AGE OF GRANITOIDS IN THE MAN'KHAMBO AND IL'YAIZ PLUTONS, THE NORTHERN URALS: U-PB DATA

Abstract

The Man’khambo and Il’yaiz plutons are situated in the northern Urals at the main divide of the Urals (basins of Shchugor, Ilych, and Severnaya Sos’va rivers). These plutons cut the Upper Riphean–Vendian country rocks [1, 2] and, along with the latter ones, belong to Preuralides of the Central Ural Uplift. The Man’khambo and Il’yaiz plutons cover about 700 and 200 km2, respectively, and are the largest granitoid bodies of this tectonic unit. The plutons are localized in the core of the Man’khambo Anticlinorium, a part of the Lyapin–Kutim Meganticlinorium of the Central Ural Uplift.
