Isotope Geochemistry and Geochronology

A.Y. 2018/2019
Overall hours
Learning objectives
The course aims to allow the student to use stable and radiogenic isotopes to track natural and anthropogenic process in the different earth reservoirs. The course also aims to allow the student to understand and apply the most used techniques for the geochronology of rock and minerals. The activity in the laboratory aims to apply to natural cases the arguments described during the course.
Expected learning outcomes
The student will acquire the basic knowledge to understand the principal isotope systematics used in the geosciences and how they are applied to track planet evolution and the evolution of the environment. The student will also acquire the basic knowledge of radiometric dating and the tools to choose between the different dating techniques as a function of the study case. Particular attention will be given to interpretation and evaluation of radiometric ages.
