U/Pb Age of detrital zircons from sandstones of the upper emsian diamond takaty formation of the Western Urals
The first results of U/Pb (LA-ICP-MS) dating of detrital zircons from quartz sandstones of the Devonian Takaty Formation are presented. The obtained ages span a range from 1857.5 ± 53.8 to 3054.0 ± ± 48.0 Ma. The vast «gap» (~1.5 Ga) between sedimentary age of Takaty Formation and the age of the you...

Summary: | The first results of U/Pb (LA-ICP-MS) dating of detrital zircons from quartz sandstones of the Devonian Takaty Formation are presented. The obtained ages span a range from 1857.5 ± 53.8 to 3054.0 ± ± 48.0 Ma. The vast «gap» (~1.5 Ga) between sedimentary age of Takaty Formation and the age of the youngest zircon grain is fixed. A comparison of known ages of crystalline complexes from the Volga-Uralian part of East-European Platform with obtained ages of detrital zircons from Takaty Formation supports the «Volgo-Uralian» origin of the zircons. This implies the existence of a previously unknown stage of kimberlitic magmatism, much more ancient than the stage of kimberlitic magmatism formed diamonds in Arkhangelsk and Timan provinces. |
