    Description

    The 1:63 360 / 1:50 000 scale map series are the most useful scale for most purposes. They provide almost complete coverage of onshore Great Britain. The BGS collection of 1:63 360 and 1:50 000 scale maps comprises two map series: - Geological Survey of England and Wales 1:63 360 / 1:50 000 Geological Map Series [New Series]. These maps are based on the Ordnance Survey One-inch New Series topographic basemaps and provide almost complete coverage of England and Wales, with the exception of sheet 180 (Knighton). The quarter-sheets of 1:63 360 Old Series sheets 91 to 110 coincide with sheets 1 to 73 of the New Series maps. These earlier maps often carry two sheet numbers which refer to the Old Series and the New Series. - Geological Survey of Scotland 1:63 360 / 1:50 000 Geological Map Series. These maps are based on the Ordnance Survey First, Second, Third and Fourth editions of the One-inch map of Scotland. The maps used the most recent topographic basemap available at the time. In the Western Isles, one-inch mapping was abandoned and replaced by maps at 1:100 000 scale, which are associated with this series. Sheets were traditionally issued at 1:63 360 scale, with the first 1:50 000 maps appearing in 1972. Sheets at 1:50 000 scale may be either facsimile enlargements of an existing 1:63 360 sheets, or may contain new geology and cartography. The latter bear the additional series designation '1:50 000 series'. Within the Scottish series, new mapping at 1:50 000 scale was split into east and west sheets. For example, the original one-inch sheet 32 became 1:50 000 sheets 32E and 32W. A number of irregular sheets were also introduced with the new 1:50 000 scale mapping. There are a number of irregular special sheets within both series. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. The most common map themes held by BGS are solid (later referred to as bedrock) and drift (later referred to as superficial). These maps are, for the most part, hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

    Description

    The Feature Layer made available to the Living Atlas has been adapted from the 625k Geology dataset freely available from the BGS website. The attribution and labels of the geological areas (or polygons) have been simplified to make the data more available to a wider audience. The dataset is aimed at students with an interest in Earth Sciences and amateur geologists who want to find out more. The LEX_RCS & LEX_ROCK codes have been preserved to allow users to reference the layers to to the 625k Geology Dataset.

    About BGS Geology 625k:

    BGS Geology 625k is a generalised digital geological map dataset based on BGS’s published poster maps of the UK (north and south). Bedrock-related themes were created by generalisation of 1:50 000 data to make the 2007 fifth edition bedrock geology map. Superficial geology-related themes were digitised from the 1977 first edition Quaternary map (north and south). Many BGS geology maps are now available digitally. The Digital Geological Map of Great Britain project (formerly known as DiGMapGB) has prepared 1:625 000, 1:250 000, 1:50 000 and 1:10 000-scale datasets for England, Wales, and Scotland. Work continues to upgrade these. Geological maps are often the foundation for many other earth science-related maps and are of potential use to a wide range of end users. This dataset uses the themes:

    Bedrock Geology Superficial Geology Linear features (faults)

    More information on the BGS 625k Geology Dataset can be found on the BGS website.  The 625k Geology data can also be viewed alongside other BGS datasets in the GeoIndex viewer. The currency of this data is August 2022, while there are no planned regular updates, BGS continuously reviews its data products and will release new versions of the BGS Geology 625k when available.

    Description

    Bedrock is the solid rock at or below the land surface. Over much of Ireland, the bedrock is covered by materials such as soil and gravel. The Bedrock map shows what the land surface of Ireland would be made up of if these materials were removed. As the bedrock is commonly covered, bedrock maps are an interpretation of the available data. Geologists map and record information on the composition and structure of rock outcrops (rock which can be seen on the land surface) and boreholes (a deep narrow round hole drilled in the ground). Areas are drawn on a map to show the distribution of rocks. To produce this dataset, the Geological Survey Ireland (GSI) bedrock geology 1:500,000 and 1:100,000 maps were generalised. The Northern Irish data was generalised using the Geological Survey of Northern Ireland (GSNI) 1:250,000 bedrock geology map. The UK data was generalised using the British Geological Survey (BGS) 1:650,000 bedrock geology map. This map is to the scale 1:1,250,000. When printed at that scale 1cm on the map relates to a distance of 12.5km.The map is intended to be used as a teaching resource.

