Aquifer Vulnerability Maps

The Soil Survey, Land Research Centre and the British Geological Survey were commissioned by the Environment Agency to prepare 53 groundwater vulnerability maps at 1:100 000 scale. These maps identify areas in which the groundwater resources require protection from potentially polluting activities. The maps are designed to be used by planners, developers, consultants and regulatory bodies to ensure that developments conform to the Policy and Practice of the Environment Agency for the protection of Groundwater.

Buy them at the BGS Internet Shop. Folded maps are no longer available. Flat maps may be purchased from the BGS at £15 each. Sheets 16,39,40, and 43 are out of print. Currently we are unable to provide scanned copies of these maps due to Copyright restrictions. Please note that these maps are based on data from the late 1980's and early 1990's. More up-to-date digital data may now be available from the Environment Agency; for more information contact your local EA office or the National Enquiry Service (08708 506506).

Hydrogeological maps

Hydrogeological Maps have been published at various scales, covering areas ranging in size from the whole of England and Wales, Northern Ireland and to Jersey. They display information on surface water features, the three dimensional geometry of aquifers, groundwater levels, abstractions and quality including saline intrusion in varying amounts of detail. They are colour-printed maps, available either flat or as folded sheets in plastic sleeves. They cost £12.50 for one sheet or £17 for two. Buy them at the BGS Internet Shop.

There is also a 1:100 000 Fife map in Scotland (2 other maps in Scotland are under preparation). In addition we have a 1:1 000 000 National map for England & Wales, a 1:625, 000 map of Scotland and a 1:250 000 map of Northern Ireland.

Old series geological maps (1 inch)

Early geological mapping covering the OS Old Series one inch map sheet areas. Applies to England and Wales only.

UTM series 1:250 000 geological maps

These maps display Bedrock, Quaternary (Superficial deposits) geology of the offshore areas and Seabed Sediments of the UK landmass and offshore regions. The different versions are normally published as separate maps for land areas, but these may be combined on a single map for offshore areas. Maps are normally available in flat and folded format.

The UTM Series (Universal Transverse Mercator projection) maps cover an area of 1deg. latitude by 2deg. longitude.

Fuller details including the current availability of each sheet are given in the BGS Internet Shop. To search the Internet Shop for maps for a particular sheet area take note of the sheet number and type this in the Search Box on left-hand screen in the BGS Internet Shop Home Page.

Geological memoirs

This shows areas covered by explanatory sheet Memoirs. They provide a comprehensive and detailed account of all aspects of the geology of the areas covered by the 1:50 000 (and 1:63 360) map series. Some memoirs may cover more than one geological sheet area and a few cover key geological themes (eg Jurassic rocks) across a large region. Sheet Descriptions are fully colour-illustrated, shortened accounts of the geology that are available for some of the newer published geological sheets.

You may buy a memoir, by first noting the memoir name and then using the BGS Internet Shop.

A shapefile for use in your own GIS is made available for a version of this data layer.

Also, you may find out where we have digital maps for sale.

These maps show the occurrence, nature and stratigraphic age of rocks. They are available for most areas of the United Kingdom, and in a number of versions (Solid, Drift, or Solid and Drift combined). Maps are normally available in both flat and folded format. The map grids are based on the now discontinued Ordnance Survey Old Series One-inch Sheet Grids. The 1:50 000 series also includes reprinted maps that were originally published at the 1:63 360 scale.

For Scotland, maps are usually divided into eastern and western parts, for example sheets S038E and S038W, although earlier full sheets, showing different versions of the geology (see above), may still be available.

These maps show the occurrence, nature and stratigraphic age of rocks. They are available for selected areas of outstanding geological interest in the United Kingdom, and in a number of versions (Solid, or Solid and Drift combined, Bedrock or Superficial ). Maps are normally available in both flat and folded format. 1:25 000 scale maps are also available for the Channel Islands, for details please contact BGS Sales: tel 0115 936 3241; email sales@bgs.ac.uk.

Digital geological maps 10000

More information about these 1:10 000 digital geology maps and also about other scales of digital geological map data can be found at DiGMapGB. Information about licensing digital maps can be found at the BGS copyright pages.

National grid maps (1:10 000)

National grid maps (1:10 000 and 1:10 560 scale) - Since the 1960s the standard large scale map for recording geological information has been the Ordnance Survey (OS) quarter sheet, covering a 5km by 5km area. The maps are supplied in different formats depending on their age and the method of compliation or reproduction used. Only the latest and most up-to-date version is listed.

County geological maps (1:10 560 scale)

Maps produced on OS County Series sheets between approximately 1860 and 1960. The list indicates whether the map has been revised or re-surveyed and gives details of any later versions that have been produced. It is advisable to discuss your requirements before ordering or travelling to view these maps.

Local authority district boundaries (England and Wales) and region boundaries (Scotland).

Superficial deposits 1:625 000 scale

The 'Superficial deposits' shown on the GeoIndex map includes the youngest geological deposits laid down in England and Wales, Scotland and part of Northern Ireland. This map is based on the first edition Drift 1:625 000 scale Geological Map of the United Kingdom published in 1977 as two sheets, North and South, available from the BGS Internet Shop.

The Superficial deposits, mainly formed in the Quaternary period of geological time, which extends from the present back to 2 million years ago. Many of the deposits were formed during episodes of glaciation ,or deposited by rivers. They occur as discontinuous patches and larger spreads and rest on top of the older rocks (referred to in the Bedrock).

Most of these Superficial deposits are unconsolidated sediments such as gravel, sand, silt and clay. The name of each deposit or group of deposits corresponds to that shown on the published 1: 625 000 map e.g. River Terrace Deposits.

CAUTION

The source geological maps originally used to compile the published 1:625 000 maps are 1:50 000 and 1:63 360 (one inch to one mile) scale maps published before 1977. Many of these have since been up-dated and may therefore not now agree with the 1:625000 geology shown here.

Because of the generalisation and simplification used in the compilation of this map, it should not be used to determine the detailed geology of any specific sites. It is best used to provide a basic understanding of the geology of the country in general, and for showing the geology of large regions where broad trends are more important than specific details.
