The textbook presents a complete course of the fundamentals of physical geochemistry. The subject and methods of physical geochemistry as a science about the physical and chemical laws of the formation of minerals, rocks and ores are considered. The general principles of the thermodynamics of equilibrium natural systems, which are a special type of system with completely mobile components, are given. The main thermodynamic relationships characterizing natural processes are derived, their application is shown.

The issues of theory, topology, and methods for constructing diagrams used in geochemistry, petrology, and the study of mineral deposits are presented in detail.

For students, graduate students and all specialists involved in the study of the physical and chemical laws of natural processes.
