Variscan subduction-related plutonism in the French Massif Central
Usmanova, Diana ; Janoušek, Vojtěch (advisor) ; Špillar, Václav (referee)
The French Massif Central belongs to the Moldanubian Zone, which is an internal part of the Variscan Orogen. The Massif was formed during six tectonic-metamorphic events and has a nappe structure. The Muscovite-bearing Peraluminous Granitoids (MPG), Cordierite-bearing Peraluminous Granitoids (CPG), K-rich Calc-alkaline Granitoids (KCG), and Amphibole-bearing Calc-alkaline Granitoids (ACG) types of granitoids were intruded into the nappe units during the Carboniferous. The formation of FMC granitoid plutons was predominantly linked to continental collision; only the ACG plutonites are older, typical of magmatic arcs. These amphibole-bearing calc-alkaline quartz diorites to tonalites are common in the western French Massif Central (Limousin region), where a 250 km long belt known as the "Limousin tonalite belt" is found. Its linear shape and characteristic geochemical composition suggest a subduction-related origin. Newly obtained geochemical data from the Limousin region indicate an intermediate composition (52-57 wt% SiO2), a metaluminous, subalkaline character, and place the samples in the calc-alkaline series. Furthermore, enrichment of Large Ion Lithophile Elements (LILE), depletion of High Field Strength Elements (HFSE), negative europium anomaly (Eu/Eu* = 0,63-0,92) and relatively low initial...
Evolution of accretionary orogenic systems - the nature and geodynamics of the western Mongolian Altai
Soejono, Igor ; Janoušek, Vojtěch (advisor) ; Xiao, Wenjiao (referee) ; Finger, Friedrich (referee)
Long-lived accretionary evolution of the Mongolian part of the Central Asian Orogenic Belt was intensively studied during the last decades, however, it is not completely known yet. Types of geodynamic processes forming this orogenic system and their timing are addressed through petrological, geochemical and/or sedimentological study combined with U-Pb zircon geochronology. The publications included in this thesis present research of two magmatic and one sedimentary system in the western Mongolia. Both the ancient magmatic complexes and sedimentary successions provide opportunity to study geotectonic evolution in a different way. Therefore, mutually combined results of these two geological disciplines allow more complex insight into the geodynamics of the region. The geochemical, isotopic and geochronological investigations of the high-grade basement complexes in the eastern Hovd Zone reveal an existence of the Early-Mid-Ordovician intra- oceanic arc and associated fore-arc volcano-sedimentary complex. The superimposed Mid- Silurian intra-plate magmatism is interpreted as a result of lithospheric thinning related to the same but already retreating subduction. Striking similarities of the studied basement with neighbouring Lake Zone margin suggest that the both units originally belonged to a single...
The Origin of Compositional and Textural Zoning of Shallow-Level Granitoid Plutons
Trubač, Jakub ; Janoušek, Vojtěch (advisor) ; Broska, Igor (referee) ; Siebel, Wolfgang (referee)
The principal goal of this Ph.D. Thesis is to contribute to the research on formation of compo- sitional and textural zoning in shallow-level plutons. Processes responsible for emplacement of individual plutons/pulses and the origin of compositional zoning in are addressed in a great detail, from the pluton-scale down to the micro-scale. The main emphasis in the more focused part of this text is on a combination of various quanti- tative data sets from two well-selected plutons (the Říčany Pluton in the Central Bohemian Plu- tonic Complex and the Melechov Pluton in the Moldanubian Batholith). These detailed studies are supported by further research on the Štěnovice, Čistá and Ševětín plutons. In this way we cover the evolution of Variscan magmatism in the heart of Bohemian Massif in its entirety, from Late Devonian till Permian. The thesis is based on combining field and structural studies (including the anisotropy of mag- netic susceptibility, AMS), textural analysis, petrological, geochronological and geochemical methods with geophysical investigations. Mathematical approaches have been designed and applied to the interpretation of geochemical data, with potential applications to other igneous systems. I strongly believe that only such comprehensive studies on well-selected case examples have a...
Macroeconomic development of the Czech Republic after admission to the European Union
Janoušek, Vojtěch ; Nečadová, Marta (advisor) ; Pošta, Vít (referee)
The thesis deals with the analysis of macroeconomic development of the Czech Republic after admission to the European Union. Attention is also paid to development of gross domestic product and its structure. The thesis also mentions the interpretive limitations of GDP and some alternative indicators. The last part focuses on the process of real convergence and comparison with the countries of EU.
Aplication Old Testament Ethics chosen on specific corruption cause
JANOUŠEK, Vojtěch
The thesis examines the Old Testament ethical sources associated with the problem of corruption. The theoretical part tries to characterize corruption. Then it explains how social sciences attempt to view this problem, especially law, sociology and ethics. The analytical part tries to apply the Old Testament ethics on one particular case of corruption and to evaluate it from the view of social sciences.
