The paper presents the main results of isotopic-geochronological and mineralogical-geochemical studies at the territory of the Ilmeny State Reserve over 2010–2020. A summarized age scheme is given for various rock types of the Ilmenogorsk polymetamorphic complex. The textural-structural features of milonites and main directions of metasomatic processes in the rocks of the complex are shown.
