"Geología de Yacimientos Minerales" by V.I. Smirnov is a seminal, comprehensive text defining the Soviet school of economic geology through a genetic classification of mineral deposits. The work systematically categorizes deposits into endogenous, exogenous, and metamorphogenic groups based on their geological origin. For a detailed summary of Smirnov's classification, see this document on Concentración mecánica por gravedad en ríos o costas
