Brief description of the lecture:
The composition of igneous rocks and their classification. Silicate melts and volatiles in magmatic systems. Crystallization of rock-formating magmatogenes. The crystallisation of the magma, nucleation and crystal growth. The texture and the structure of the igneous rocks. Magma intrusion into the crust and igneous rock bodies. Eruptive and effusive rock bodies. The development of magma. Magmatic differentiation. Petrotectonic associations (divergent plate boundaries and the related basaltic rocks, mantle plume, island arc rocks, plateau basalt, island arc magmatism, ophiolites, rocks related to the lime-alkali convergent plate boundaries, granitoid rocks related to the continental collision, anorogenic A-type rocks, continental rift associations: bimodal and alkaline rocks, alkali dyke rocks of cratones: lamprophyres, lamproites).
The classification of metamorphic rocks. The types of metamorphic reactions. The metamorphosis of quartz-feldspar rocks and pelites. Metabasites, the concept of metamorphic facies. The metamorphosis of marbles and lime silicates, the role of fluids in metamorphic processes. Thermobarometry calculations. Thermobarometric modelling, the P – T path. The structure and the texture of metamorphic rocks; pre-, syn- and postkinetic textures. The geodynamical importance of metamorphic rocks.
