Introduction to Geochemistry

Lecturers: Florian Adolphi, Marcus Elvert, Simone Kasemann, Florence Schubotz

Content:

We will convey basic knowledge regarding the origin of the solar system and elements as well as the chemical composition of the Earth. These basics are essential for all geochemisty related subjects in subsequent semesters.
Key geochemical concepts such as fluxes, reservoirs, and residence times will be introduced and illustrated with examples. Isotopes are introduced and their utility as geochemical tracers as well as sources of information about geobiological processes will demonstrated with examples. The hydrological cycle will be introduced. Emphasis will be placed on the physical and chemical properties of water, physicochemical reactions in solution, and on water-rock reactions. In organic chemistry, we will introduce chemical compound classes, natural products, and introductory knowledge in stereochemistry. The knowledge will be required for an understanding of the composition of organic matter in sedimentary rocks. Chemical degradation reactions that occur in nature on a range of temporal scales will be treated. Additionally, relevant basic knowledge in analytical techniques such as chromatographic separation and mass spectrometry will be discussed.

Competences:

The students will gain basic knwoledge of chemical principles that are relevant to the geosciences and required for subsequent emphasis of geochemistry as well as a mechanistic understanding of numerous general investigative techniques within the geosciences.

Assessment:

Written exam
