The development of new approaches to the study of the regularities of the chemical composition of rocks helps to decipher the physical and chemical processes occurring in the lithosphere and to develop the models of genesis and refine the technology of prospecting and extraction of minerals. Factor analysis was used to process data on the chemical composition and content of impurity elements in rocks. With the use of experimental studies and guides of various authors, the interpretation of internal and external factors of the formation of rocks and the mineralization associated with them is carried out. It was found that the formation of rocks is influenced by such external factors as the redox potential and acidity of the environment, and an internal factor such as the energy of half-reactions of the reduction of chemical elements. The analysis results revealed two geochemical associations: 1) Fe-Co-As-Ti-V-P-Ag-Au; 2) CaO-MgO-CO2-H2O-Pd-Pt-Au-Ag. The first association of elements was found in the rocks of the Tyrkanda tectonic zone and can be related with metabasites in complex dikes. The second association of elements was found in the rocks of the Nimnyr terrane and can be related with metamorphosed fragments of layered intrusions, or with metasomatism of crystalline schists by components of carbonate rocks.
