The Turgai plateau settles between the southern Ural Mountains and the Mugodzhars in the west, and the Kazakh melkosopochnik with raisings of the Kokchetav and Ulutau Mountains in the east. Unlike the territories to be mentioned next where folded Paleozoic structures surface, the Turgai plateau represents an epigerzinsk platform formation with rather deep burial of the Paleozoic base. Tectonically, it has a complicated correspondence with breaks of the Turgai syneklize, connecting along the Western-
The Turgai hollow is on a lowered narrow strip extending to the south in the middle of the described territory, almost in meridian direction. Absolute heights here are 100-
To the west and the east of the Turgai hollow the height increases to 200 meters, sometimes to 300 meters. The surface is combined by horizontal layers of paleogene and neogine adjournment. Paleogene (oligocene) is represented mainly by the solenoid clay and alluvial lake precipitation, and the neogene (miocene) mainly by continental sands.
The northern part of the Turgai plateau was poorly dismembered, where low hills and lake hollows are characteristic. To the south of the plateau, dismemberment was ordered by a system of hollows on the isolated table heights. Some that are lowered had transformed into flat remains, which tower over flat-
