Abstract

ORIG CZ

V originále

The mid-Fammenian Annulata events are supposed to be connected with an episodic sea level rise, which interrupt the global trends of climatic cooling during the Famennian (Sandberg et al. 2002). The fauna of the Annulata events from the Moravian Karst was discovered for the first time during the late 19th century and later described by Rzehak (1910) from the vicinity of Ochoz u Brna. The event beds were later recorded by Dvořák et al. (1988) from the western Mokrá quarry near Brno. The current investigation is focused on four sections near Ochoz, Hostěnice and Mokrá villages in the southern part of the Moravian Karst. These successions of the Křtiny Limestones of the Líšeň Formation are considerably condensed. According to the presence of Palmatolepis glabra lepta, Palmatolepis minuta minuta and Palmatolepis rugosa trachytera, the event bed near Ochoz might be correlated with the Lower Annulata event. All these taxa range to the Lower Annulata event but disappear below the Upper Annulata event in various German, Polish and Moroccan sections (Hartenfels 2011). The event beds in the two sections near the village of Hostěnice provided rather poor conodont fauna. Stratigraphically important conodonts such Palmatolepis glabra lepta and Palmatolepis rugosa trachytera were recorded below the event beds only. Thus, it cannot be clearly recognized, if these event beds near Hostěnice represent the Lower and/or the Upper Annulata events. The sample from the event bed in the western Mokrá quarry provided infrequent conodonts including Palmatolepis glabra lepta, which might indicate the Lower Annulata event. All studied sections were measured by the field gamma-ray spectrometer. Higher values of uranium corresponding to the event beds probably reflect anoxic or hypoxic conditions, and enable to correlate the Annulata event beds. This is in accord with the data from the Kowala quarry, Holly Cross Mountains, Poland (Bond & Zatoń 2003).
