Principles of Petrology

fundamental concepts of the rock cycle, including mantle melting, magmatism, weathering, diagenesis and compaction, subduction and metamophism will be covered in lectures and exercises on the basis of petrological principles. The use of phase diagrams will be tought and practised. Simple calculations will also be conducted to demonstrate the thermodynamic underpinning of phase diagrams. Rock-forming processes in a range of geotectomic settings will also be discussed. Emphasis will be put on how the rock cycle has regulated atmosphere and ocean compostions throughout our planet´s history.

Application of petrological principles in analyzing rock- and mountain-forming processes and how they set ocean composition
Reading phase diagram and conducting simple computations of phase relations
Understanding the role of rock-forming processes and weathering in our planet`s geochemical cycles
