Based on the airborne geophysical data, the anomalies of the natural radioactive element (NRE) ratio values above a background level are determined for different types of metasomatites in Priamurye. Three characteristics of the anomalies of the NRE ratios and the temperature and pH indicator values are related by a differential equation. A solution of the equation is found in partial derivatives. This dependence describes mathematically the regional metasomatism processes and is graphically displayed in ellipses or degenerated hyperbolas. The established regularities are confirmed by the experimental data. It is shown that a set of the characteristic NRE ratios, and the temperature and pH indicator unambiguously, within the limits of permissible errors, define any type of metasomatites in Priamurye. The derived dependence can be used during the airborne geophysical survey for mapping the regional metasomatic systems, and ore nodes and ore fields. The application of such a technique at the initial stages of mineral prognosis allows us to dramatically increase the reliability of the results and localize perspective areas.
