| Abstract: | U-Pb dating of zircons (SHRIMP-II) has been performed for the first time for granites, granodiorites, and synplutonic granodiorite
and melanodiorite bodies of the Shartash and Shabry massifs in the Middle Urals. The time of the formation of the massifs
is 300–306 Ma, which is 25 Ma younger than the previous estimates. The age data obtained are in line with the time of the
formation of the adamellite-granite series of the Verkhisetsk Batholite (the master sample of tonalite-granodiorite-granite
magmatism in the Middle Urals), the series of which is petrochemically close to the rocks of the massifs. |
