TS10.5Rifting, assembly, and collisional processes in the Caledonides: the first step on the way to Pangea
|Convener: F. Corfu | Co-Convener: H. Stunitz|
The Caledonian orogen, today exposed in Svalbard, Scandinavia, Greenland, the British Isles and North America, is an ideal laboratory to study deep-seated processes related to continental collision and subsequent continental break up. This session aims at bringing together researchers from different fields including structural geology, geochronology, metamorphic and magmatic petrology, geochemistry, thermochronology, sedimentology, geophysics and modelling, in order to discuss recent advances in the understanding of the Caledonian orogen. Topics to discuss may include: (i) tectonostratigraphy and structural evolution of large-scale nappe systems, (ii) timing of rifting, burial, metamorphism, and exhumation of tectonic units, (iii) origin and paleogeography of tectonic units, (iv) the distribution and age of Proterozoic to Paleozoic sedimentary basins within the orogen, (v) timing and mode of magmatism within the orogen, (vi) models for nappe-stacking and exhumation mechanisms, (vii) post-orogenic collapse
Invited presentations by Cees Van Staal and Torgeir Andersen will provide a modern perspective on Caledonian-Appalachian tectonics.
