Target group: MSc students who would like to do an MSc thesis project in ore geology or hydrothermal geochemistry, want to work in the exploration or mining industry, or who take the specialization in bedrock geology. First year of MSc studies. Aim After completion of the course the student has general knowledge of hydrothermal geochemistry, metal transport and deposition in hydrothermal systems. Content Properties of water and salty fluids at elevated temperatures and pressures, experimental techniques in hydrothermal geochemistry, principles of mineral and gas solubility in aqueous solutions, solubility of rock-forming minerals, speciation and transport of ore metals, systematics of ore metal complexing in hydrothermal systems, essentials of fluid-rock equilibria, chemistry of hydrothermal alteration, chemistry of ore precipitation mechanisms, stable isotope geochemistry of hydrothermal systems, simple calculations with SUPCRT92. Evaluation Grading is based on the term paper assignment. Teacher Thomas Wagner Previous studies: BSc in Earth Sciences and Ore Geology (54106) are required. Additional info: Students who want to do an MSc thesis project in ore deposit geology or hydrothermal geochemistry should have completed this course. Course is entirely in English, including lectures and writing of the final term paper. Course practices: Mainly lectures. Each student writes a term paper (about 10 pages) on a specific topic in hydrothermal geochemistry Textbook: Basic textbook: Barnes, H.L. (1997) Geochemistry of hydrothermal ore deposits.
