My current research is concentrated on the formation and evolution of the Precambrian East European Craton/”Baltica”, a key component of one-time supercontinents like Mesoproterozoic Rodinia and Palaeoproterozoic Columbia/Nuna.
The basis of this research are my previous findings, which demonstrated that the East European Craton (EEC) is not a mosaic of minor Archaean and Proterozoic rock units as previously assumed. Rather, it was formed between ca. 2.1 and 1.75 Ga by the gradual collision of the three large crustal segments/continental blocks Fennoscandia, Sarmatia and Volgo-Uralia. As indicated by palaeomagnetic data, these had their own separate pre-histories of development and even belonged to different lithospheric plates. Subsequently, their Palaeoproterozoic collisional sutures were outlined by trans-cratonic Mesoproterozoic rifts, which still influence the present environment.
Virtually all of my research on the EEC/Baltica is conducted within internationally integrated geological-geophysical studies. These range from global-scale modelling to the important trans-Baltic correlation of the crystalline basement in the East-European platform area with the Baltic shield in Scandinavia in cooperation with colleagues from Belarus, Lithuania, Poland, Russia, and Ukraine. A major recent enterprise, where some of the results are still in the process of publishing, was “EUROBRIDGE” project of the EUROPROBE-Programme, of which I was international leader.
Conversely, the results of EEC research are important in world-wide modelling. Since 2001, I have thus been international co-leader of the global project “Assembly and Break-up of Rodinia”, which has been focused on testing the Rodinia supercontinent hypothesis. At this moment, the Rodinia database is part of IGCP-project 509 “Palaeoproterozoic Supercontinents and Global Evolution”.
Another instance of interaction between global Precambrian reconstructions and study of the EEC and Fennoscandia is the case of the Danopolonian orogeny, which is manifested by 1.50-1.45 Ga magmatism, metamorphism and deformation in southern Sweden, on Bornholm, and in the Baltic-Belarus region. Apparently, it resulted from collision of the EEC with another continental block (Proto-Amazonia?) and attendant plate reorganization. Subsequently, deformation zones formed during the Danopolonian were active throughout the Phanerozoic and even recently, and are now being studied by our research network within the Visby Programme of the Swedish Institute.
One more aspect of my on-going research is interpretation of geophysical data from Ukraine in terms of mantle heterogeneity, magmatism, and layering of the upper lithosphere.
