The conceptual and mathematic models of the transport of a mantle substance with reduced relative to the enclosing medium density to the Earth crust are introduced. Based on them, the platform for parametric modeling of the substance accumulation in a depth chamber, formation and evolution of the mantle-crust migrant has been created as software Vladi Overpressure. The software provides to simulate forming of the depth accumulative chamber of three different shapes as well as forming and evolution of the mantle-crust migrant of three different shapes. The rate of the migrant ascent can be calculated by five equations (Newton’s, von Rittinger’s, Stokes’s, Allen-Lyaschenko’s, Spera’s) that relate the following parameters: density, strength, temperature, dynamic viscosity, yield strength of the enclosing medium, and migrant density.
