Tectono-sedimentary evolution of the Pilsen Basin and characteristics of its mineral deposits
Michlová, Nikol ; Opluštil, Stanislav (advisor) ; Pešek, Jiří (referee)
The objective of this bachelor thesis is to provide an overview of tectono-sedimentary evolution of the Pilsen Basin based on published data and archived reports. Part related to mineral deposits evaluates economical potential of the basin in term of raw material, especially with respect to hard coal deposits. The qualitative parameters of coal are also provided in the second part of this bachelor thesis as well.
Lithofacies and cyclic pattern of the upper part of the Poruba Member (Serpukhovian) in the eastern part of the Ostrava-Karviná coalfield
Michlová, Nikol ; Opluštil, Stanislav (advisor) ; Jirásek, Jakub (referee)
The diploma thesis studies lithofacies and cyclic pattern of about 200 m thick upper part of the Poruba Member (Serpukhovian) in the Karviná area of the Ostrava-Karviná coalfield. The objective of this thesis is to identify laterally persistent cycles from the local ones by the set of cross-sections and to better understand their formation, especially the role of glacio- eustatic sea level changes. Set of cross-sections constructed from boreholes were used for this study. The three genetic cycles were identified in the thesis based on previous studies of Gastaldo et al. (2009). From base to top the cycles are the (i) Max, (ii) Otakar a (iii) Gaebler. Their thickness fluctuates between 19.9 and 109.9 meters. The genetic cycles are bounded, with one exception, by a transgressive erosional surface of important faunal marine bands. From the set of cross-sections and maps of thickness and sand content (%), constructed for individual genetic cycles, it is obvious that the area of maximum thickness corresponds to area of increased content of medium- and coarse-grained sandstone. Maxima of sand content and thicknesses follow NNE-SSW direction, which is in agreement with basin axis. These maxima are interpreted as areas occupied by fluvial channels that are responsible for deposition of coarse- grained...
