Brief description of the lecture:

The crystallisation of the igneous rock-forming minerals, phase diagrams, crystal formation from melts, one-component systems, two-component systems, crystal-melt equilibrium of the basaltic magma, feldspar-melt equilibrium system, the olivine-pyroxene equilibrium system, the equilibrium system of aqueous magmas, the geothermy and geobarometry of magmatic systems. The differentiation of the magma (discrimination diagrams, closed-system magma differentiation, open-system magma differentiation, hybrid magmas, the differentiation of basaltic magmas, calc-alkaline differentiation). The chemistry-based classification of magmatic rocks, compatible, incompatible elements, trace element geochemistry, isotope geochemistry. Petrotectonic associations (divergent plate boundaries and the related basaltic rocks, mantle plume and island arc rocks, plateau basalt, island arc magmatism, ophiolites, rocks related to the calc-alkaline 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 types of metamorphic reactions. The metamorphosis of quartz-feldspar rocks and pelites. The metamorphosis of metabasists. The metamorphosis of marbles and lime silicates, the role of fluids in metamorphic processes. Metamorphic crystallisation, the texture analysis of metamorphic rocks. Thermobarometry calculations, the most important thermometers, barometers. Thermobarometric modelling, the TWQ and the Domino/Theriak softwares.

Plastic deformation: lineation, the development of foliation, schistosity, gneiss structures. The microstructure of igneous and metamorphic rocks, their static and dynamic recrystallisation. The principles of isotope geochronology, isotope systems. K/Ar, Ar/Ar, Rb/Sr, U/Pb, Th/Pb, Pb/Pb systems, the geochemical age. The P-T-t-d development path of metamorphic rocks and its geodynamic interpretation.

 

Practical Course:

The textural, rock chemical, geochronological, mineral chemical and thermo-barometric aimed complex analysis of the igneous and the metamorphic rock samples based on granitoid, basalt, gneiss, mica and metabasic rock series.
