PETROLOGY, GEODYNAMICS, AND ORE POTENTIAL OF MAGMATIC FORMATIONS - REVIEW OF RESULTS AND PROSPECTS OF FORMATIONAL ANALYSIS

The Russian theory of magmatic formations intimately involved with the school of thought of Academician Yu. A. Kuznetsov is a magma-tectonic concept based on a modern approach relating composition character of igneous rocks to geodynamic conditions of their formation. An importan t result of the evolution of formational analysis of magmatism was tec tonomagmatic typification and detailed classification of magmatic comp lexes according to composition. As this school of thought evolved, for mational petrology advanced its frontiers taking into account not only physicochemical parameters but also geological (tectonic, geodynamic, evolutional) factors; present-day petrology of magmatic formations fo llows the same way. Concepts of magmatic formations provided a base of Russian magmatic metallogeny; a similar approach with recognition of tectonical or geodynamical types of magmatism and identification of th eir metallogenic specialization is now acceptable in the world's pract ice. The formational approach to study of magmatic complexes seems to be promising in the further development of the problems mentioned and in geological survey and searching for mineral resources.
