 Abstract: A large set of recently acquired U-Pb zircon age and Nd isotope data is presented and discussed in terms of the geotectonic evolution of Sarmatia during the Rhyacian. It is shown that a large portion of continental crust within Sarmatia, including the East Sarmatian and Teteriv-Ingul orogens, was formed during the Rhyacian. Deposition of sedimentary rocks started at ca. 2.25-2.20 Ga and these rocks were metamorphosed and migmatized at 2115-2090 Ma. Extensive development of felsic and mafic igneous complexes at 2080-2030 Ma was likely related to the post-collisional extension with delamination of the lithospheric mantle. Metamorphic and magmatic events at ca. 2.1-2.0 Ga were linked to a collision between the Sarmatia and Volgo-Uralia segments of Baltica. Continued subduction along the northern margin of the assembled craton has eventually resulted in a collision with Fennoscandia at ca. 1.82 Ga.
