The results of studying the stratotypes of Ulutau-the Arganatinskaya structural-formation zone located in the western part of Central Kazakhstan, are highlighted. Intensely metamorphosed volcanogenic-sedimentary strata and intrusive formations take part in its structure. The existing features of stratigraphic sections of Precambrian sediments allow us to distinguish different structures. Located in the central part of the Maytyubinsk structure is composed of rocks of the Borovian series of the Lower Proterozoic. The Karsakpai structure located to the east is made of rocks of the Karsakpai (Akdym) series of the Upper Proterozoic
