Devonian and Lower Carboniferous limestones in the southernmost part of the Moravian Karst
Two limestone outcrops in the southernmost part of Maravian Karst area in the surroundings of Bedřichovice have been studied from the viewpoint of biostratigraphy, sedimentology, structural geology and microfacies analysis. The foraminiferal and conodont fauna from Bedřichovice abandoned quarry suggests a Late Frasnian age while in the Líšeň – Zetor quarry, the limestones are of a Late Tournaisian – Middle Viséan age.
The sedimentological and microfacies investigations indicate that limy material was carried by low density turbidity currents from the carbonate platform. The sedimentation of distal calciturbidites correspond 10 the facies D (Bedřichovice) and facies C (Líšeň – Zetor quarry) of the outer carbonate apron (MULLINS and COOK 1986). The sequence of rocks in Bedřichovice is strongly tectonicaly affected by folds and dislocational deformations.
