Syllabus

• Igneous rocks:
• Petrotectonic assemblages. Types of crust, continental and oceanic crust, origin of magmas, conditions of ascent and position of magmas, creation of rocks. Chemical restrictions, sources of primary magmas, ascent velocity in lithosphere. Experimental data -petrogenetic meaning of minerals, latice parameters and mineral colours as the source of information of the conditions of mineral creation in rocks, distribution of elements between coexisted minerals, gaseous-liquid inclusions, double-feldspar geothermometer, distribution of Mg, Fe and Ca, Al among the rock forming minerals. Trace elements of igneous rocks and their petrogenetic meaning. Contents of isotopes and the their interpretation.
• Basalts and ultramafic rocks. Types of basalts and their derivatives, basalt occurence: rift volcanism, volcanism of subduction zones, intra-plate volcanicm. Mineral composition, structures and chemical composition of basalts. Ultramafic igneous rocks. Rhyolites and andesites. Types and derivatives of rhyolites and andesites, occurence of rhyolites: hot spots, rifts, transform and tripple faults, volcanic arcs. Occurence of andesites and corresponding rocks. Mineral and chemical composition, structures of andesites. Ultramafic and mafic complexes and corresponding rocks. Shapes of ultramific and ultramafic-mafic rock bodies. Mineral and chemical composition, structures of ultramafic and mafic complexes. Stratified ultramafic complexes, ophiolite complexes, appinite type of ultramafic rocks.
• Granitoidal rock. Composition of granitoidal rocks. Structural and chemical variability. Petrogenesis of granitoidal rocks. Occurence of granitoidal rocks, their tectonic meaning and typology. Formation of granitoidal rocks (fractional crystallization, hybridization, granitization).
• Sedimentary rocks:
• Rock-forming minerals of sedimentary rocks - origin and petrogenesis: clay minerals, silicon oxides and hydroxides, feldspars, carbonates, phosphates, oxides, Fe, Mn, Al-hydroxides, sulfates, chlorides, iron sulfides. Organic matters. Rock-forming organism.
• Origin and evolution of sedimentary structures: Textural characteristic (distribution of grain size, the shapes of sedimentary particles, surface texture of sedimentary particles, matrix, cements and cementation, ooids and pisoids, spherulitic texture, primary and secondary porosity, permeability). Textural classification. Structural classification of sedimentary rocks. Outer and inner structures.
• Origin of sedimentary rocks: weathering processes (mechanical and chemical degradation of rocks, sedimentary cycle, soil formation, erosion. Transport (medium motion, grain flows, water transport, eolian transport, glacial and gravitational processes, orientation of grains). Sedimentation, types of deposition environments. Influence of the tectonic and climatic conditions, sedimentation velocity. Maturity of sediments. Diagenesis of sediments, diagenetic evolution (syndiagenesis, anadiagenesis, epidiagenesis), main phases arising during lithogenesis, geophysical and geochemical conditions of diagenesis, Diagenetic metasomatism. Anchimetamorphism.
• Recent sediments.
• Metamorphic rocks
• Individual types of metamorphic rocks will be treated with emphasis on the geotectonic setting of their genesis. Methods of metamorphic rocks studies aiming at determination of P-T conditions of their formation will be presented. This will include analyses of relationships between metamorphism and deformation, formation and use of mineral zoning, geothermobarometry, geochronology, petrogenetic grids and metamorphic P-T paths. Examples from the Bohemian Massif will be presented.
• 1. Metapelites, quartzofeldspathic rocks (orthogneisses)
• 2. Metabasic and mafic rocks.
• 3. Metacarbonates, calc-silicate rocks .
• 4. High temperature and ultra-high temperature metamorphism, low, medium and high pressure granulites, anatexis, contact metamorphism.
