The tectonic evolution of the continental margins of SW Baltica and SE Laurentia displays numerous large-scale similarities, from the Late Palaeoproterozoic to the Mesoproterozoic. This evolution is generally interpreted in terms of a long-lived active continental margin, the remnants of which are now preserved in the Grenville and Sveconorwegian Provinces of Canada and Norway/Sweden. Differences in timing and tectonic style nevertheless show that tectonic events cannot be correlated along the entire length of the orogen, and suggest a margin characterised by processes related to oceanic subduction, continental collision and strike-slip movement – varying in space and time – similar to some present-days margins.

We invite contributions that, by drawing upon structural, metamorphic, petrological and geochronological studies, can help refine our understanding of this orogeny. In addition, with the aim to compare and contrast different orogenic processes and tectonic evolutions, we invite contributions from other Mesoprotetozoic orogens.
