Geochemical features and differences in condition of formation and location of gabbro-granite complexes from the large riftogenic structures of the Sourthern Urals (Middle Rifean - Kuvash-Mashak and Early Carboniferous - Magnitogorsk) were placed. They characterize the metallogenic specialization and types of associated magmatic (Fe, Ti) and metasomatic skarn-mametite ores, which have an industrial importance.
