South-west Essex-M25 corridor: applied geology for planning and development
This study was commissioned by the Department of the
Environment and Lnded jointly by the Department and the
British Geological Survey (BGS). Its principal aim was to
produce a synthesis of geological information relevant to the planning of land use and development in south-west Essex
and that part of the London Borough of Havering adjacent
to the M25 London Orbital Road. This report was written
specifically for those involved in planning and development.
Geological terms have been kept to a minimum, but for
those that are necessary a glossary is appended. Much of the
information is provided by a series of thematic maps, each
one highlighting a specific aspect of the geology. For those
requiring a greater depth of geological background, additional sources of information relevant to the area are indicated
A new stratigraphy for the glacial deposits around Lowestoft, Great Yarmouth, North Walsham and Cromer, East Anglia, UK
A new stratigraphical model for the glacial deposits around Lowestoft, Great Yarmouth, North Walsham and Cromer (east of Weybourne and Edgefield) is presented, based on a
combined research programme by the British Geological Survey and the Department of Geography, Royal Holloway University of London. This stratigraphical model is founded
upon evidence derived from sedimentological descriptions, geological mapping and analytical lithological techniques including clast lithological analysis, derived pre-
Quaternary palynomorphs and heavy mineralogy. The previously accepted ‘North Sea Drift’ / ‘Lowestoft Formation’ scheme is abandoned in favour of four formations that relate to assemblages of till units and associated outwash lithofacies, the mapping of major discontinuities, and morpho- and tectono-stratigraphical associations. The new scheme consists of the Happisburgh, redefined Lowestoft, Sheringham Cliffs and Briton’s Lane formations

Revised Pre-Devensian glacial stratigraphy in Norfolk, England, based on mapping and till provenance
Mapping combined with till provenance studies have resulted in a re-appraisal of the pre-Devensian glacial stratigraphy of Norfolk, England. The traditional model invoked two formations, a North Sea Drift Formation (NSDF) overlain by a Lowestoft Formation, formed by co-existing icesheets originating in Scandinavia and Northern Britain respectively. The NSDF included three diamictons, the First, Second and Third Cromer tills.
The Briton’s Lane Sands and Gravels were considered to overlie the Lowestoft Formation. However, our work has shown this stratigraphy to be untenable, and we propose a model of several glaciations instead of co-existing ice-sheets. In our revised stratigraphy, the oldest formation, the Happisburgh Formation (including the Happisburgh or First Cromer Till) includes massive, sandy tills derived from northern Britain. The overlying Lowestoft Formation, including the Second Cromer (Walcott) Till is confirmed as derived from the west, introducing much Jurassic material as well as Chalk. The Sheringham Cliffs Formation includes both brown sandy tills (the Third Cromer Till) and ‘marly drift’, in a variety of tectonic relationships, and derived from the north and NNW. Finally the Briton’s Lane Formation is the only formation to include Scandinavian erratics. Dating of the four formations is at varying levels of confidence, with the Lowestoft Formation most confidently confirmed as MIS 12. The Happisburgh Formation is believed to represent an earlier glaciation, and MIS 16 is proposed. The Sheringham Cliffs Formation is tentatively believed to date from MIS 10, and the Briton’s Lane Formation is assigned to MIS 6

Norfolk mineral resources : mineral resource information in support of national, regional and local planning
Mineral resource information in support of national, regional and local planning : Norfolk
This report is one of a series prepared by the British Geological Survey for various
administrative areas in England for the Office of the Deputy Prime Minister’s research project
Mineral Resource Information in Support of National, Regional and Local Planning.
The accompanying map relates to the county of Norfolk and delineates the mineral resources of
current, or potential, economic interest in the area and the sites where minerals are or have been
worked. It also relates these to national planning designations, which may represent constraints
on the extraction of minerals.
Three major elements of information are presented:
• the geological distribution and importance of mineral resources;
• the extent of mineral planning permissions and the location of current mineral workings, and
• the extent of selected, nationally-designated planning constraints.
This wide range of information, much of which is scattered and not always available in a
consistent and convenient form, is presented on a digitally-generated summary map on the scale
of 1:100 000. This scale is convenient for the overall display of the data and allows for a legible
topographic base on which to depict the information. However, all the data are held digitally at
larger scales using a Geographical Information System (GIS), which allows easy revision,
updating and customisation of the information together with its possible integration with other
datasets. The information will form part of a Summary of the Mineral Resources of the East of
England Region.
The purpose of the work is to assist all interested parties involved in the preparation and review
of development plans, both in relation to the extraction of minerals and the protection of mineral
resources from sterilisation. It provides a knowledge base, in a consistent format, on the nature
and extent of mineral resources and the environmental constraints, which may affect their
extraction. An important objective is to provide baseline data for the long term. The results may
also provide a starting point for discussions on specific planning proposals for mineral extraction
or on proposals, which may sterilise resources.
It is anticipated that the maps and report will also provide valuable background data for a much
wider audience, including the different sectors of the minerals industry, other agencies and
authorities (e.g. The Planning Inspectorate Agency, the Environment Agency, the Countryside
Agency and English Nature), environmental interests and the general public.
Basic mineral resource information is essential to support mineral exploration and development
activities, for resource management and land-use planning, and to establish baseline data for
environmental impact studies and environmental guidelines. It also enables a more sustainable
pattern and standard of development to be achieved by valuing mineral resources as national
assets.
The mineral resources covered are sand and gravel, silica sand, crushed rock aggregate,
hydrocarbons, building stone, chalk and peat
