Summary: One of the most expanded upper Campanian-Maastrichtian successions worldwide has been cored in a series of boreholes in eastern Denmark. A high-resolution holostratigraphic analysis of this part of the Chalk Group has been undertaken on these cores, notably Stevns-1, in order to provide a record of changes in chalk facies, water depths and sea-water temperatures. Combined lithological data, a suite of petrophysical logs including gamma ray (GR) logs, nannofossil and dinoflagellate palaeontology, stable carbon isotopes, seismic reflection and refraction sections form the basis for the definition of two new formations and six members, three of which are new, and for recognition of Boreal nannofossil subzones UC15eBP to UC20dBP. The upper Campanian-lowermost Maastrichtian Mandehoved Formation is subdivided into the Flagbanke and Boesdal Members and the Maastrichtian Mons Klint Formation is subdivided into the Hvidskud, Rordal, Sigerslev, Kjolby Gaard Marl and Hojerup Members. The Boesdal and Rordal Members show high GR values and a pronounced chalk-marl cyclicity. The Rordal and the thin Kjolby Gaard Marl Members have a regional distribution and can be traced over most of the Danish Basin, whereas the Hojerup Member is restricted to the easternmost part of Sjaelland. The other members consist of rather featureless white chalk. Abstract Copyright (2013) Elsevier, B.V.
