  • Elevation contour lines within the Wye catchment at 10 and 20 metre intervals. The contour lines have been digitised from a scanned topographic map.

  • Digital river network of the natural and artificial streams and rivers within the Plynlimon catchments.

  • NERC grant NE/R013535/1. Here we present the dataset collected during a brine-CO2 flow-through test using a synthetic sandstone with oblique fractures, performed under realistic reservoir conditions stress. We monitored geophysical, mechanical and transport properties, for drainage and imbibition conditions, representative of the injection and post-injection stages of the CO2 storage process. We collected ultrasonic P- and S-wave velocities and their respective attenuation factors, axial and radial strains, electrical resistivity, pore pressure, temperature and brine and CO2 partial flows (from which relative permeability was later calculated).

  • EPSRC grant EP/L012227/1: Development of Unified Experimental and Theoretical Approach to Predict Reactive Transport in Subsurface Porous Media. The effect of pore-scale heterogeneity on non-Darcy flow behaviour is investigated by means of direct flow simulations on 3-D images of Estaillades carbonate. The critical Reynolds number indicating the cessation of the creeping Darcy flow regime in Estaillades carbonate is two orders of magnitude smaller than in Bentheimer sandstone, and is three orders of magnitude smaller than in the beadpack. It is inferred from the examination of flow field features that the emergence of steady eddies in pore space of Estaillades at elevated fluid velocities accounts for the early transition away from the Darcy flow regime.

  • The Mineral Reconnaissance Programme (MRP), funded by the DTI (Department of Trade and Industry) carried out baseline mineral exploration in Great Britain between 1972 and 1997. Its main aim was to stimulate private-sector exploration and the development of indigenous mineral resources. It has been subsumed into the new BGS Minerals Programme, also funded by the DTI. The Programme provides information and advice to industry, enables technology transfer and promotes wealth creation through the effective sustainable development of Britain's mineral resources. The database contains information from the MRP together with some from earlier programmes and the new Minerals Programme. Information from the early 1970s was largely concerned with the search for uranium and base-metals, while since the 1980s gold and platinum-group elements (PGEs) have dominated. A range of pathfinder elements have also been determined. Data is held on the geochemistry of drainage stream sediments, panned concentrates, soil, deep overburden, rock and drillcore samples. All geochemical results are used to populate corporate Geochemistry Database.

  • The dataset is based on a 1 hectare(ha) vector grid which covers the whole of Scotland. It has been populated with a series of environmental and cultural assets, reflecting the presence or absence of an asset in an individual cell. The dataset has been designed to enable a single asset to be displayed in a generalised fomat; total numbers of assets within a given cell; or the opportunity to create in unique combination of the assets based on the generalised 1 ha data. The data is also available at 1km.

  • The database contains a range of geochemical data for metamorphosed limestones from the Dalradian of Scotland and Northern Ireland. The data include a) whole-rock geochemical analyses by XRF (X-Ray Fluorescence) for major oxides and a range of trace elements for several hundred samples, b) a number of whole-carbonate O (oxygen) and C (carbon) stable isotope and Sr (strontium) data, c) electron microprobe mineral data on carbonates and calc-silicate minerals and d) ion-probe O stable isotope and mineral trace element data for calcites in a small number of samples. The samples from which the data have been derived were collected from a wide range of outcrops within the Scottish and Irish Dalradian, mainly concentrated in the North East Grampian Highlands of Scotland. The data have been collected mainly to support the mapping and scientific work being undertaken in the Grampian Highlands by BGS since the early 1980s. The database includes some data from the literature. All samples are located by British National Grid coordinates to the nearest 10m or better. The isotope data were acquired as part of a PhD study by C W Thomas in the late 1990s. The database is not currently being added to, but is still being used in various studies. The combined data provide wide-ranging insights into marine chemistry contemporary with deposition of the limestones and the way in which this chemistry changed with time during the Neoproterozoic, and they elucidate subsequent effects of diagenesis and metamorphism and the outcrop and grain-scale. The data set is largely complete with regard to geochemical data, but still requires some editing to bring all fields up to date, particularly with regard to lithostratigraphical assignation. The data are currently held in MS Access tables and can conveniently be displayed via GIS or abstracted in tabular form and used in spreadsheets, statistical analysis and graphing software.

  • The dataset comprises plans of various types relating to mining activity, including abandonment plans, gathered since the 1800s. Most were collected as part of the BGS mapping programme and the type and amount of data available will vary considerably. The coverage for Northern England and Scotland is more comprehensive than for the rest of the country. The plans include working copies, compilations and interpretations which may be copyright or confidential. The general nature of some of the plans means that they may not be applicable to a specific site. Current holdings over 60,000.

  • Records of all onshore (or near shore) boreholes, trial pits, shafts and wells held in the BGS archives in either paper, microfilm or digital format. The records range from simple single page lithological logs through to hydrocarbon completion reports. Spatial coverage will vary considerably depending on drilling activity, collecting activity and donations. The majority of new data is from site investigation reports with concentrations in urban areas and along transport routes. Current collection over 1million records covering the whole of Great Britain with 50,000 new records added per annum. Some records date back to 1600 but the majority date from 1900 onwards. Copies of records are available in hard copy or digital formats subject to confidentiality.

  • The Lexicon of Named Rock Units provides definitions of lithostratigraphic, lithodemic, and litho-morpho-genetic geological units of the United Kingdom and its associated continental shelf. The Lexicon focuses mainly on units of Member, Formation, Group and higher rank (and equivalents) but it also includes information on some units of lesser rank, notably economically important coal seams and laterally extensive marine bands. It includes superficial and bedrock units. It includes synonyms and other names not currently recognised by the BGS or regarded as obsolete. Full Lexicon entries include geological unit name, a persistent unique identifier, map code, currency, rank, parent unit and rank, age, lithology, definitions of boundaries, thickness, previous and alternative names, geographical extent, type localities, and bibliographical references.
