摘要:

Lower Jurassic sediments from the Gantofta-Katslösa area in Scania (Skåne) are described lithologically and biostratigraphically. The sediments strike mainly N 45°E and have a main dip between 15° and 25° to the SE. Two strike-slip faults were observed in the area. They have a strike of ca. N 65°E and N-S. Their dips are 35° to the NW.

摘要:

New data are given on the Swedish Upper Jurassic and Lower Cretaceous sedimentary sequences, including unpublished subsurface documentation from the hydrocarbon prospecting, released for the IGCP Project Tornquist, as well as results from current mapping operations. A brief review is given on the Swedish Upper Jurassic and Lower Cretaceous sedimentary deposits, which are restricted to the southwestern margin of the East European Platform. Their distribution, depositional environments, lithology and stratigraphical representation are discussed. In terms of chronostratigraphy, foraminifers and ostracodes establish the presence of the Oxfordian, Kimmeridgian, and Portlandian Stages of the Upper Jurassic, and the Valanginian, Hauterivian, Barremian, Aptian, and Albian Stages in the marine Lower Cretaceous. A stratigraphy of Jurassic-Cretaceous transitional beds, which probably include Portlandian, Berriasian, and Valanginian non-marine strata, has yet to be established; consequently, the Jurassic-Cretaceous boundary in Sweden is still undefined. Swedish Upper Jurassic lithostratigraphical units are defined, whereas a corresponding subdivision of the Lower Cretaceous remains to be established.

摘要:

A stratigraphical scheme for a dinoflagellate zonation of the Upper Maastrichtian and Danian of southern Scandinavia is proposed. Three Upper Maastrichtian and four Danian biozones are differentiated. Central sections of the Danish Embayment in northwestern Denmark differ profoundly from marginal sections in eastern Denmark and Scania where the Maastrichtian-Danian boundary, strata are shown to be more condensed. The distribution patterns of the dinoflagellate assemblages have been statistically tested and the results presented herein clearly indicate that the great variability of these assemblages is not random.
