East European Platform or Russian Platform is a large and flat area covered by sediments in Eastern Europe spanning from the Ural Mountains to the Tornquist Zone and from the Caspian Depression, Peri-Caspian Basin to the Barents Sea. Over geological time the platform area has experienced extensional tectonics, extension, tectonic inversion, inversion and compression. It has an area of about 6 million square kilometer, km2. The East European Platform sediments can be classified into the following groups: a "protoplatform" of metamorphic rock, metamorphosed sediments at the bottom, a "quasiplatform" of slightly deformed sediments, a "cataplatform", and a "orthoplatform" at the top. The Mesoproterozoic Jotnian, Jotnian sediments of the Geology of the Baltic Sea, Baltic area are examples of a "quasiplatform". The oldest preserved continuous sedimentary cover in the platform date to the Ediacaran#Ediacaran and Vendian, Vendian about 650 million years ago. The cycles of deposition of platform sediments are related to the development of nearby orogeny, orogenies like the Timanide orogeny, the Uralian orogeny, the Variscan orogeny, Hercynian orogeny and the Caledonian orogeny.
The platform hosts numerous ancient rifts or aulacogens some of which date to the Riphean Stage, Riphean of the Proterozoic.
In the Devonian, Late Devonian rifting and magmatic activity occurred within the platform leading to the formation of the Dnieper-Donets Rift. This event was possibly caused by a cluster of mantle plumes.
