Knowledge
The student who successfully completes the course will have the ability to demonstrate a solid knowledge of the main geochemical processes that are involved in the water-rock interation process. He will be aware of the principal methods of acquisition and elaboration of fluid geochemistry data (classification of waters, hydrogeochemical geothermometers etc.). The student will have a solid knowledge of stable isotope geochemistry (particularly oxygen, hydrogen, carbon, chlorine) and its use for environmental applications and for tracing the water-rock interaction processes. The student will be able to demonstrate advanced knowledge of methods of investigation of fluid inclusions and on the use of fluid inclusion data in the study of active and fossil hydrothermal systems.
Assessment criteria of knowledge
