The area territory has passed a long and difficult way of geological development and consequently differs tectonic complexity and an age variety of structural elements.

The area is located within several structural formations of a palaeozoic: a folded complex of the Central Kazakhstan (Kazakh small hill), Zaysansky folded system (Rudnyi, Southern Altay, the Kalbinsky ridge), Chingiz-Tarbagataysky meganticlinorium (ridges of Tarbagatay, Chingiz) and the West Siberian platform structure (Kulundinsky plain). Structural complexes are combined by sedimentary, metamorphic, magmatic formations of the bottom and top palaeozoic with prevalence of vulkano-sedimentary breeds (sandstones, aleurolites, limestones, gravelites, lavas, The area territory has passed a long and difficult way of geological development and consequently differs tectonic complexity and an age variety of structural elements.

On kaledonsko-gertsinskoe the folded basis in a number of places younger structural complexes which have resulted tectonic lowerings and accumulation of deposits sea (Western Siberia) and continental lake-alluvial genesis (the Zaysansky, Chiliktinsky, Alakolsky, Kenderlyksky, Leninogorsk hollow) are imposed.

The territory of the East Kazakhstan region belongs to area of secondary mountain building, accumulative plains, denudation raised plains. The basic orographical units are mountain constructions of Rudnyi and Southern Altay, Saur-Tarbagatay, Kalby, Kazakh small hill, Priirtyshsky plain, Zaysan and Alakol intermountain hollows.

Rudniy Altai is presented by system of the ridges located on a right bank of Irtysh between mouths of Uba and Narym Rivers. East and central its parts are represented by ridges: Listvyaga (2577), Holzun (2599), Coke (2598 m), Tigiretsky (2007), Ivanovo (2776), Ubinsky (1962) and Ulbinsky (1894). Among separate heights and ridges intramountain hollows - Zaysansky, Borodino, Leninogorsk are isolated.

 

Southern Altay separates from Rudnyi Altay an intramountain Narymo-Buhtarminsky hollow. It consists of system of ridges with absolute heights from 500-600 m in the west to 2800-3600 m in the east and the southeast. Below an alignment surface the abrupt and sharply dismembered hollows are located: Markakolsky, Verhnekarakabinsky, Bobrovsky and others.
Ridges of Saur and Manrak located to the south of the Zaysansky hollow, represent accurately outlined mountain raisings to 3500-3900 m (Muztau, 3816), are limited by intermountain Zaysansky and Chiliktinsky hollows.
The ridge of Manrak has the maximum height of 2053 m (Shorbas) in east part where it is jointed with Saurom. The ridge of Tarbagatay (Tastau, 2991) is to the east located.
The Kalbinsky uplands are located on a left bank of the river Irtysh and stretched from its big bend around a mouth of the river Narym to a valley of the river of Charms in the west. Absolute heights change from 400 to 1606 m in the central part.
Kazakh small hill - the transitive type from mountain area to plain, represents alternation of raised ridges, hills, hills with extensive plains and low mountains files. Within East Kazakhstan are allocated isolated low mountains files: ridges of Kanchingiz (1076), Chingiztau (1077), Akshatau (1305) in the center, mountains Sagymzhol (1215) in the east, Kotanemel (1089), Karaungir (865) in the southwest, mountains Myrzhik (970) in the northeast. In the east Kazakh small hill incorporates to ranges of Altay, Tarbagatay, Saura.
Priirtyshsky plain - homogeneous, flat, gently rolling, wake drainage a surface in which central part the valley of Irtysh is located.
The Zaysansky hollow represents the extensive intermountain deflection executed by lake-alluvial mezozoy-Cainozoic adjournment by capacity to 2000 m. the Lowered part with absolute heights to 400 m the water area of the Buhtarminsky water basin (the lake occupies Zaysan). In areas of ancient accumulations of deltoid character and destruction of granite intrusions sandy files of Kiin-Kerish, Kyzyl-godfather, the Aygyr-godfather were formed.
The Alakolsky intermountain hollow dividing hills of Tarbagatay and Dzungarian Ala Tau, represents the extensive plain formed by deposits of ancient Alakol, surrounded with powerful cones of carrying out of the rivers running into group of Lakes: Alakols, Sasykkol, Koshkar-kol and Zhalanash  which are settling down in a hollow. Round lakes wide lake accumulative terraces with approach to mountains rising on height to 90 meters are observed.
In Metal genes the relation the area settles down within three ore belts: the Altay, including 5 zones, Zharma-Saursky - 3 zones and Chingiz-Tarbagatay - 2 zones.
In total in area territory it is reconnoitered and it is maintained about 130 mineral deposits: ore raw materials (polymetallic, rare metals ores), fuel and energy raw materials (coal, oil, brown coal, combustible slates), building materials, precious and ornamental stones.
