Abstract
A long-standing problem in the Ordovician stratigraphy of south-eastern Norway has been to the relations between the Mjosa Formation in the Lake Mjosa region and coeval strata in the Oslo region. The recent discovery of the globally distributed Guttenberg delta(13)C excursion (Guttenberg Isotopic Carbon Excursion) in the Mjosa region provided the impetus to search for this excellent chemostratigraphic marker in the classical Oslo region succession, where it was found in the Frognerkilen Formation. Another positive delta(13)C excursion, which we identify as the Kope excursion, was discovered in the Solvang Formation. The new data show that the lower Katian delta(13)C chemostratigraphy in the Oslo region is closely similar to that from... (More)
A long-standing problem in the Ordovician stratigraphy of south-eastern Norway has been to the relations between the Mjosa Formation in the Lake Mjosa region and coeval strata in the Oslo region. The recent discovery of the globally distributed Guttenberg delta(13)C excursion (Guttenberg Isotopic Carbon Excursion) in the Mjosa region provided the impetus to search for this excellent chemostratigraphic marker in the classical Oslo region succession, where it was found in the Frognerkilen Formation. Another positive delta(13)C excursion, which we identify as the Kope excursion, was discovered in the Solvang Formation. The new data show that the lower Katian delta(13)C chemostratigraphy in the Oslo region is closely similar to that from south-eastern and southern Estonia. This permits detailed correlations across Baltoscandia, which are useful for recognising the Baltic stage boundaries in the Oslo region succession. Both the Lake Mjosa and Oslo regions study successions can be chemostratigraphically correlated with those in North America and eastern Asia. The newly established stratigraphic relations in the Oslo region are also used for a re-assessment of lower Katian local and eustatic sea-level changes. (Less)
