Abstract
Granulites, granites and one migmatite substantiate a multistage history. For the granulites an Archean protolith (3.4Â Ga) is documented, followed by a first granulite formation at 2.6Â Ga. In the Palaeoproterozoic a migmatisation event at 2.0Â Ga and two stages of granulitisation and granite emplacement at 1.88Â Ga and 1.85Â Ga are detected. The latter event (1.85Â 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.
