Profile soil analyses are available from a number of BGS programmes, notably the Mineral Reconnaissance Programme (MRP) and the Geochemical Baseline Survey of the Environment (G-BASE) programme. Sampling depth and range of analytes determined is very variable for the MRP. G-BASE samples are consistently from 35 - 50 cm though since 2003 it has become routine practice in the G-BASE project to collect a top soil and deeper profile sample from the same site but only analyses the top soil and store the profile soil. This also applies in urban areas. The G-BASE profile soils were generally sieved to 150 microns before analysis and determined by XRFS for some or all of: Mg, P, K, Ca, Ti, Mn, Fe, V, Cr, Co, Ba, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Y, Zr, Nb, Mo, Pb, Bi, Th, U, Ag, Cd, Sn, Sb, Cs, La, Ce, Ge, Sc, Se, Br, Hf, Ta, W, Tl, Te and I. MRP samples can include profile samples from greater than 1 meter collected using a power auger and also include till samples. The G-BASE samples are collected at a density of 1 sample per two square kilometres in rural areas and 4 samples every kilometre square in urban areas. MRP sampling was more site specific generally collecting soil samples along lines at spacing intervals generally 25 - 250 m.

This layer of the map based index (GeoIndex) provides an index to a sub set of the BGS Report Series. The reports themselves describe the local geology and are designed to be read in conjunction with their complementary map or maps. Additional information such as hydrogeology, engineering geology, geological hazards, economic minerals and made and worked ground or other specialist topics of local interest may be included.

The surveys shown on the map based index (GeoIndex) include; Analogue airborne magnetic surveys of Great Britain for the Geological Survey (GSGB), commercial analogue survey of North Sea by Aeroservices Inc, subsequently digitised by BGS, commercial digital (+ one analogue) surveys off NW/N/NE of Britain by Huntings Geology and Geophysics, purchased outright by BGS and Local surveys, digital and analogue aeromagnetic (+ other methods) surveys for BGS and commercial companies.

This layer of the map based index (GeoIndex) shows the locations where stream sediment samples are collected under the G-BASE (Geochemical Baseline Survey of the Environment) programme at an average density of approximately one site per 1.5 km square. Analytical data for the minus 150 micron fraction of stream sediment samples are available for some or all of the following elements by a variety of analytical methods (now predominantly XRFS): Mg, P, K, Ca, Ti, Mn, Fe, V, Cr, Co, Ba, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Y, Zr, Nb, Mo, Pb, Bi, Th, U, Ag, Cd, Sn, Sb, Cs, La, Ce, Ge, Sc, Se, Br, Hf, Ta, W, Tl, Te and I. Stream sediment samples were also collected by the now defunct MRP programme and analytical data for the minus 150 micron fraction of samples is available for a variety of elements including Ag, As, Au, Ba, Bi, Ca, Ce, Cu, Fe, Mn, Mo, Ni, Pb, Sb, Sn, Sr, Ti, U, V, W, Zn and Zr. Some of the MRP samples may have undergone several stages of analysis, some for inclusion in the G-BASE project. The samples may have been assigned a different sample number but will plot at the same site. Data is available for most Great Britain, apart from some parts of Southern England which have yet to be surveyed.

This layer of the Map based index (GeoIndex) shows where water wells exist with data available on transmissivity, storativity and discharge/drawdown. These parameters indicate the physical characteristics of the aquifer which can relate to factors such as possible storage capacities or rate of movement of water through the rock.

The index shows the availability of county series geological maps, 1:10560 scale. The maps themselves were 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.

This layer of the map based index (GeoIndex) shows the locations of the Mineral Reconnaissance Programme Reports within Great Britain. The Mineral Reconnaissance Programme (MRP), funded by the Department for Trade and Industry (DTI), carried out mineral exploration reconnaissance in Great Britain between 1972 and 1997. The programme provided geological, geochemical, geophysical, mineralogical and metallogenic information on prospective areas in Britain. Work was carried out at various scales, from regional reconnaissance surveys or appraisal, to the drilling of a geochemical or geophysical anomaly. Projects were multidisciplinary, and used a combination of tried and tested methods, together with innovative techniques arising from research and development programmes. By the end of the Programme in 1997, 146 MRP reports had been issued covering localities across the UK. The programme was very successful in that more than half the projects reported attracted significant commercial follow-up resulting in the discovery of many new prospects. The reports themselves are being made available, for free, to downlaod over the next twelve months.

This layer of the map based index (GeoIndex) shows unadjusted ship gravity, magnetic and bathymetry data acquired by BGS as part of its Offshore Reconnaisance Mapping Programme. This programme commenced in 1967, and was funded mainly by the Department of Energy. Unadjusted ship gravity and bathymetry data from various commercial and academic surveys between 1965 and 1994. Confidential M.O.D Hydrographic Office integrated ship gravity and magnetics surveys of NW Europe marine areas for which BGS acts as agent. Network adjusted gravity and magnetic compilations of data from BGS and non-BGS sources.

This layer of the GeoIndex shows the location of available 1:10000 scale digital geological maps within Great Britain. The Digital Geological Map of Great Britain project (DiGMapGB) has prepared 1:625 000, 1:250 000 and 1:50 000 scale datasets for England, Wales and Scotland. The datasets themselves are available as vector data in a variety of formats in which they are structured into themes primarily for use in geographical information systems (GIS) where they can be integrated with other types of spatial data for analysis and problem solving in many earth-science-related issues. The DiGMapGB-10 dataset is as yet incomplete, current work is concentrated on extending the geographical cover, especially to cover high priority urban areas.

This layer of the Map based index (GeoIndex) shows the location of registered samples of drillcore and washed cuttings from onshore boreholes drilled in UK by BGS, commercial and public bodies, representing almost 10,000 boreholes. There is also a drillcore collection taken from onshore boreholes drilled in England and Wales by the BGS and commercial and public bodies.
