Geosciences Working Group

lecturer: Harald Rohe
Gotland, Sweden`s largest island and a popular vacation destination in the Baltic Sea, also hosts a special geology: tropical coral reefs from the Lower and Middle Silurian (435 - 423 million years before present), which are excellently preserved due to only minor subsidence and largely missing tectonic stress and give a unique impression of shelf ecosystems at the edge of the Baltic. The lecture introduces the geology, shows the evolution of the carbonate facies during the Silurian and places it into paleoclimatic model concepts based on geochemical measurements on brachiopods.
