Structural-denudation relief (low elevations). Its surface is the most ancient, belongs to the Azkamar denudation-accumulative cycle and is highly elevated in the study area, covered with eluvial, alluvial-deluvial and deluvial- ­proluvial deposits of undivided Quaternary age. This relief is characterized by a tectonic structure and lithological features of the constituent rocks that are difficult to denudate. These include the Alyaudintau, Dultalitau, Karakyr, Saksandara and Maimanaktau uplands
At the tops of the hills there are small outcrops of Upper Cretaceous shell limestones (Cr 2 ).
Limestones and gypsums of the Bukhara stage ( Pg ) occupy small areas and also have outcrops within the peaks. The described area also includes deposits of the Tandyrcha ( N 2 th ) and Guzar suites ( N 2 gz ).
Deposits N 2th _ are widely distributed in the apical and peripheral ­parts of the above uplands and are represented by homogeneous fine-grained brownish-gray sandstones, sandstones are weakly cemented, with calcareous-argillaceous cement, with inclusions of calcareous concretions in their top.
Stripped thickness of sandstones N 2 th is 316m (well 43k/b). Deposits N 2 gz distributed in the plain part of the region under Quaternary ­deposits and are represented by clays, siltstones, and sandstones. Their stripped thickness is 150-200 meters (wells 80, 93). The total thickness of the Guzar suite of the Upper Pliocene reaches 700-800 m and more meters.
In the area of the Kysylysh well on the slope of the eroded sai (in outcrops) there are outcrops of the Azkamar complex ( plQi ^), represented by interbedded strata ( 1 - 2 m) of conglomerate, gravelstone, sandstone. Their total apparent thickness is 10.0m
Conglomerates and gravelites ( Qi ak ) were also discovered by exploration pit No. 153 in the southeastern part of the region, on the northern slopes of the Karakyr and Saksandar mountains. The general slope of the surface is to the north and northwest. The dissection is due to the presence of valley-forming depressions Kyzylishvansai, Kunya-Sardobasai, Alyaudinsai and others, elongated in the northern and northwestern directions. Their relative deepening averages 10-20m. The surface of the ridged upland is composed of eluvial -deluvial formations, and the bottom of the depressions is composed of deluvial -proluvial deposits of an undivided Quaternary complex with a thickness of 1-3m, in some places up to 5m (see excavation pit No. 55, 56, 107 and 144).
Lithologically, these deposits are represented by sandy loams, sands with inclusions of calcareous concretions and limestone fragments.
