Tremadoc of the East European Platform: lithofacies and palaeogeography

In the Tremadoc the palaeobasin of the East European Platform was a NW-SE elongated inland sea between the Baltic and Ukrainian shields. It opened into the Iapetus Ocean in NNW. The present Moscow Syneclise may have had a connection with the Palaeo-Ural Sea, too. Terrigenous sedimentation represented by sandy-silty and pelitic material predominated. On the basis of the sediments preserved, we can distinguish three main regions with different sedimentary conditions in the Tremadoc basin: Scandinavia-Poland, Northern East Baltic, Moscow Syneclise.
