Description

Cambrosilurian succession of the Oslo Region including some insights on Caledonian and Permian deformation.

The island of Hovedøya is only 5 minutes sailing from the Oslo harbor and the Askerhus castle. Mooring on the northern corner, delegates will walk across the southern part of the island, focusing on three uppermost Ordovician formations: Skogerholmen, Husbergøya and Langøyene. Along the walk, the group will pass the ruins of a Cistercian monastery dating back to 1147 which was destroyed after the reformation in Norway in 1536.

We will have lunch at the café by the monastary. Afterwards we will look at the transition between Ordovician and Silurian systems, Silurian strata being exposed in the southeastern part of the Island.

The explanations given by the guides will include some information on the formation of nodules limestones and their inferred significance as paleo-climate indicators. The geological development of the Oslo Region will be discussed, with focus on its evidence for tectonic inheritance and plate tectonic palaeo-climate interaction.
