Middle and Upper Ordovician carbon isotope chemostratigraphy in Baltoscandia: a correlation standard and clues to environmental history
The Baltoscandian epeiric sea was characterised by relatively slow but continuous
carbonate deposition from the Middle Ordovician up to the Silurian. Relatively good …
