| description | There are complex of data about composition, age, isotopic parameters for granites from the Ufaley block, which is situated in the accretion zone on the boundary between the Urals and the East European platform. Granitoides mark the main stage of the geological structure evolution: from the intraplate rifting (episodes 1100-880, 570-533, 476-457 Ma) with full and partial rupture of the crust to the beginninf of orogenes (about 317 Ma) and collision (260-250 Ma). On the base of isotopic data we show that there is the substantial evolution of the source in time reflecting the increasing of part of sialic component in the source for granite formation. Maximal quantity of the granite impulses was fixed within the Ufaley block and it’s neighboring marginal structure - Bashkirian anticlinorium. This fact notes to involvement here the margin of East European platform to all episodes of tectonic-magmatic activity from the Riphean rifting to Paleozoic orogenesis which was maximal during the formation the own Uralian collision orogen. |
