Zaccarini F.; Garuti G.; Pushkarev E.V.; Fershtater G.B. (2004)We have investigated two subeconomic bodies of chromitite in the Nurali Iherzolite-gabbro complex, in the southern Urals, Russia, with regard to the composition of the chromian spinel and the distribution and mineralogy ...

Fershtater G.B.; Kholodnov V.V.; Borodina N.S. (2001)Principal compositional features of Riphean gabbroids and associated titanomagnetite deposits on the western slope of the Urals are generally related to P-T conditions and the fluid regime of their formation. At low fluid ...

Fershtater G.B.; Bea F.; Montero M.P.; Scarrow J. (2004)Hornblende gabbroids, which are widespread in the Urals, are products of hydrous basic magmatism, mainly subduction-related. Two groups of these rocks are recognized: (1) pre-Middle Devonian (older than 390 Ma) gabbroic ...

Fershtater G.B.; Pushkarev Y.V. (1992)Tylaites - feldspathic olivine clinopyroxenites from the Tagil'skiy dunite-clinopyroxenite massif in the platinum-bearing belt of the Urals - are of magmatic origin. They are composed of phenocrysts of zonal clinopyroxene, ...

Bea F.; Fershtater G.B.; Montero P.; Whitehouse M.; Levin V.Y.; Scarrow J.H.; Austrheim H.; Pushkariev E.V. (2001)The presence of zircons of crustal origin in the dunites of Kytlym, a subduction-related concentrically zoned dunite–clinopyroxenite–gabbro massif of the Urals Platinum-Bearing Belt, may provide the first direct evidence ...

Fershtater G.B.; Bea F.; Borodina N.S.; Zin'kova E.A.; Montero P.; Shagalov E.S. (2002)The most intense subduction-related anatexis in the Urals occured in the late Early Carboniferous (340-320 Ma). It is characterized by high water saturation (PH2O = 0.7 1.OPtot) of the generated melts, caused by additional ...

Fershtater G.B. (2003)In the Silurian-Carboniferous (440-330 Ma), the Urals was involved in suprasubduction magmatism. The following subduction-related intrusive magmatites are recognized here: 1. Volcanic, mainly high-level complexes including: ...
