  • The Samburu - Marsabit Geological Mapping and Mineral Exploration Project was a joint Kenyan and British technical co-operation project, carried out by staff of the Mines and Geological Department, Ministry of Environment and Natural Resources, Kenya and staff from the British Geological Survey. The first phase of the project commenced in 1980, and covered the area between 36degrees and 38degrees E and from the equator to 2degrees N. The second phase, carried out between 1984 and 1986 covered the area between 36degrees and 38degrees E and from 2degrees N to the Ethiopian border. Sampling was carried out concurrently with geological mapping and was largely constrained by the requirements of that exercise. Little or no sampling was done in areas previously mapped by other bodies. Sampling was mainly confined to areas underlain by basement rocks of the Mozambique Belt and was very sparse over most of the Tertiary and Quaternary volcanic cover. Chemical analyses for the stream sediments were: Ag, Ba, Co, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, and Zn. Raw data is available from the Mines and Geological Survey Department, Ministry of Environment and Natural Resources, Nairobi, Kenya. Sampling densities varied considerably across the Phase 1 project area, but generally a stream sediment sample density of one per 4 to 8 km2 and a panned concentrate density of one per 13 to 16 km2 was achieved. In the Phase 2 area, which was mainly very arid, a few samples were collected from dry stream beds, as part of a helicopter survey of the area, to provide some idea of the geochemistry of the major lithological units. Stream sediments were collected by combining grab samples from 5 to 10 points within a 10m radius of the selected site. If necessary the samples were dried before being sieved and the fine (-80 mesh B.S.) fraction retained for analysis. Heavy mineral concentrates were obtained by taking 2 to 5kg of material from the sample site and panning at the base camp, where water was available, or at the Mines and Geological Department headquarters at Nairobi.

  • Results of two sampling campaigns conducted in Kwale County Kenya in March and June 2016 by GHS/UPC as part of the Gro for GooD project. Water samples from over 79 groundwater and 6 surface water (SW) locations were analysed for major ions, stable isotopes, selected trace constituents, electrical conductivity, nitrates, ammonia, pH, DO (Dissolved Oxygen), Eh (oxidation / reduction potential), Temperature, TOC (Total Organic Carbon) and field alkalinity. Most locations were sampled in both March (dry season) and June (wet season). Geology at each location recorded as follows: P - Pliocene Sands, Pls - Pleistocene Sands, Plc - Pleistocene corals.

  • This dataset relates to sample metadata and the results of geochemical analyses conducted on samples as part of the Mineral Reconnaissance Programme (MRP). It contains metadata including sample names, sample project areas, sample types and analytes. The MRP was a programme undertaken by BGS which ran continuously from 1973 to 1997, funded by the UK Government's Department of Trade and Industry (DTI). The datasets it produced provide baseline information on areas prospective for the occurrence of metallic minerals in particular locations across Great Britain. The programme was designed to stimulate private sector exploration and to encourage the development of Britain's indigenous mineral resources. The emphasis during the MRP varied in response to market conditions and strategic interests. Work on ‘strategic’ metals, such as platinum, palladium, chromium, cobalt and nickel, dominated the 1980s. From the late 1980s, the principal focus of the programme was gold. Numerous studies examined gold mineralisation in porphyry, epithermal, orogenic and unconformity-related settings. Towards the end of the programme, a small number of projects concerned with gemstones and industrial minerals were also completed. Various samples were taken throughout the course of the programme, including rock, soil, stream sediment, stream water and deep overburden samples. These samples underwent analysis for a variety of analytes, the results of which are held by BGS. This dataset includes the geochemical information derived from the samples and sample metadata, including the location of sampling. The sampling and analysis methodology varied by MRP project area.

  • This Web service provides a spatial index into the BGS collection of onshore borehole materials in the UK and the Isle of Man, including drillcore, bulk specimens, washed and unwashed cuttings and processed material. The boreholes have been drilled by BGS, or by commercial or public bodies. The name of the borehole, its unique reference code and number (BGS_ID) and the type of material is provided. For some boreholes, multiple types of material are available. Details of the collection are held in the Borehole Materials Database, and may be accessed via the BGS website.

  • The borehole information pack from borehole GGC01, site 10 of the UK Geoenergy Observatories (UKGEOS) Glasgow facility. This initial data release pack from BGS contains composite and digital wireline logs; drillers summary logs and prognosis; sample recovery information spreadsheets; and daily driller's borehole records. The cored, seismic monitoring borehole was drilled between 19 November and 12 December 2018 to 199m producing a core of 102 mm diameter. The borehole was wireline logged in December 2018 and a string of 5 seismometers were installed in February 2019. A range of fluid, water and core samples were taken during the drilling process.

  • The British Geological Survey onshore borehole collection database of core and sample types and depths contains records of over 15 000 onshore boreholes drilled in the UK by BGS, commercial and public bodies. Material types include continuous drillcore, core samples, individual hand specimens, bulk samples, unwashed cuttings, washed and dried cuttings, plugs, powders and bulk samples. The physical collection and database was developed as part of the British Geological Survey's responsibility to establish and maintain a national borehole collection. Details of the collection are held in the Borehole Materials Database, and may be accessed via the BGS website. The collection was initiated in 1968, and the database is updated daily by the addition of new data and by modification of existing data. Most material is stored at the facility in BGS Keyworth. Some material is held at BGS Edinburgh. The majority of borehole cores and samples are available for study and sub-sampling by bona fide academics and commercial companies. Commercial companies are charged for access; academics will need to complete an academic waiver form. Some boreholes, especially recent hydrocarbon wells, are confidential, and depths and sample details may not be given. If you require further information about these boreholes, contact kwcorestore@bgs.ac.uk for details of the owner. In a few cases, the precise map references are also confidential.
