Abstract (in english)
   The positive delta 18O anomaly was documented on carbonates N of Koneprusy (Barrandian area). It ranges within Pragian-Eifelian time-span. This unusually strong anomaly is coupled with a moderate depression of delta 13C values, as well as increased contents of selected non-ferrous metals and rare elements (ICP-MS trace element data for brachiopod samples). An eustatically half-separated ocean/marine basin has been interpreted, where deep parts of water column were typical with anoxia, toxic pollutants and temporarily anomalous isotopic compositions.
