  • Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:25 000 scale. Onshore coverage is partial and BGS has no intention to create a national coverage at this scale. Areas covered are essentially special areas of 'classic' geology and include Llandovery (central Wales), Coniston (Lake District) and Cuillan Hills (Isle of Skye). Superficial deposits are the youngest geological deposits formed during the most recent period of geological time, the Quaternary, which extends back about 2.58 million years from the present. They lie on top of older deposits or rocks referred to as bedrock. Superficial deposits were laid down by various natural processes such as action by ice, water, wind and weathering. As such, the deposits are denoted by their BGS lexicon name, which classifies them on the basis of mode of origin (lithogenesis) with names such as, 'glacial deposits', 'river terrace deposits' or 'blown sand'; or on the basis of their composition such as 'peat'. Most of these superficial deposits are unconsolidated sediments such as gravel, sand, silt and clay. The digital data includes attribution to identify each deposit type (in varying levels of detail) as described in the BGS Rock Classification Scheme (volume 4). 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 available under BGS data licence.

  • Data identifying linear features (shown as polylines) representing geological faults at the ground or bedrock surface (beneath superficial deposits). The scale of the data is 1:625 000 scale providing a simplified interpretation of the linear features and may be used as a guide at a regional or national level, but should not be relied on for local geology. Onshore coverage is provided for all of England, Wales, Scotland, the Isle of Man and Northern Ireland. Geological faults occur where a body of bedrock has been fractured and displaced by large scale processes affecting the earth's crust (tectonic forces). The digital data are attributed by fault type; two categories of fault are described in the data: fault at rockhead (representing normal dip-slip and strike-slip faults) and thrust fault (representing faults caused by compressive forces). The data has been generalised and shows only the location of major faults. 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.

  • The data consists of a spreadsheet containing gas column height, CO2 content and estimated retained buoyancy pressures for Southern North Sea gas fields, based on published information. The data were obtained from published field records and papers on behalf of the 'Fault seal controls on CO2 storage capacity in aquifers' project funded by the UKCCS Research Centre, grant number UKCCSRC-C1-14.

  • This data set is an inventory of aerial photographs held at BGS, Murchison House office and consists of a MS Excel spreadsheet containing 11 worksheets. Each worksheet contains information pertaining to the different sub-collections within the collection (9 worksheets of aerial photographs, one for aerial photograph scans, one for satellite imagery). Quality and coverage of metadata varies from worksheet to worksheet, depending on the size of the sub-collection, its pre-existing organisation, and the way in which the sub-collection was brought together (if it was not a complete entity when the inventory was started). Areal extent ranges from Shetland in the N (1200000) to the southern Lake District in the S (480000) and from Barra in the W (65000) to Stockton-on-Tees in the E (450000). By late 2001 all photos (except those being worked on by cuurently by staff) were catalogued in the inventory spreadsheet. By late 2003, the inventory spreadsheet had been updated with newly purchased and newly discovered photos as well as modified to include details of digital holdings and satellite imagery.

  • 1:50,000 maps showing the main geological bedrock divisions in Northern Ireland. The bedrock shown on each map 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. VERSION: Version of the data. RELEASED: Date of release/update of the data. CAUTION 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. Persons interested in the detailed geology of particular sites should consult the latest large-scale maps or the Geological Survey of Northern Ireland at:- Geological Survey of Northern Ireland Colby House Stranmillis Court Belfast BT9 5BF

  • Revised full proposal for scientific drilling (852-CPP2) 'GlaciStore: Understanding Pleistocene glaciation and basin processes and their impact on fluid migration pathways (North Sea)', submitted to Integrated Ocean Discovery Programme (IODP) April 2016. The proponent 'GlaciStore' consortium comprises research and industry organisations from the UK, Norway, USA and Canada. The full proposal describes the relationship of the proposed research with the IODP science plan, sets the regional background and describes and illustrates three scientific objectives. The objectives are to: establish a high-resolution depositional and chronological framework defining multiple cycles of glacial advance and retreat over the last 2.6 Ma by investigating the strata preserved in the centre of the NSB by scientific drilling, sampling and detailed analysis; investigate how the temporal variations in depositional environment and geochemistry of the different stratigraphic units have affected the pore fluids (dissolved gases, salts and isotopes) and the microbial community; determine the measurable impact on geomechanical properties of strata (porosity, rock stiffness, in-situ stresses, pore pressure, fractures) caused by cycles of glacial loading and unloading. The drilling and sampling strategy, standard drilling and logging operations and the specialist measurements expected to be taken are described. Related initiatives and wider context of the proposed research also the initial and planned strategy for support from industry and government are outlined. The lead submitter, on behalf to the GlaciStore consortium is Heather Stewart, British Geological Survey (BGS).The 32 proponents from the UK and Norway (BGS, Institute for Energy Technology, Lundin Norway AS, Memorial University of Newfoundland, SINTEF Energy Research, Statoil ASA, University of Bergen, University of Edinburgh University of Oslo, University of Texas at Austin and University of Ottowa) and their expertise are listed and detailed. Site forms for each of the 13 proposed drilling sites are included.The full proposal is a pdf format file. This is restricted to the proponents for publication and to progress to a revised full proposal accepted for drilling by IODP. UKCCSRC Grant UKCCSRC-C1-30.

  • The data consists of a poster presented at 'The Geology of Geomechanics' conference, held at Burlington House, London by the Geological Society on 28-29 October, 2015. The poster describes an overview of work carried-out on behalf of the 'Fault seal controls on CO2 storage capacity in aquifers' project funded by the UKCCS Research Centre, grant number UKCCSRC-C1-14. The CO2-rich natural gas accumulations of the Fizzy and Oak fields are examined for their fault-seal potential, in particular accounting for the impact of IFT and contact angle on capillary threshold pressures. Results of an in situ stress study for the Inner Moray Firth is also presented, with results being applied to a geomechanical stability analysis of faults affecting the Captain Sandstone saline aquifer formation.

  • This dataset is an additional sample list, as an Excel spreadsheet, providing details of the major sample suites collected by Delia Cangelosi during SoS RARE and not added to the master spreadsheet ( It includes location details and descriptions for rock samples collected in China and Namibia. Most material is still held by the institutions that did the work, as recorded in the sample list.
