The Cambro-Silurian carbonate rocks of the Oslo Region are usually calcitic (Holtedahl 1912), and dolomites have not been reported. During a student excursion in 1963 the authors found a sediment from the Middle Ordovician Mjøsa Limestone which from its macroscopic lithology was suspected to be a dolomitic rock. This was confirmed by laboratory studies.
