Western structural closing of the Pripyat–Dneprov–Donetsk aulacogen

In segmented paleorift systems such as the Pripyat–Dnieper–Donetsk aulacogen, which penetrate deep into the continent from the side of the paleoocean margin and most often close here, each segment represents an autonomous structure of the lithosphere. The presented article shows that the tectonic position of the Pripyat paleorift as the western closing segment of the indicated aulacogen was due to a change in the intensity of syn-rift and plate-tectonic processes in the extended rift system from east to west. In the band of the Paleoproterozoic Fenno-Sarmatian collision, the Central Belarusian suture zone of the Central Russian transpression belt isolated by S. V. Bogdanova in 2018 was a blocking transverse barrier to relative development of Hercynian synrift processes in the western direction.
