Timeliness of the work is that nowadays an important aspect of negative changes indication in ecosystem soil cover is geo-ecological monitoring organization and conduction which is effective tool of natural management efficiency within the territory under consideration due to Kazakhstan natural-resources development, mineral extraction and processing. Geo-ecological investigations according to the soil condition on the chalk deposits Shetpe South in the plant area "Caspian Cement" in Mangystau region were conducted with the purpose to define geo-ecological Kazakhstan soils state in chalk mining and processing areas in 2014-2017. 15 soil samples were taken in every year. Samples were taken from 0-20 cm depth. Soil analysis on heavy metals was carried out by atomic absorption method using the spectrometer MGA-915, and their content was compared with the existing MAC standards. Cartographic documents were made using GIS software products: Mapinfo Professional v.10.2, the SAS. Planet 160707. Scientific novelty is understood that according to the investigation results I was proved that soils differs with a very carbon high content, both from the surface and on the profile, their number varies from 1.39 to 9.19 %. The majority of soil samples on chromium, Nickel, lead and cadmium at trial sites P-1 (plant industrial site) and P-2 (chalk and dumps transportation area) were characterized by exceeding the MPC level for all years. The cadmium content in soils P-2 increased from 1.88 MPC to 2.1 MPC for 2014-2017. Heavy metals content in descending order is as follows: Cr > Ni > Pb > Cd > Cu > Zn > Mg according to the investigation results for the 2014-2017. 2 substances of the danger 2nd class are at the beginning of the row.
