Since the Neoproterozoic breakup of the supercontinent Rodinia, continental fragments episodically rifted from their original location and systematically drifted towards more northerly positions, culminating in the Late Palaeozoic amalgamation of the supercontinent Pangaea. In this session we focus on the processes responsible for the transportation of terranes from Gondwana to the northern continental masses (Baltica, Laurentia, and later Laurussia) before, during and after the collision between Laurussia and Gondwana and the amalgamation of Pangaea. We welcome multi-disciplinary (tectonics, geodynamics, basin analysis, palaeomagnetism, palaeogeography, plate reconstruction, etc.) contributions dealing with i) the geodynamic evolution (rift-drift-accretion) of terranes such as Ganderia, Avalonia, Carolinia, Meguma, Armorica, Moesia, North China, South China, etc., ii) the fate of intervening oceans (Iapetus, Rheic, Palaeotethys, Neotethys, etc.) and iii) the geodynamic drivers of their respective evolutions.
