SUMMARY To supplement the recent documentation of the stratigraphy of the Ferriby, Welton, Burnham and Flamborough Chalk formations by Whitham, a study of the nannofloras of this region was undertaken, allowing correlation between the lithostratigraphical units, the macrofossil zones and the recently revised standard nannofossil zonation scheme for the Upper Cretaceous. Attention is draw to the sequence of integrated nannofossil and macrofossil events around the stage boundaries, and some prelim...

Results from a detailed palaeomagnetic study of the Late Cretaceous sequences of Culver Cliff and Scratchell's Bay (Isle of Wight) and Seaford Head, East Sussex are presented. The sections range in age from Latest Turonian to early Late Campanian and consist of white chalk with flints. Hand samples and large volume rock cores have been collected. Both thermal and AF demagnetisation have been used to remove magnetic overprints. Measurements have been carried out using a CCL 'discrete sample' and ...

Abstract Recognition of the Campanian stage on the Brazilian Continental Margin, using calcareous nannofossils, has been historically problematic. This paper constitutes an overview of earlier works, showing how nannofossil biostratigraphic ideas have evolved since Troelsen & Quadros provided the first biozonation of this region in 1971. Recent studied have provided data which have helped to clarify these apparent biostratigraphic problems, and allows this region to be placed in a global biostra...

Abstract The Second International Symposium on Cretaceous stage boundaries held in Brussels from September 8-14 1995 reached a preliminary agreement on the definition of the base of the Cenomanian stage as the first occurrence of the planktonic foraminiferan Rotalipora globotruncanoides Sigal, with a section at Mont Risou near Rosans, Drome, SE France as the global reference section, Sigal, with a section at Mont Risou near Rosans, Drome, SE France as the global reference section, where the firs...

Review of biostratigraphical evidence from different regions shows that criteria used by workers on various marine fossil groups to define the Santonian-Campanian boundary differ considerably in relative age and position. Probably the most widely recognizable of these criteria is the extinction of the distinctive crinoid Marsupites testudinarius (North America, Europe, Asia, north Africa, Australia), which, coincides exactly with two separate definitions of the boundary - appearances of the ammo...

De quelques charbonnages du Limbourg belge (Houthalen et ZolderVoort) une faunule d'ammonites, belemnites et inocerames a ete etudiee. Les nannofossiles des echantillons d'ammonites ont ete identifies. L'assemblage est d'âge Santonien moyen (superieur) a superieur et peut ainsi etre compare a la «Craie de Lonzee» (province de Namur, Belgique) et a la Formation d'Aix-la-Chapelle de la region d'Aix-laChapelle - Vaals (SE des Pays-Bas et Allemagne)

Marine 87Sr/86Sr decreases from 0.70775 in the Cenomanian to 0.70730 in the middle Turonian before increasing in a near-linear manner to >0.70775 in the early Maastrichtian. This variation has been defined using samples from the English Chalk that are closely integrated with the macrofossil and microfossil biostratigraphy of northwestern Europe. With this new isotope curve a stratigraphic resolution is attainable in correlation that is typically ±0.8 Ma for the Santonian and Campanian stages. Is...
