Objectif

This module illustrates the wide range of applicability of stable (light and heavy) and radiogenic isotopes to an advanced understanding of magmatic, metamorphic, surface, tectonic and ore-forming processes. The course will consist of both lectures (50%) and practical exercises (50%).

Contenu

1. Magmatic systems.
a. Stable isotopes for source fingerprinting and reconstructions of magmatic processes
b. Radiogenic isotopes for source fingerprinting and magmatic processes reconstruction
c. Dating magmatic rocks and magma chamber processes
2. Metamorphic systems.
a. Metamorphic reactions and stable isotope compositions
b. Dating of metamorphic events
3. Thermochronology.
a. Low temperature thermochronology (FT, U-Th-He)
b. The Ar/Ar thermochronometer
c. High temperatute thermochronology (U-Pb)
4. Sedimentary systems
a. Clastic systems: provenance through radiogenic and stable isotopes and zircon dating
b. Carbonate systems: C- and Sr-isotope chronostratigraphy, reconstruction of paleo-chemical and physical parameters and processes (e.g., B, Ca, Zn isotopes), U-series dating
5. Surface systems
a. Tracing sources of pollutants in the environment and reconstructing surface processes with stable and radiogenic isotopes
6. Ore systems
a. Signatures of stable light and heavy isotopes in ore systems
b. Tracing fluid and metal sources with radiogenic isotopes
c. Dating ore deposits
