwissenschaften beiträgt.
LernzielVermittlung von Grundwissen und Anwendungen der wichtigsten Systeme radiogener und stabiler Isotope.
InhaltFolgende Methoden werden eingehender besprochen: die radioaktiven-radiogenen Systeme Rb-Sr, Sm-Nd, U-Th-Pb und K-Ar, sowie die stabilen Isotopensysteme des Sauerstoffs, Kohlenstoffs, Wasserstoffs, Stickstoffs und Schwefels.

Es wird gezeigt, wie diese Methoden in den folgenden Gebieten angewandt werden: Geochemie der Gesamterde, Datierung, Paläotemperaturen, Krustenentwicklung, Mantelreservoirs, Ursprung von magmatischen Gesteinen, thermische Geschichte der Kruste, Sedimentdiagenese, die Bedeutung von Fluiden in der Kruste, hydrothermale Mineralisation, Paläoozeanographie, biogeochemische Kreisläufe.

651-4057-00LClimate History and Palaeoclimatology3 KP2GS. Bernasconi, B. Ausin Gonzalez, A. Fernandez Bremer, A. Gilli
KurzbeschreibungThe course "Climate history and paleoclimatology gives an overview on climate through geological time and it provides insight into methods and tools used in paleoclimate research.
LernzielThe student will have an understanding of evolution of climate and its major forcing factors -orbital, atmosphere chemistry, tectonics- through geological time. He or she will understand interaction between life and climate and he or she will be familiar with the use of most common geochemical climate "proxies", he or she will be able to evaluate quality of marine and terrestrial sedimentary paleoclimate archives. The student will be able to estimate rates of changes in climate history and to recognize feedbacks between the biosphere and climate.
InhaltClimate system and earth history - climate forcing factors and feedback mechanisms of the geosphere, biosphere, and hydrosphere.

651-4225-00LTopics in Geochemistry3 KP2GS. Bernasconi, G. Bernasconi-Green, D. L. Cook
KurzbeschreibungThis course aims to present and discuss advanced topics in geochemistry based on the critical reading of research papers. Themes will vary from year to year and suggestions from students are welcome. The format of the course will be: one or more lectures introducing a theme, followed by a presentation of one or more papers by a student or group of students.
LernzielThe goal of the course is discuss topics in advanced geochemistry which were not covered in other general and specialized geochemistry courses. In addition, we aim at training the student's ability to critically evaluate research papers and to summarize the findings concisely in an oral presentation.
InhaltThemes will vary from year to year and suggestions from students are welcome.
Some possible topics are:
Organic geochemistry.
Isotope geochemistry of organic matter: carbon, hydrogen and nitrogen.
Multiply-substituted isotopologues.
Mass-independent fractionations.
Mass transfer and isotopes in modern and ancient ocean-floor hydrothermal systems and subduction zone environments.
Noble gas geochemistry: terrestrial and extraterrestrial applications
LiteraturWill be identified based on the chosen topic.
