Results obtained from the laboratory research of the isotope composition of water occluded in fine-dispersed ground revealed that the water-soil interaction processes are accompanied by 16О, 18О, Н, 2Н-isotope fractionation depending on soil structure and properties, with the isotopic composition of bound water being lighter, as compared to free water.
