In this paper the investigation results of thermal springs of the Mutnovsky Volcano (Kamchatka, Russia) are provided. Mud pots in the Donnoe Field of this volcano have a unique solution composition. High concentrations of a wide spectrum of chemical elements such as Al, Ti, V, Cr, Ni, Co, REE and PGE were discovered there. To explain the mechanisms of solution formation it was made an attempt to describe the fluid evolution and the resulting mixing waters by physical and mathematical modeling. A model illustrates fluid migration from magma chamber to the surface. It is shown that formation of brines corresponding to mud pots composition is possible under the secondary boiling border.
