New Evidence for Grenville Events on the Western Margin of the Siberian Craton: The Example of the Garevka Metamorphic Complex in the Transangarian Yenisei Ridge

摘要

Reconstruction of geological history of the Yenisei Ridge, which is an accretion-collisional orogen on the western margin of the Siberian Craton, is important not only for understanding the tectonic evolution of mobile belts surrounding ancient cratons, but for the solution of the problem of involving of the Siberian Craton in the composition of the Rodinia superconti-nent as well. According to the existing concepts, this supercontinent appeared at the boundary between the Meso- and Neoproterozoic as a result of the Grenville orogeny.
