Abstract. The paper addresses the mathematical modeling of the dynamics of a locally nonequilibrium (in time) geomigration process in a geoporous environment saturated with a salt solution, on the basis of a sub-diffusion model described by a system of equations of distributed order. Fig.: 1. Refs: 18 titles.

Keywords: mathematical modeling, nonclassical models, nonequilibrium geofiltration, model of distributed order, system of differential equations, boundary-value problems, approximate solutions.
