Ore-bearing strata of Zheskazgan ore district has a cyclic structure. Each cycle begins layers of coarse-grains rocks, sandstones and finely ends dispersed clastic rocks. Detailed petrographic studies of ore-bearing rock strata showed a mixed composition. The main parameters of the sedimentation conditions include physical conditions: the density and viscosity of sediment-environment, pool depth, speed, direction and stability of the flow. By chemically sediment conditions are redox reaction, salinity and temperature of the medium. Tectonic activity area and climate are also important factors of depositional area.
