Abstract

A short description of geological structure of the Ilyinovsky metamorphic complex of the Transuralian Uplift is given, based on a study of a garnet-biotite paragenesis, widely developed among paragneisses and diaphtorites. Two stages of transformations of rocks are established. In the Early Proterozoic (Paleoproterozoic) time the sedimentary deposits undergone a metamorphism of amphibolite (cummingtonite-amphibolite) facies under temperatures 530-580°С and pressure 3,0-3,1 kbar , and then in the Late Riphean time, in connection with a structural reorganization of the Southern Urals – in conditions of the epidote-amphibolite facies (T=500-560°С, P=5,4-6,0 kbar).
