Description : The hypothesis that the cyclic amalgamation and breakup of supercontinents has existed for the past 2.5 Ga has a profound implications for the evolution of the Earth’s systems. The proposed special session is intended as a celebration of the career of Damian Nance, who was an integral part of the research team that initially proposed the existence of such a cycle more than 30 years ago. We are soliciting presentations which focus on topics and processes related to formation and breakup of supercontinents, the amalgamation of Pannotia/Gondwana, the generation and destruction of Paleozoic oceans, and the development of the Appalachian-Ouachitan-Caledonide-Variscan orogens. The session will be co-sponsored by IGCP 648 (Supercontinent Cycles and Global Geodynamics) and will draw a large international gathering to the conference to celebrate Damian as well as the advances in our understanding of supercontinents over the past 30-35 years. As an outcome of this special session, we will be soliciting contributions to a publication (venue to be decided) in Damian’s honour.
