BSc in Geosciences, Chemistry, or Physics. Basics in analytical chemistry, basics of stable isotopes geochemistry, good knowledge of fundamental math and physics. Entry exam to check prerequisite level takes place in May GFZ. Please also pre-register at dettlaff@gfz-potsdam.de

We explore the so-called „non-traditional“ stable isotopes, of which the minor shifts by isotope fractionation have been made detectable by multicollector ICP-mass spectrometry. These are for example the elements lithium, magnesium, silicon, calcium or iron. • Why do isotopes shift their relative abundances? Principles of mass-dependent isotope fractionation. Isotope fractionation during precipitation, mineral dissolution, weathering, uptake by higher plants, biomedical applications, the hydrosphere, and formation of the planets. Basics of MC-ICP-mass spectrometry: sample preparation, ionisation, ion optics and mass separation, detection systems, data evaluation.

Lectures will deal with applications (isotope fractionation in nature: rocks, weathering, rivers, plants, human nutrition)

Practicals will be daily and will use sophisticated clean labs and mass spectrometry equipment (multicollector ICP Ms) at GFZ Potsdam. Participants will do a small scientific project.

The course will take place at Earth surface Geochemistry at GFZ Potsdam. Each day 2h Lecture, 2h Lab practical, 2h Lecture, 2h Lab Practical
