- Abstract
The paper presents results of modeling the chemical interactions of Quaternary meteoric waters with siltstones of the upper part of the Vendian Padun Formation of the Mezen Syneclise, Arkhangelsk region, Russia. Equilibrium and equilibrium-kinetic approaches were applied. It is shown that under conditions of intensive water exchange and low temperature, due to low rates of interaction of minerals with water, the redox buffer of rock-forming minerals at this stage of the process makes a subordinate contribution to the dissolution of uranium. Therefore, for a sufficiently long time, the main agent of mobilization of uranium in rocks is oxygen dissolved in water.
