This work investigates the fundamental principles governing the formation and spatial distribution of metasomatic rocks within the Earth's crust. D.S. Korzhinskii, a prominent Soviet geologist, utilizes thermodynamic principles and chemical equilibrium models to explain how mineral assemblages change during metasomatic processes. The text provides a rigorous framework for understanding how infiltrating solutions alter the composition of host rocks through chemical exchange.

Geologists and petrologists recognize this text as a foundational contribution to the study of metasomatism and hydrothermal alteration. Readers frequently note the high level of technical and mathematical density required to fully grasp the author's theoretical framework.
