THE QUASIPLATFORM SEDIMENTS OF THE EAST EUROPEAN PLATFORM

Abstract

The subject of this paper is the structure of the peculiar rock complex of the East European Platform, composed of the rocks dated 1750 Ma to 1300 Ma and known as a quasiplatform rock cover. The western and eastern segments of the platform differ greatly in terms of the lithology and thickness of their rocks. The quasiplatform sediments have been subdivided into the lower and upper subtypes. The lower subtype is developed mainly in the west, and the formation of the structural features composed of these rocks is supposed to have been associated with the process that operated in the Ural Mountains.
