The paper considers processes of ore formation. This concerns complex dynamic natural objects, depending on polygenic geological phenomena, mutually interacting and forming a single mineral formation environment. Development of ore-forming systems is connected not only with the natural evolution of thermodynamic parameters, but also with physical-chemical properties and composition of ore-bearing deposits, state and character of manifestation of tectonic structures, such as field strength, degree of tectonic trans...

The paper provides comparative characteristics geodynamic situations and of related intrusive series. Discussed are cases of alternation of such granitoids in time, their connection in space and relation to collisional processes. I-granites form extended gabbro-diorite-granodiorite-sodium and potassium-sodium granite series with gradual increase of the role of silica and potassium in the final products. Differences in the petrochemical composition of pre- and late collision of I-granites are conditioned by the sub...
