The assembly of several continents into a single large supercontinent and its later dispersal into individual fragments is a key manifestation of plate tectonics. But the process also presents many open questions: What are the underlying mechanisms of assembly and break-up? Can we unravel the histories of the contributing orogenies? And what is the contribution of continent assembly to crustal growth? This session aims to draw the tectonic evolution of the orogenies that were formed in supercontinent assembly and their disintegration at supercontinent break-up including Arctic and Antarctic areas. We invite contributions that discuss the structural elements that were formed during the collisions and during break-up from a geological, geochemical, and geophysical perspective.

Original session TS8.2 titled "Supercontinent assembly and disintegration: Case studies from Rodinia, Gondwana and Pangea" has been merged with a session convened by Pierpaolo Guarnieri and Jaroslaw Majka titled "Basement-cover relationships in Orogenic Belts from Greenland to Svalbard: The Arctic gateway", hence a number of contributions will be focused on the geology of Arctic regions. Nevertheless, the main emphasis will be given to supercontinent assembly and disintegration processes and the tile of the TS8.2 session remains unchanged.
