The engineering-geological features of the sands included in the pre-Quaternary continental terrigenous formations (red and gray-colored, coal-bearing and lignite-bearing, molasses and molasses coal-bearing), which are widespread in Russia, are characterized. The results of studying the composition, structure, condition and properties of these soils within the various regions of Russia are presented.

In engineering geology sands are investigated from different positions, including from the point of view of their spatial distribution. The latter is especially important for the vast territory of our country. Schematic maps of the distribution of pre-Quaternary and Quaternary sandy soils on the Russian territory are compiled. The regularities of their distribution by area and section within platform and mountain regions are described.

Highlighting the sandy soil of Oltenia Plain calls for a better knowledge of their variability their correlation with major natural factors from each physical geography. Pedogenetic processes specific sandy soils are strongly influenced by nature parent material. This leads, on the one hand, climate aridity of the soil due to strong heating and accumulation of small water reserves, consequences emphasizing the moisture deficit in the development of the vegetation and favoring weak deflation, and on the other hand, an increase in mineralization organic matter. Relief under wind characteristic sandy land, soil formation and distribution has some particularly of flat land with the land formed on the loess. The dune ridges are less evolved soils, profile underdeveloped and poorly supplied with nutrients compared to those on the slopes of the dunes and the interdune, whose physical and chemical properties are more favorable to plant growth.Both Romanati Plain and the Blahnita (Mehedinti) Plain and Bailesti Plain, sand wind shaped covering a finer material, loamy sand and even loess (containing up to 26% clay), also rippled with negative effects in terms of overall drainage. Depending on the pedogenetic physical and geographical factors that have contributed to soil cover, in the researched were identified following classes of soils: protisols, cernisols, cambisols, luvisols, hidrisols and antrosols.Obtaining appropriate agricultural production requires some land improvement works (especially fitting for irrigation) and agropedoameliorative works. Particular attention should be paid to preventing and combating wind erosion.
