Dear All, Apologies for multiple postings. We would like to bring your attention to our session. We announce our upcoming session at JpGU-AGU Joint Meeting 2026 (24-29 May) at Makuhari, Japan and warmly invite you to contribute an abstract. Session information https://www.jpgu.org/meeting_e2026/sessionlist_en/detail/S-MP30.html Submission link (final deadline: 17 Feb.) https://www.jpgu.org/meeting_e2026/submission.php [S-MP30] Supercontinents and Crustal Evolution Supercontinent formation and dispersion has been enigmatic in the Earth's history. Eurasia is one such current supercontinent and incredible progress in the understanding of its geological evolution has been achieved in the past decade. Earlier supercontinents in the Earth's history such as Gondwana (0.5 Ga), Rodinia (1.0 Ga), Columbia/Nuna (2.0 Ga), Kenorland (2.5 Ga) and Vaalbara (3.1 Ga), have been the focus of several studies, however limited information on older supercontinents has restricted an understanding their tectonic evolution. Several important unsolved issues remain, such as how, when and where these supercontinents formed and how long they remained as such before breaking apart. Additional questions arise on the processes that triggered the fragmentation and unification of continents. In this session, we invite authors around the world to present original new data as well as review results on the continental scale crustal processes and tectonic evolution that are associated with supercontinent formation events in Earth's history. The well-studied Eurasia and Gondwana supercontinents are of particular focus. Topics of interest include, but not restricted to, extremes in metamorphism, P-T-D-t evolution, magmatism, and the role of fluids. We hope to provide a platform for scientific discussions that will enlighten our understanding of the physical and chemical processes in the continental crust that records episodes of orogenesis that contributed to the formation and evolution of supercontinents. We look forward to seeing you in Makuhari!
