05-BMG-CP3 Rock-Forming Processes

In "Principles of Petrology" the 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 cycles has regulated atmosphere and ocean compostions throughout our planet´s history. The course "Polarized-light Microcopy" includes an introduction to the theory of ploarized-light microscopy and a practical part in which thin sections and smear slides are examined under the microcope. Topics include: Introduction to polarized-light microcscopy in theory andpractise, Orthoscopy: refractive indexes, Relief, Beck-Line, birefringence (interference colors, extinction, optical character, and consocopy. Optical properties and identification of major rock-forming minerals will be covered.

1) Understanding the basic theory and practise of polarized-light microscopy
2) Determination of optical properties of rock-forming minerals in thin section and mineral identification
3) Application of petrological principles in analyzing rock- and mountain-forming processes and how they set ocean composition
4) Reading phase diagram and conducting simple computations of phase relations
