Field trip 1 Ultramafic-mafic intrusions, volcanic rocks and PGE-Cu-Ni deposits of the Noril sk Province, Polar Siberia Duration 8 days + travels Tour starts August 31/07/2014 in Noril sk, the end 7/08/2014 Period: pre-symposium Maximum number of participants: 30. Accommodation: Hotel in Noril sk Estimated cost is 1500 Euro without price on flight tickets to Noril sk and from Noril sk to Yekaterinburg. Dear participants of the Noril sk geological excursion, we are planning to cover your expenses for accommodation at the hotels in Yekaterinburg during 12th Platinum Symposium from your field trip fees. Additional information will be provided for you personally. The field trip will be organized and held by Zapolyarny Branch (Polar Branch), Open Joint Stock Company MMC "Norilsk Nickel". Evgeny Parievsky - responsible person. Scientific leaders: Sergey Sluzhenikin (IGEM RAS) sluzh@igem.ru and Nadya Krivolutskaya (GEOKHI RAS), e-mail: nakriv@mail.ru Fig. 1. Noril sk district. Flood basalt deposits A striking feature of the Norilsk deposits is the high-degree of concentration of sulphidehosted Cu and Ni as well as PGE that is unique and unknown elsewhere in the world. Despite decades of researches, many questions on the origin of these deposits are still not resolved. The disputable aspects include: compositions of parental magmas and relationship between intrusions and host terrigenous and volcanic rocks; origin of geochemically contrasting ore-bearing and barren intrusive complexes; role and conditions of contamination at formation of massive sulphide ores; mechanism of high-grade PGE mineralization in the complex PGE-Cu-Ni and PGE low-sulphide types of ores. The proposed excursions will give an opportunity to consider a wide spectrum of geological facts, to appreciate the different points of view and to develop your own ideas on the origin of this unique mineralization. We shall visit the mines of the Norilsk Nickel Company, look at cores of the exploration boreholes through the intrusions and examine the sequences of host sedimentary rocks and flood basalts (fig. 1). The zonal transition from pyrrhotite-rich ore through cubanite ones to talnakhite and mooihoekite varieties can be seen in the massive pyrrhotite and high-grade cupriferous orebodies of the Oktyabrsk underground mine. The textural variability of breccia-like ores (Fig. 2) and their
relationships with massive ore can be also observed there. The details of massive pyrrhotite and veinlet-disseminated orebodies in the contact of the Kharaelakh intrusion can be seen in the Taimyr underground mine. The orebody is composed of two ore varieties coarse-grained reticulatetextured ore and fine-grained magnetite-rich ore. The direct contact between disseminated sulphide mineralization in picritic and taxitic gabbrodolerite at the base of the Talnakh intrusion and mineralization in metamorphosed and metasomatised sedimentary rocks can be observed in the Komsomolsky underground mine (Fig. 3). Sedimentary rocks are represented by terrigenous rocks of the С2 P2 Tunguska Group and Devonian carbonates. Fig. 2. Breccia-like ores of the Oktyabrsk deposit, the Oktyabrsk mine. The section of the Norilsk-I intrusion with disseminated orebodies in the lower differentiates can be observed in the Medvezhy Ruchei (Bear Creek) open pit. The complete layered sequence from olivine-free to picritic gabbrodolerites with PGE-Cu-Ni ore in the lower part (Fig. 4) and lowsulphide PGE ore in the upper endocontact zone (Fig. 5) should be available for observation.

Talnakh deposit The exploration cores of the Talnakh, Kharaelakh and Noril sk-i intrusions and related PGE- Cu-Ni and PGE ores will be available in the Norilskgeology coreyard.
