The map illustrates basic components of geological environment, that is classified on the basis of similarity or homogenity of that signs, which have meaning from point of construction geology, engineering geology and geotechnics. In case of rocks and soils it is mainly lithological composition, similar index, geomechanical or geophysical characteristics, while f.e. stratigraphy (age) is put down. These similar rocks are aggregated into zones with same or similar engineering geological characteristics. The...

A list of the laboratory reports produced from testing in the engineering geology laboratory. It includes report number, title and author's name(s). The reports themselves contain data on a wide range of geotechnical and geophysical laboratory tests, from standard and index tests to complex research. Test materials are highly varied, soils and rock, from the UK or overseas.
This dataset is a characterisation of the soil and rocks and the potential bulking factor (likely excavated volume increases) at Formation (local to regional) level for Great Britain. The data is categorised into Class, characteristics of similar soils and rocks and Bulking Factor, range or ranges of % bulking. The excavation of rocks or soils is usually accompanied by a change in volume. This change in volume is referred to as ‘bulking’ and the measure of the change is the ‘bulking factor’. The bulking fa...
This dataset is a characterisation of discontinuity types found within rocks and soils in Great Britain. Discontinuities are breaks, fractures or planes of weakness in the rock mass. The dataset includes type, frequency and orientation of discontinuities within rock and soil materials at formation (local to regional) scale. The discontinuities are classified in 3 categories: stratification (bedding planes), foliation (mineral banding) and rock mass description. The dataset aims to facilitate the preliminar...
Sometimes known as the "One-Inch Collection", this is an archival collection of rock samples collected by BGS field staff during surveys within England and Wales, arranged by 1-inch (or 50 K) scale BGS geological map sheet area. It was intended as a representative suite of the lithologies present in each sheet, although this was only partially achieved. Documentation is via archive of rock sample collection sheets (see COLLECTIONSHEETS) but is poorly coordinated at present.
The collection consists of records of enquiries answered by the Land Survey from c.1939 to 1970, with a small number of earlier records. Pre c.1960 files relate mainly to economic mineral enquiries while files after that year relate increasingly to enquiries on geological site conditions. Enquiry records of former Leeds and Newcastle offices, relevant to UK(North), are held for c.1950 to 1992. Edinburgh Office enquiry files dated up to 1970 have been reviewed for retention/destruction and those of continui...
This service contains entity indexes for boreholes, grab samples and geophysical data. In this service you will find marine points and lines in Europe with geological knowledge. Each feature contains main metadata for the feature including contact details to relevant authorities.
BGS have collected environmental radioactivity data for various purposes over several decades. This is being drawn together to produce a database of baseline gamma radioactivity and radon. Data includes the relevant portions of airborne and ground gamma spectrometer surveys, mineral exploration, baseline geochemistry and environmental radiometric surveys along with lithogeochemical and borehole log data. It is predominantly a specialist subset of other existing BGS databases. Incomplete UK coverage.
