The guidebook is dedicated to ultramafic-mafic intrusions, volcanic rocks and the world-class PGE-Cu-Ni sulfide deposits of the Noril’sk Province, Polar Siberia. The characteristics of geology, mineralogy and geochemistry of volcanic rocks and ore-bearing ultramafic-mafic intrusions are briefly outlined. The proposed excursion stops include inspection of the different volcanic and intrusive rocks, associated PGE-Cu-Ni sulfide ores from drill cores and bedrock outcrops. In addition, an open pit Medvezhy Ruchei and two mines (Oktyabrsky and Taimyrsky) collectively provide an overview of the Noril’sk-type intrusions and associated disseminated and massive PGE-Cu-Ni sulfide ores. The materials of the guidebook are of a broad interest for geologists, earth scientists and students.

The guidebook illustrates two distinct types of ore-bearing massifs within the 900-km-long Uralian Platinum Belt: the Nizhny Tagil clinopyroxenite-dunite massif and related platinum bedrock and placer deposits, and the Volkovsky gabbro massif comprising copper sulfide deposit with PGE mineralization. Structure of the Tagil zone and general characteristic of magmatism, questions of age and genetic models are briefly outlined. The proposed excursion stops include inspection of different ultramafic and mafic lithologies from natural bedrock outcrops and open-pits.The materials of the guidebook are of a broad interest for geologists, earth scientists and students.
