The lecture will provide an overview of the application of radioactive and stable isotopes to high-temperature geological systems, including igneous and metamorphic samples, as well as magmatic and hydrothermal ore deposits.
In the first half of the Module, you will learn in greater detail about radioactive decay systems (i.e. Pt-Re-Os, Sm-Nd isotopes) to a different rock types produced as a result of high-temperature processes (metamorphism, melting and crystallization). All these systems can be used to identify specific processes, which range in scale from crystallization of silicate and sulfide minerals from magmas, to core formation in planetary bodies.
The second half of the Module will deal with non-traditional stable isotope systems and how they can be used to complement data from radioactive decay systems in a variety of applications. These systems will include an overview of B, Si, Mo, Ti, V, Cr, and Fe isotopes to characterize processes and variables ranging from fluid-rock interaction, crustal recycling, redox conditions, mantle source compositions and many others.
The lecture will be complemented by a practical (Übung) where geochemical data from natural and experimental samples will be discussed and evaluated. Moreover, case studies involving different high-temperature geological settings will be discussed.
