Summary report on the geology of the proposed HS2 Route (3) in the Chesham and Amersham Constituency
This brief open-file report summarises the information available from the British Geological Survey (BGS), a component body of the Natural Environment Research Council (NERC), on the geology, hydrogeology and potential geological hazards of the proposed HS2 Route 3 within the Chesham and Amersham Constituency, and surrounding areas.
The report summarises the geology and hydrogeology of the district and highlights geological and hydrogeological considerations that may need further investigation along the route.
Further review and analysis of existing data and possible field investigation would be required to confirm details of the local geology.
The report was requested by Mrs Cheryl Gillan MP following a meeting with Dr Martin Smith, Head of Geology & Landscapes programme, on Monday 16th May 2011 at the offices of the Secretary of State for Wales in Whitehall
Minerals safeguarding areas for Shropshire and Telford & Wrekin
Minerals Policy Statement 1: Planning and Minerals (DCLG, November 2006) requires all
Mineral Planning Authorities to define Mineral Safeguarding Areas (MSAâs). This report
describes work carried out by the British Geological Survey on behalf of Shropshire County
Council and Telford & Wrekin Council to delineate Mineral Safeguarding Areas in Shropshire,
Telford & Wrekin. The report uses the methodology outlined in âA guide to mineral
safeguarding in Englandâ (McEvoy et al., 2007).
Maps showing the extent of individual mineral resources in Shropshire and Telford & Wrekin
have been prepared by the BGS. Minerals Safeguarding Areas have then been defined for each
mineral resource. This data has been provided in digital form for use with a geographical
information system
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 âNorth Sea Driftâ / âLowestoft Formationâ 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 Britonâs Lane formations
The sand and gravel resources of the country around Whitchurch and Malpas, Clwyd, Cheshire and Shropshire : description of 1:25,000 sheet SJ 44, 54
The geological maps of the Institute of Geological
Sciences, pre-existing borehole information and 99 boreholes
drilled for the Industrial Minerals Assessment Unit
form the basis of the assessment of the sand and gravel
resources of the country around Whitchurch and Malpas.
The glacial sediments of the district proved to be
more complex than is shown on the published geological
map. Glacial Sand and Gravel, present over much of the
area in the south and east, shows rapid lateral and
vertical variation in composition although sand-grade
deposits predominate. Recorded thicknesses of overburden
and waste also have a wide range.
All the deposits in the district that might be potentially
workable for sand and gravel have been investigated
and a simple statistical method has been used to
estimate the volume. The reliability of the volume
estimates is given at the symmetrical 95 per cent
probability level.
The 1:25 000 map is divided into 7 resource blocks,
containing between 2.9 and 37.2 km2 of sand and gravel.
For each block the geology of the deposits is described,
and the mineral-bearing area, the mean thicknesses of
overburden and mineral and the mean gradings are
stated. Detailed borehole data are also given. The geology,
the position of the boreholes and the outlines of the
resource blocks are shown on the accompanying map
Aggregate supply and demand for sustainable communities : a practical approach to problem-solving [executive summary]
Adequate supply of aggregate resources is vital for developing and
sustaining our modern society. However, these resources are finite
and can only be extracted from where they occur.
The Milton Keynes and South Midlands (MKSM) Growth Zone
was first identified by the Regional Planning Guidance for the
South East (RPG9, 2001). The Sustainable Communities Plan,
published by the former ODPM in 2003, to help address the acute
housing shortage in England a sustainable pattern of development,
identified potential for up to 370 000 new homes within the
Growth Zone by 2031. The Milton Keynes & South Midlands Sub-
Regional Strategy (2005) provides a detailed analysis of areas with
potential for development within the Growth Zone and considers
factors including employment, transport links and utilities.
This report presents an analysis of aggregate resource
availability in and around the growth zone. It also
considers past and present aggregate supply and demand,
environmental factors, and transport and planning issues. It
aims to establish mechanisms for supplying the resources
required to develop sustainable communities in designated
growth zones.
The Project Area encompasses the MKSM Growth Zone and
surrounding areas with potential sand and gravel resource. This executive summary provides a digest of a much more detailed
technical report â âAggregate supply and demand for sustainable
communities: a practical approach to problem solvingâ (Harrison
et al., 2007). It is intended for use principally by those involved in
planning and economic development
Mineral resource information for development plans : phase one Northamptonshire resources and constraints
This report is one of a series prepared by the British Geological
Survey for various administrative areas in England and Wales for
Phase One of the Department of the Environment, Transport and the
Regions Research Project Mineral Resource Information for
Development Plans.
The report and accompanying map relate to the area of the Mineral
Planning Authority of Northamptonshire. The report and map
delineate and describe the mineral resources of current, or potential,
economic interest in the area and relate these to national planning
designations which may represent constraints on the extraction of
minerals. Three major elements of information are presented and
described:
⢠the geological distribution and importance of mineral resources
⢠the extent of mineral planning permissions and the location of
current mineral workings
⢠the extent of selected planning constraints (national statutory
designations)
This wide range of information, much of which is scattered and not
always available in a consistent and convenient form, is presented as
a digitally-generated summary map. The map is produced at 1:100
000 scale, which is convenient for overall display and allows for a
legible topographic base on which to depict the information. In
addition, as the data are held digitally using a Geographical
Information System (GIS), easy revision, updating and
customisation are possible, including presentation of subsets of the
data at larger scales.
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 sustainable pattern and standard of development to be
achieved by valuing mineral resources as national assets.
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, by providing a knowledge base on the nature and
extent of mineral resources and the environmental constraints which
may affect their extraction. However, it is anticipated that the map
and report will also provide valuable data for a much wider
audience, including the minerals industry, the Planning Inspectorate,
the Environment Agency, the Countryside Agency, other agencies
and government bodies, environmental interests and the general
public. The mineral resource information has been produced by the
collation and interpretation of data principally held by the British
Geological Survey. The methodology for the collection and display
of the data is described and a range of sources of information and
further contacts is presented. The mineral resources described are
sand and gravel, limestone, building stone, ironstone, refractory
clay, hydrocarbons and secondary aggregates
