Syllabus
  • 1) Introduction, tasks and methods of petrological work, petrology vs. Petrography, experimental petrology, applied petrography - petrography of technical substances, technical petrography and geology. Short overview of principal historic moments in the evolution of igneous petrology 2) The formation of magmatic rocks in the crust and mantle, physical properties of the magma, geotectonic position of igneous rocks - overview of models 3) Temperature and pressures of the formation of igneous rocks, measurement of magma temperature. Composition, origin, and conditions of magma creation. Viscosity, diffusion, formation of crystals in the melt, degasification of the magma and causes of ebullience. 4) Differentiation and crystallisation of magma - homogenous, heterogenous 5) hysico-chemical conditions of formation and ascent of igneous rocks, physico-chemical conditions of formation and ascent of igneous rocks 6) Rock-forming minerals of igneous rocks, their formation, division, and importance for genetic conclusions. 7) Temperatures and pressures of the formation of rock-forming minerals:  petrogenetic significance of minerals,  lattice parameters as a source of information on conditions of mineral formation in rocks,  colour of minerals as a source of information on of mineral formation in rocks,  temporal relations of mineral formation in rocks 8) Textures and structures of igneous rocks, their genetic importance 9) Chemical composition of igneous rocks, relation between chemical and mineral composition. Causes of differences in the composition of igneous rocks, significance of feldspars, quartz, and foids for classification of igneous rocks 10) Classification of igneous rocks 11) Experimental data, temperatures and pressures of the formation of rocks and their minerals - distribution of elements among coexisting minerals, fluid inclusions, two-feldspar geothermometer, distribution of Mg and Fe and Ca and Al among rock-forming minerals 12) Trace elements of igneous rocks and their petrogenetic significance. Contents of isotopes and their interpretation. Geochemical criteria for distinction of igneous rocks 13) The rate of igneous rock formation. 14) Criteria of tectogenesis and tectonic position of igneous and effusive rocks 15) The formation of ultrabasic, basic, intermediary and acidic magma, magma ascent, differentiation, crystallisation of artificial melts 16) Systematic and reginal petrography
