Abstract

PALYNOLOGICAL STRATIGRAPHY OF BEDS AT THE JURASSIC - CRETACEOUS BOUNDARY IN THE KUJAWY AREAThe palynological examinations of the Lower Cretaceous in the Polish Lowland area, Rogoźno region, were begun in 1960. Both lithology and stratigraphy of the profiles, which served as a base for the present elaboration, were made and macro-faunistically elaborated by S.Marek (1960, 1963). Microfauna was determined by W. Bielecka and J. Sztejn. The study made on the basis of the presence of sporomorphus allowed to construct the first type stratigraphical scheme for the Lower Cretaceous (Infravalanginian, Valanginian and Hauterivian) and for the adjacent Purbeckian deposits (J. Mamczar, 1964).
