Abstract

The paper presents the results of study of zircons of polymetamorphic and granitoid complexes of the Urals. The morphological features of the mineral characteristic of metamorphic and granitoid rocks are established. Morphotypes corresponding to the different physicochemical conditions of their formation and transformation of the host rocks have been identified. Geochronological data are obtained for individual morphotypes of zircons. Geochemical characteristics are established and a comparative analysis of the distribution of individual scattered elements in zircons is conducted, including an analysis of the Th / U ratio in zircons of polymetamorphic complexes and granitoids.
