Palynologie vybraných uhelných slojí a doprovodných sedimentů laziských a libiazských vrstev (moskov) v polské části hornoslezské pánve / Palynology of selected coal seams and accompanying sediments of the Laziska and Libiaz Beds (Moscovian) in the Polish part of the Upper Silesian Basin

This thesis summarizes palynological and paleontological study of the middle part of the Cracow Sandstone Series which is divided into the Łaziska (Bolsovian) and the Libiąz Beds (Asturian). Samples were obtained from the borehole G5 Dab nearby Jaworzno from both coal and non-coal sediments. Palynological study confirmed the stratigraphical gap between these two beds by observation of dissapearance of nine miospore taxons at the bottom of the Libiąz Beds (Torispora, Converrucosisporites, Schulzospora, Gillespieisporites, Schopfites, Convolutispora, Cristatisporites, Tripartites, Cingulizonates). Different ecological demands during the coal and non-coal sedimentation were confirmed. The sedimentation of the Łaziska coal seams is characterized by alternation of lycospore and densospore phases which confirmes alternation of the contrasting plant assamblages with a predominance of the arborescent lycopsids Lepidodendron and Lepidophloios and sub-arborescent lycopsid Omphalophloios. Arborescent lycopsids preferred planar (rheotrophic) mires. Plant assamblages with predominance of the lycopsid Omphalophloios colonized drier peat swamps with fluctuating water level (ombrothrophic). Peat swamp vegetation in Libiąz Beds was damper with localy transitional phase with increased incidence of the genus...
