W3 KP2GO. Bachmann, M. Schönbächler, D. Vance
KurzbeschreibungThis course will introduce some of the main quantitative methods available for the quantitative treatment of geochemical data, as well as the main modelling tools. Emphasis will both be on conceptual understanding of these methods as well as on their practical application, using key software packages to analyse real geochemical datasets.
LernzielDevelopment of a basic knowledge and understanding of the main tools available for the quantitative analysis of geochemical data.
InhaltThe following approaches will be discussed in detail: major and trace element modelling of magmas, with application to igneous systems; methods and statistics for calculation of isochrons and model ages; reservoir dynamics and one-dimensional modelling of ocean chemistry; modelling speciation in aqueous (hydrothermal, fresh water sea water) fluids.

We will discuss how these methods are applied in a range of Earth Science fields, from cosmochemistry, through mantle and crustal geochemistry, volcanology and igneous petrology, to chemical oceanography.

A special emphasis will be put on dealing with geochemical problems through modeling. Where relevant, software packages will be introduced and applied to real geochemical data.
SkriptSlides of lectures will be available.
Voraussetzungen / BesonderesPre-requisite: Geochemistry (651-3400-00L), Isotope Geochemistry and Geochronology (651-3501-00L).

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.
