Abstract

It is shown that post-island-arc intrusive magmatism of the West-Magnitogorsk Zone embraced the time from Late Devonian to Late Carbon. The new systematization scheme for all variety of intrusive formations is proposed based on the new geological-geochemical data and evolutionary-genetic reconstructions. It presents four discrete intrusive series: 1) gabbro-norite-diorite, 2) gabbro-diorite-granite, 3) peridotite-gabbro-diorite-granite, 4) lamprophyre-dolerite. Each series is characterized by original properties of the body’s morphology and rocks petrography, mineralogy and geochemistry.
