Central Belorussian massif

The Central Belorussian massif is the most elevated part of the Belarusian anteclise in the east of the Grodno and west of the Minsk regions, where the crystalline basement in some places faces the anthropogenic surface.

It is limited in the north-east by the Nalibotsky fault, in the south by the Svislatsky and Lyakhovitsky faults and by a series of northern instrumental faults of the Pripyat trough , in the west by an iso-gypsum foundation surface of 200 m. It has the shape of a wedge extended from west to east along the Grodno - Kopyl line , 230 km long , the width of the base is 160 km.

The surface of the crystalline basement in the central and eastern parts is elevated on the Bobovnyansky ledge, on the northern and western slopes it is lowered to -200 m. It is a system of block uplifts composed of the Mostovsko-Dyatlovsky block with smaller protrusions and the Bobovnyansky ledge .

The platform cover is composed of fragments of the Volyn and Valdai Vendian series, which occur mainly on the northern and southern slopes and in the lowlands between the blocks in the central part, as well as Cretaceous , Paleogene , Neogene and anthropogenic deposits. In the east, in the lower part of the cover, fragments of the Polessye series of the middle-upper Riphean are preserved. Cretaceous and anthropogenic sediments occur in a continuous cover. In the central and western part (Mostovsko-Dyatlovsky block), the foundation is overlain by Cretaceous deposits, which are most common in the eastern part (Bobovnyansky ledge), and in places, in the central part - by anthropogenic.

By the time of formation, the Central Belorussian massif as part of the Belarusian Anteclise is the structure of the most ancient Vendian foundation. As an independent performance in the Baltic Shield, it existed in Volyn times. At the Caledonian stage, in connection with the deflection of the Baltic Syneclise , the Podlaska-Brest Depression and the Mazowiecko-Lublin Depression, the Central Belorussian massif finally became distinct and formed the core of the Belarusian Anteclise .
