N2 - Climate changes close to the Lochkovian-Pragian Event are still widely discussed. Carbonate delta 18O and delta 13C and conodont apatite delta 18O from medial to distal carbonate ramp sediments were analysed to provide further stable isotope data from the stratotype area in the Prague Basin. The uppermost Silurian to lower Emsian delta 18O trends are put into an updated conodont biostratigraphy framework. Carbonate delta 18O and delta 13C are discussed in the context of facies-dependent diagenesis. The delta 13C pattern measured from different sections enables the correlation of intervals with development of different facies inside the Prague Basin. Positive delta 13C shifts are often coupled with trends of decreasing computed gamma-ray (CGR) values interpreted as regressions, whereas negative delta 13C shifts commonly coincide with opposite trends in CGR. The Lochkovian-Pragian boundary interval coincided with an increase in carbonate delta 13C and an increase in the delta 18O of conodont apatite and carbonate, which we interpret as consequence of climate cooling. Generally, the Lochkovian was warmer than the Pragian and earliest Emsian.