    Description

    Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:625 000 scale providing a simplified interpretation of the geology. Onshore coverage is provided for all of England, Wales, Scotland, the Isle of Man and Northern Ireland. Bedrock geology describes the main mass of solid rocks forming the earth's crust. Bedrock is present everywhere, whether exposed at surface in outcrops or concealed beneath superficial deposits or water bodies. The bedrock geology of the UK is very diverse and includes three broad classes based on their mode of origin: igneous, metamorphic and sedimentary. The data includes attribution to identify each rock type (in varying levels of detail) as described in the BGS Rock Classification Scheme (volumes 1-3 ). The bedrock has formed over long periods of geological time, from the Archean eon some 7500 million years ago, to the relatively young Pliocene, 58 million years ago. The age of the rocks is identified in the data through their BGS lexicon name (published for each deposit at the time of the original survey or subsequent digital data creation). For stratified rocks i.e. arranged in sequence, this will usually be of a lithostratigraphic type. Other rock types for example intrusive igneous bodies will be of a lithodemic type. More information on the formal naming of UK rocks is available in the BGS Lexicon of Named Rock Units. Geological names are based on the lithostratigraphic or lithodemic hierarchy. The lithostratigraphic scheme arranges rock bodies into units based on rock-type and geological time of formation. Where rock-types do not fit into the lithostratigraphic scheme, for example intrusive, deformed rocks subjected to heat and pressure resulting in new or changed rock types; then their classification is based on their rock-type or lithological composition using visible features such as texture, structure, mineralogy. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are delivered free of charge under the terms of the Open Government Licence.

    Description

    For much of the Geological Survey's existence, the County Series of maps were the standard large-scale maps on which geological mapping was undertaken. These maps are based on the Ordnance Survey County (or six-inch to the mile) series of maps. These maps were cut up to be used in the field to record geological observations, and on return to the office, the geology was transferred to a complete County Series map, which after approval was known as a 'standard' (England / Wales) or 'clean copy' (Scotland). This dataset contains the 'standard' or 'clean copy' County Series maps held by BGS. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. The most common map themes held by BGS are solid (later referred to as bedrock) and drift (later referred to as superficial). These maps are hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

    Description

    A series of maps at the detailed scale of 1:25 000 have been produced for areas of outstanding geological interest in Great Britain. Some maps are accompanied by explanatory booklets. The maps were published between 1954 and 2007. About 60 maps have been published, some showing solid geology, some drift geology and some combined solid and drift. Most of the maps include geological cross sections and generalised vertical sections. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. These maps are hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

    Description

    A series of maps describing geological factors relevant to offshore seabed activities. Produced in collaboration with The Crown Estate in 2014. The Bedrock Summary Lithologies dataset is a digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200m, which groups the bedrock lithologies (rock types) into classes based on similar engineering geology characteristics. The map is derived from the 1:250,000 scale digital bedrock map of the UKCS, called DiGRock250k, which is available separately from the BGS. The map was produced in 2014 in collaboration with The Crown Estate as part of a project to assess seabed development opportunities across the UKCS. This map has been released for viewing on the Offshore GeoIndex alongside a series of other offshore geological maps from the BGS.

    This dataset contains the .tif (Tag Image File Format) scans of all the applied geology maps (otherwise known as thematic or environmental) and sections produced as part of "Geological background for planning and development" and preliminary sand and gravel projects carried out by the British Geological Survey for the Department of the Environment, Scottish Development Department and Scottish Office from 1975 to 1996. The maps and sections cover a number of themes for specific areas relating to the project area within the United Kingdom. Metadata on the maps, sections and project reports are in the associated excel spreadsheet. The geological line work and the methods used to produce the maps are those current at the time of production. Map scales are 1:10 000, 1:25 000 and 1:50 000. The maps have Ordnance Survey map bases and are bounded by the project area. The maps could be used for geological, engineering geological, environmental and resources research, as an information and reference resource and for inclusion in reports and papers. There are no access or usage constraints for BGS staff for BGS purposes. The scans are .tif files and can, therefore, be displayed using any suitable package. The original file size varies between 170 kb to 250 Mb. The dataset is stand-alone.

It integrates geological information from a variety of sources. These include recent digital maps, older 'paper only' maps, and desk compilations for sheets with no published maps.

    Description

    This layer is deprecated.The generalised BGS geology data is now available in the ArcGIS Living Atlas hereGeneralised digital geological map data based on BGS's published poster maps of the UK (North and South). Bedrock related themes created by generalisation of 1:50 000 data to make the 2007 fifth edition Bedrock Geology map.

    Superficial related themes digitised from 1977 first edition Quaternary map (North and South).

    Many BGS geology maps are now available digitally. The Digital Geological Map of Great Britain project (DiGMapGB) has prepared 1:625 000, 1:250 000, 1:50 000 and 1:10 000 scale datasets for England, Wales and Scotland. Work continues to upgrade these.

    The geological areas (or polygons) are labelled or attributed with a name (based on their lithostratographical, chronostratographical or lithodemic nomenclature) and their composition (rock type or lithology). This information is arranged in two themes: bedrock geology and superficial deposits. Faults and other linear features are available in a separate theme.

