Abstract

The thematic set of papers in this issue of the Proceedings , ‘The Chalk of the Northern Province’, arose from a symposium of the same name at the University of Hull, 10–13 September 2015. The meeting was organized jointly by the Hull Geological Society, the Yorkshire Geological Society and the Department of Geography and Earth Sciences at the University of Hull, and was supported by the Stratigraphy Commission of the Geological Society of London. The seven papers published herein represent a cross-section of the presentations enjoyed by attendees. In a broad review, Mitchell evaluates the litho- and biostratigraphy of the Chalk in the Northern Province. Six formations are recognized, although the Rowe Formation (Campanian) is hidden by drift. Unlike the Southern Province, where the Chalk rests on the Gault Clay Formation, that of the Northern Province sits on the Hunstanton Formation (=Red Chalk). The Chalk of the Northern Province is also less flint-rich and is harder with more stylolites than that of the Southern Province. Its deposition was controlled by a series of structural highs. Particular attention is paid to the internationally important sequence at Speeton with …

In the distinctly different Chalk of Lincolnshire, Yorkshire and parts of north Norfolk, borehole geophysical log profiles have been matched with formational subdivisions for large parts of the Chalk Group, but the youngest and thickest part of the succession at outcrop, the marlstone-rich and largely flint-free Flamborough Chalk Formation, has not been characterized geophysically hitherto

Summary

Introduction

The thematic set of papers in this issue of the Proceedings, ‘The Chalk of the Northern Province’, arose from a symposium of the same name at the University of Hull, 10–13 September 2015. Mitchell evaluates the litho- and biostratigraphy of the Chalk in the Northern Province. This review ably supports the other papers in this volume, including as it does comprehensive discussion of stage boundaries and fossil zonation of the Chalks of this Province.
