Аннотация: This U–Pb zircon geochronological study using TIMS and SHRIMP dating reveals new insights into the magmatic and metamorphic evolution of the Siberian Craton. Granulites, granites and one migmatite substantiate a multistage history. For the granulites an Archean protolith (3.4 Ga) is documented, followed by a first granulite formation at 2.6 Ga. In the Palaeoproterozoic a migmatisation event at 2.0 Ga and two stages of granulitisation and granite emplacement at 1.88 Ga and 1.85 Ga are detected. The latter event (1.85 Ga) is interpreted to mark the final consolidation of the Siberian Craton. Therefore this part of the craton was protected from younger overprints during the assembly of Rodinia in the Mesoproterozoic.