    Geology maps are the foundation for many other types of earth science related maps and are of potential use to a wide range of customers.The original dataset can be found here.

    Description

    250k Bedrock Geology A 1:250,000 map showing the main geological bedrock divisions in Northern Ireland. The data comprises the bedrock geology, which represents the outcrops (at surface) and subcrops (at near-surface, beneath superficial deposits) in Northern Ireland. For each rock unit there is a brief generalised description showing the major rock group, rock type and age under the following headings. LEX_D: The name of the selected area. This can be a group, formation or igneous intrusion e.g. dyke. LEX_RCS: Map code as it appears on the published 1:250,000 map. RCS_D: The name of the dominant types of rock (lithologies) in the different areas shown on the map e.g. granite. The names of the rock types given here are often generalisations, appropriate for the large areas of geological coverage at this scale. These areas may include a number of different geological formations whose distribution can only be portrayed on more detailed geological maps. RANK: Identifies formations and groups. Min_Time_D and Max_Tim_D: The age of the rock unit in terms of periods, relatively smaller units of geological time e.g. Carboniferous, Jurassic etc. Some of the map areas include rocks with a range of ages and these are shown as such e.g. Triassic to Cretaceous. The oldest metamorphic rocks are described as Moinian and Dalradian. The rocks range in age from those deposited relatively recently, some 2 million years ago, back to ancient and highly altered Precambrian rocks over 2500 million years old. In broad terms the youngest rocks are found in the south and east of the UK, the oldest in the north and west. 250K Superficial Geology This layer shows the superficial (drift) geology of Northern Ireland at 1:250,000 scale. 250K Bedrock Lines This layer shows bedrock features such as faults at 1:250,000 scale.

    Description

    The BGS collection of 1:10 560 / 1:10 000 National Grid Series geological maps. These maps are based on the Ordnance Survey National Grid series of maps, which are defined by the 10 km intervals of the larger 100 km square identified by a specific two-letter code. Each map is thus denoted by a unique reference, e.g. SP 29 NW. SP=100 km square; 29=10 km square; NW=5 km square. Since field mapping is generally undertaken at the scale of 1:10 000 (or equivalent), these maps are the largest-scale main series of geological maps that BGS holds. A small number of remote areas were mapped at 1:25 000 scale, the subsequent maps are also at 1:25 000 scale and are included in this series. The equivalent to the National Grid Series prior to the 1960s is the County Series (at 1:10 560 scale). In the 1960s, this series started to be replaced by 6 inches to 1 mile (1:10 560 scale) National Grid sheets based on the four quadrants (NW, NE, SW, SE) of a 10 km Ordnance Survey National Grid square. Areal coverage provided by the National Grid series of large-scale maps is limited in extent and the preceding County series of six-inch maps can still be the most up to date map available for some areas. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. The most common map themes held by BGS are solid (later referred to as bedrock) and drift (later referred to as superficial). These maps are, for the most part, hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

Description

The 1:63 360 / 1:50 000 scale map series are the most useful scale for most purposes. They provide almost complete coverage of onshore Great Britain. The BGS collection of 1:63 360 and 1:50 000 scale maps comprises two map series: - Geological Survey of England and Wales 1:63 360 / 1:50 000 Geological Map Series [New Series]. These maps are based on the Ordnance Survey One-inch New Series topographic basemaps and provide almost complete coverage of England and Wales, with the exception of sheet 180 (Knighton). The quarter-sheets of 1:63 360 Old Series sheets 91 to 110 coincide with sheets 1 to 73 of the New Series maps. These earlier maps often carry two sheet numbers which refer to the Old Series and the New Series. - Geological Survey of Scotland 1:63 360 / 1:50 000 Geological Map Series. These maps are based on the Ordnance Survey First, Second, Third and Fourth editions of the One-inch map of Scotland. The maps used the most recent topographic basemap available at the time. In the Western Isles, one-inch mapping was abandoned and replaced by maps at 1:100 000 scale, which are associated with this series. Sheets were traditionally issued at 1:63 360 scale, with the first 1:50 000 maps appearing in 1972. Sheets at 1:50 000 scale may be either facsimile enlargements of an existing 1:63 360 sheets, or may contain new geology and cartography. The latter bear the additional series designation '1:50 000 series'. Within the Scottish series, new mapping at 1:50 000 scale was split into east and west sheets. For example, the original one-inch sheet 32 became 1:50 000 sheets 32E and 32W. A number of irregular sheets were also introduced with the new 1:50 000 scale mapping. There are a number of irregular special sheets within both series. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. The most common map themes held by BGS are solid (later referred to as bedrock) and drift (later referred to as superficial). These maps are, for the most part, hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.
