651-4049-00LConceptual and Quantitative Methods in Geochemistry
Der erfolgreiche Abschluss des Bachelor-Kurses Geochemie (651-3400-00L) ist für diesen Kurs Voraussetzung.
3 KP2GO. Bachmann, D. Vance, G. De Souza, A. Hunt, J. Leuthold
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.

651-4931-00LSeminar I: Heat and Mass Transfers in Magmatology1 KP1SJ. Leuthold
KurzbeschreibungHeat and mass transfers from the mantle to the crust control many aspects of the differentiation of our planet, including (1) primitive melt chemistry, (2) layering of the crust, (3) type of volcanic eruption. This year, we will focus on processes in crystal mushes (formation, crystallization, remobilization).
LernzielThis class will allow the students to learn about the modern methods and ideas on heat and mass transfers in magmatology through classic and recently published papers. Communication of scientific results to the scientific community and the public is critical. In the class, the students will read and analyse scientific papers and discuss them orally to the class. The students will also create a Wikipedia page and reformulate scientific results for the public.
InhaltThe class will focus mostly on 1) reading literature on topics of interests, 2) oral and written presentations of the papers, 3) exercises illusrating the topic, to allow students to work by themselves on some well-defined problems.
