We present structural data for metaterrigenous rocks and metagranites from tectonic units of southeastern part of the Tatarka-Ishimba suture zone (Yenisei Ridge). Fold-thrust and strike-slip deformations were caused by the Central Angara - Siberian Craton oblique collision in the late Tonian Period. New 40Ar/39Ar geochronological data from metagranites shows a superposed tectonothermal event, which is likely associated with an early magmatic stage of the Tatarka active continental margin complex in the Cryogenian Period
