Nine sedimentary sequences are recognized in the Ordovician of the Siberian Platform. These sequences correspond to sea level fluctuations of the 3rd order, from 1 to 6 My. Correlation with the sequences recognized in the Ordovician of the Russian Platform suggest their possible eustatic nature. Cold water nontropical carbonates are suggested in the Ordovician of the Tungus Syneclise, which may be explained by the upwelling of cold oceanic waters. The upwelling was caused by re-distribution of oceanic currents due to largescale tectonic events in the mid-Ordovician. The Ordovician evolution of the Siberian Platform was much more similar to that of the North American Platform than of the Russian Platform.
