Skupiny faunistických horizontů Enny a Barbory v hornoslezské pánvi.

Abstract

The dissertation deals with the study of the Enna and Barbora group of faunistic horizons in the Upper Silesian Basin. The Enna group of faunistic horizons, together with the Barbora group of faunistic horizons, are among the important correlation horizons in the Ostrava Formation. The Enna group of faunistic horizons is part of the Hrušov Member and in the Czech part of the basin, the Barbora group of faunistic horizons is part of the Jaklovec Member and in the Polish part of the basin it belongs to the Poruba Member. The introductory part presents a summary of information regarding the Upper Silesian Basin and its geological structure. The following chapter deals mainly with the fauna of the Enna and Barbora groups of faunistic horizons, which are an integral part of these marine horizons. The next chapter deals with the definition of their lower and upper boundaries, and derives from them the monitored parameters such as thickness, sandiness, development of faunistic horizons and coal-bearing capacity. The monitored parameters are described in the spatial development of the Enna and Barbora groups of faunistic horizons in the Upper Silesian Basin, and in addition they also contain assembled new models. This dissertation also includes prepared maps that indicate the occurrence of marine, freshwater and lingual fauna. It also contains twelve lithological-correlation sections across the entire Upper Silesian basin, which point not only to the deposition of sediments in the Enna and Barbora groups of faunistic horizons, but also the distance between these sea horizons, where it is evident that these two significantly studied horizons approach each other in the east of the basin. The results of the work also addresses the unification of the Enna and Barbora groups of faunistic horizons in the east in the Polish part of the basin and includes a model that shows this distance between the horizons. The dissertation presents not only the already known information regarding the Enna and Barbora group of faunistic horizons, but also new knowledge relating to their development within the entire Upper Silesian Basin and, most importantly, new maps and models that provide an idea of the occurrence and development in the Upper Silesian Basin. Because these data cannot be found in any published map form, I’ve tried to process these map materials.
