Poster sessions are particularly prominent at academic conferences. Posters are usually one frame of a powerpoint (or similar) presentation and are represented at full resolution to make them zoomable.
Crustal evolution and geodynamic setting of the Sefwi Greenstone Belt, WAC. The Palaeoproterozoic West African Craton (2.25 - 2.07 Ga) represents one of the youngest, large provinces of juvenile crust on Earth. It displays lithological and architectural similarities to a number
of late Archean Provinces, including the Abitibi-Opatica terrane, Superior Province and Karelian and Kola cratons of the Fennoscandian Shield. Forming just after the Archean-Palaeoproterozoic transition, the magmatic evolution and geodynamic setting of juvenile crust formation of the WAC continues to stimulate scientific debate.
