Investigation of the effect of contamination with chemical elements on changes in the content of clay fraction in sandy-clay rocks

Abstract

The reasons for soil pollution that causes deviations in the mineral composition are considered. It is noted that changes in the chemical composition of the soil lead to a change in various fractions. This process is considered on the example of clay fractions. The sandy-clay rocks of the Leningrad region in the Russian Federation are considered. Modeling of situations on taking samples of rocks for research has been performed. Comparison of the calculations with the results of express control of the state of rocks by other methods is carried out. The method for determining the content of clay fraction in sandy-clay rocks has been determined.
