The central part of the East European Plain is characterized by a relatively calm relief with an elevation of up to 400 m and gentle declines. The Northern Hills, the Valdai, Smolenskaya, Central Russian and Volga uplands, and the Oka-Don Plain are confined to the Moscow Depression of the Eastern European Platform. The depth of the crystalline basement of the platform, which has a sharply dissected relief here, is, according to drilling data, 30-2900 m. Moreover, altitude fluctuations reach up to 1500-2000 m. at distances of 100-150 km. The maximum sedimentary rock strata overlap the ancient crystalline basement in the area of the Caspian lowland. Its depth is up to 10 km or more. As a result of active intra-terrestrial processes, oscillatory movements continuously occurred within the central part of the East European Platform. Some sections rose, others bent and sank. Such rises and falls are extremely slow. It takes many tens of millions of years for the formation of uplifts or subsidences of sections of the platform, which usually covered vast areas. These processes intensified in some places, and weakened in others. During the period of active deflections, the sunken areas were flooded by the seas, which were formed inside the continents either due to local internal runoff or due to the waters of the World Ocean. Such seas were shallow and had sloping, low-lying shores. Large-scale organogenic marine sediments have accumulated on their bottom for many tens of millions of years. Some deflections of the platforms were filled with continental strata of river, lake, Aeolian and other origin. The rising sections of the platforms, as a rule, were freed from shallow seas, experienced increased processes of destruction and demolition of loose sediments.


Both marine and continental precipitation accumulated on a highly layered crystalline basement. A two- to three-kilometer thick layer of marine and continental sediments lies almost horizontally above a complexly unsettled crystalline base — the remnants of Precambrian mountains. Here, sedimentary rocks (clastic, chemical, and organogenic) of Paleozoic age are replaced by Mesozoic strata (Triassic, Jurassic, and Cretaceous periods) and overlain by Paleogene, Neogene, and Quaternary sediments.
