Learning Objectives
Interpretation of the petrogenetic processes of the igneous, sedimentary and metamorphic rocks, even with respect to their geodynamic environment.
Program
The minerals of the magmatic rocks and the modal mineralogy composition. Modal classification and chemical compositions of the rocks. Chemical classification of the igneous rocks and the fundamental petrochemical concepts (saturation indexes). Normative composition of the igneous rocks. Magma generation: examples from the mantle and crust systems. Rising and fractional crystallization of the magmas. Magma assimilation. Magma mixing. The structures of the igneous rocks. Examples of magmatic systems with two and three components. Crystallization of magmas in the presence of eutectic and peritectic points. Magmatic series and geodynamic environment. Sedimentary processes and the sedimentary rocks. Terrigeneous siliciclastic rocks and their classification. Carbonate rocks and their classification. General framework of the metamorphic processes. The factors of the metamorphism: temperature, pressure, presence of fluid phases, deformation. The metamorphic reactions. The metamorphic transformations: two- and three-phase associations and relative ternary diagrams. Nomenclature of the metamorphic rocks. The metamorphic facies: mineral assemblages and reaction isogrades. Metamorphic facies and thermal gradients: series of metamorphic facies and P-T petrogenetic grids.
Description and classification of rocks under the plane polarized light microscope. Fundamentals of optical mineralogy. Detection of the main rock-forming minerals of the igneous, sedimentary and metamorphic environment. Optical properties of feldspars and methods for determining the anorthite contents in the plagioclases. Microstructures and thin section classification of the most common igneous rocks. The QAPF classification diagram, the diagrams for the classification of the ultramafic rocks. The TAS chemical diagram for the classification of volcanic rocks.
Learning Achievements (Dublin Descriptors)
Understanding the petrogenetic significance of the magmatic, sedimentary and metamorphic rocks. Aquiring the capacity of describing the rocks with an attitude to classifying them even with the polarized light optycal microscope, in particular those of magmatic environment.

- Assessment
Practical/written examination based on description and classification of a rock in thin section. Oral examination.
- Disability and Specific Learning Disorders (SLD)
Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.
To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
