Dear all,

Please consider submitting a contribution to the following session at EGU 2013 in Vienna, Austria, 7-12 April.

TS10.5/GMPV41

Structural, metamorphic and magmatic evolution of the margin of Baltica and Laurentia and other Mesoproterozoic orogens

Conveners:

Trond Slagstad and Giulio Viola, Geological Survey of Norway
Nick Roberts, NERC Isotope Geosciences Laboratory, British Geological Survey

Invited speakers:

Toby Rivers, Memorial University

Jenny Anderson, Geological Survey of Sweden

Eric Tohver, University of Western Australia

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 Mesoproterozoic orogens.
