Ore-forming processes

Master course offered annually in the summer semester

This course is devoted to processes of metal distribution, transport and enrichment in Earth's lithosphere. We use process-oriented approach from mantle-derived mafic magmas and their metal budget through silicic magmas, their volatiles, exsolution and fractionation of metals towards a large group of hydrothermal processes and fluid-rock interaction. The course concludes with fluids generated during crustal metamorphism and in sedimentary basins, and ore-forming processes in near-surface environments (weathering and supergene mobility).

Instructors: Prof. David Dolejš, Dr. Harri Geiger
