ABSTRACT
The relatively quick displacement of fairly large volumes of free gravitational water in an aquifer or in fractured zones calls for successful application of the proposition of the continuity of the medium known in hydromechanics of liquids. In this case the movement of groundwaters as a multicomponent solution is considered as a non-kinetic flow of a water mass moving in the pore and fracture space of the hydrolitho-spheric system. Another mathematical model of movement of water in the HLS uses the molecular-kinetic theory of solutions. Studies have demonstrated that practical problems of prognosis of groundwaters and also determination of hydrodynamic parameters for various kinds of particles can be successfully solved on the basis of such a model. The formation of economic minerals deposits is related to the activity of groundwaters primarily under conditions of development of clayey rocks which traditionally serve as aquicludes. The theory of delayed flows offers an explanation for the processes of formation of such deposits.
