Modern solid, fractured macroporous loam and sandy loam lie buried on the roof Khvalynsk sea plains and leaving on the day surface. Loam and sandy loam in their natural state are characterized as subsiding. A characteristic feature of the geological structure solidnogo basin of Caspian basin is the presence of powerful strata of salts, dividing the entire section on two structural floor above-salt and sub-salt. Deformation properties salts are characterized by indicators: the modulus of deformation, elastic modulus, shear G, Poisson's ratio. Rock salt is represented by halite, sodium chloride up to 96 %, and insoluble residue to 10.14 %. The density of salt is 2140-2280 kg/m , the uniaxial compressive strength varies from 19,3 to 36,7 MPa, the Poisson ratio from 0,2147 to 0,307, the modulus from 9,5 to 36,1 HPa.
