The study of the ecological state of soils on the Caspian Sea coast in the area of the Tengiz field is of great practical importance. It is necessary for the control over an ecological condition of soils and an estimation of a degree of its pollution on the present position. Morphological description of soils by horizons, granulometric composition, physical and chemical properties of soil by horizons and content of oil products have been studied. The obtained outcomes will act as an initial stage in analyzing polluted soil due to an oil spill. Additionally, it will offer a dependable evaluation of the extent and rate of pollution. The observation process involved employing commonly accepted techniques and methods. The soils of the study area are represented by sandy, sandy loam and light loam varieties. The thickness of the humus horizon was not high, the cation exchange capacity of the soils was <5 mg-eq/100 g, the content of physical clay in the surveyed soils did not exceed 10 %. The oil content is below the permissible level. The study concludes that no impact of the Tengiz deposit on the environmental condition of soils in the coastal zone of the Caspian Sea has been identified.
