“…It explains why this new scheme was introduced and describes how the new chalk formations are recognised and geologically surveyed in the field. It complements and refines the initial account by Bristow et al (1997), which was based largely on the findings of field surveys in Dorset and Sussex, and which noted that the 'lateral continuity of mappable features and their relationship to lithostratigraphy will continue to be tested as mapping extends …'.…”

“…This led to the development of a generalised lithostratigraphic scheme (Bristow et al, 1997), following in particular the work of Mortimore (1986) and of Bristow et al (1995), that has been refined and ratified by the Geological Society Stratigraphical Commission (Hopson, 2005; Table 1). Subsequent BGS mapping has shown that this scheme is valid throughout southern England, and to date it has been applied to most of the Chalk outcrop south of the Wash.…”

“…An understanding of the methods used to construct maps of the Chalk can provide a better appreciation of the meaning, uses and limitations of those maps. This paper contrasts historical practice in mapping the Chalk with the application of a lithostratigraphic scheme developed during the 1990s (Bristow et al, 1997;Mortimore et al, 2001;Hopson, 2005; Table 1) and since used widely in southern and eastern England by the British Geological Survey (BGS). It explains why this new scheme was introduced and describes how the new chalk formations are recognised and geologically surveyed in the field.…”

Abstract:The modern Chalk Group lithostratigraphy divides the Chalk of southern England into nine formations, each with a characteristic lithological assemblage. It is more useful than the traditional subdivision into Lower Chalk, Middle Chalk and Upper Chalk because it can be applied more consistently over a wider area, it provides a better indication of lithological variation, it allows the recognition of more tectonic structures and it is thus more useful for practical application in engineering geology and hydrogeology.The process of surveying the Chalk that has been developed by the British Geological Survey over the past two decades is an empirical modification of the traditional methods used for detailed geological survey of sedimentary sequences in other parts of the United Kingdom. Each Chalk formation is closely associated with characteristic landforms, allowing them to be mapped with reasonable consistency and accuracy in largely unexposed ground and through built-up areas. This association of landform and lithostratigraphy reflects the response to weathering (and other surface processes) of relatively subtle variations in bulk lithological assemblage, rather than of individual beds of contrasting lithology.

“…9). The Melbury Sandstone is equivalent to the Glauconitic Marl at the base of the Chalk Group in southeastern England (Bristow et al, 1997). Like the Melbury Sandstone, the Glauconitic Marl is immediately underlain by an erosion surface, but unlike the situation at Eggardon, this erosion surface is also coincident with a clearly visible facies change.…”

“…These formed a foundation on which to build the investigations. In particular, a refined Chalk lithostratigraphy with practical application to mapping and detailed correlation, was finally accepted by a joint stratigraphic committee of the Geological Society and the British Geological Survey in September 1999 (Mortimore 1986;Bristow et al 1997;Rawson et al 2001). This meant that a consistent set of lithological units and terms could be used for both coastlines (e.g.…”

In 1998 a European funded research programme ROCC (Risk of Cliff Collapse) was initiated by a team from France and the UK because of the growing hazard to local communities from chalk cliff retreat. Could the where, when and how of cliff collapses be answered and could the rate and scale of cliff retreat be modelled more accurately? Such answers are vital to the planners and local authorities responsible for the safety and access to cliffs and beaches. The primary research area is the eastern English Channel, where in northeast France there is 120km of Chalk coast, and in southeast England 40km in Sussex and a similar length in Kent. The research programme brought together geologists and engineers from BRGM, the University of Le Havre and the University of Brighton in partnership with the regional governments of the Somme, Seine Maritime, southeast England and their constituent local authorities. This book, representing several years of previous and concurrent research on the engineering geology of chalk and coastal processes, is the outcome of that research programme and allied work.It was fortuitous that several other chalk investigations were coming to completion prior to ROCC starting. These formed a foundation on which to build the investigations.
