1. Milankovitch Cycles in Chalks, Danish North Sea, Detected by Use of Magnetic Susceptibility
Sammanfattning : Subdivision of the Maastrichtian chalk from the Danish North Sea has proven to be difficult because of the homogenous composition and appearance. A high-resolution subdivision of the chalk yields new information and better understanding of the depositional environment along with the possibility of an advantageous correlation. LÄS MER
2. Dinoflagellate studies of the Upper Maastrichtian and Danian in southern Scandinavia
Sammanfattning : Three Swedish borehole cores and three Danish outcrop sections, spanning the Upper Maastrichtian and Danian, have been analyzed for dinoflagellates. Variations in the relative abundances of certain dinoflagellate species have been used to establish a quantitatively defined, high-resolution zonation for the Upper Maastrichtian of southern Scandinavia.

3. Mid-Cretaceous ostracoda of Algeria and a review of Maastrichtian-Paleocene ostracoda of the South Atlantic
Sammanfattning : .... LÄS MER
4. Magnetic properties of the Limhamn rocks : a paleomagnetic, rock magnetic and paleoenvironmental study of the Maastrichtian chalk and the Danian limstones in Limhamn, Scania, southern Sweden
Sammanfattning : .... LÄS MER
5. Jurassic and Early Cretaceous selachians - focus on southern Scandinavia
Sammanfattning : The Jurassic and Early Cretaceous selachian faunas of Scania (Skåne), southern Sweden and the island of Bornholm (Denmark) have been investigated. Three Early Jurassic shark tooth assemblages have been recorded and investigated, one from Hettangian strata and the other two from Pliensbachian sediments. LÄS MER
