Provenance, Age, and Tectonic Settings of Rock Complexes (Transangarian Yenisey Ridge, East Siberia): Geochemical and Geochronological Evidence

The tectonic evolution of the Siberian Cratonic margins offers important clues for global paleogeographic reconstructions, particularly with regard to complex geological history Central Asia and Precambrian supercontinents Columbia/Nuna Rodinia its subsequent breakup opening Paleo-Asian Ocean. Here, we present an overview geochemical, petrological, geochronological data from a suite various rocks clarify age, settings, nature their protolith, emphasis on understanding Yenisey Ridge fold-and-thrust belt at western margin Craton. These pre-Grenville, Grenville, post-Grenville episodes regional crustal are correlated synchronous successions similar style along Arctic Nuna-Columbia support possible spatial proximity Siberia North Atlantic cratons (Laurentia Baltica) over long period ~1.4–0.55 Ga.
