Sedimentologic and microfacies study of the Suchomasty Limestone at Zlatý kůň Hill near Koněprusy (Lower Devonian - Dalejan)
 Polecha, Roman ; Vacek, František (advisor) ; Čáp, Pavel (referee)
This master thesis comprises results of sedimentologic, microfacies and physical stratigraphic research of the Suchomasty Limestone at Zlatý kůň Hill near Koněprusy (Prague Basin, Lower Devonian - Dalejan). Six instructive sections have been selected for detailed study. Physical stratigraphic records (MS and GRS) have been used for correlation of two lithologically different sections (Section I - to the East of the Herget Quarry and Section IV - near the entrance to the Koněprusy Caves). This comparison showed that both sections correspond to the same stratigraphic level, and thus can be included in one sedimentary system. This assumption is also supported by preliminary results of studies on stratigraphic distribution of conodonts. Stratigraphic variations in MS and GRS may also be used for reconstructions of sedimentary environment and its evolution (e.g., changes in sea level). However, all measured parameters show only low oscillations and reflect probably only local conditions. Five microfacies types corresponding to three facies belts have been identified in the studied sections. The lower part of the Suchomasty Lm. is dominated by fine-grained limestones (MF 1 - tentaculite wackestone/packstone) in the NW part of the area (Section IV - near the entrance to the Koněprusy Caves). They deposited in a...
