Abstract
We have compared quantitative characteristics of the macro- and microcomponent composition of pore solutions in bottom sediments obtained by their direct analysis and those calculated on the basis of the composition of water extracts taking into account water content of the samples. In the result of the study it was shown that the method of water extracts may be used to determine salinity and chemical composition of natural pore waters in low-permeable argillaceous deposits with different lithification rates. It was also shown that an analysis of water extracts does not allow determining the exact composition of the natural pore solution, but may be used for the evaluation (within the measurement error) of chlorine, sodium, and bromine content.
