Contains digitised mine plan contours, spot heights and worked ground outlines on key coal seams from the Midland Valley in ASCII or ArcView format. Incomplete, only some seams and some areas digitised. All contours digitised on key seams, worked ground outlines simplified, spot heights digitised where no contours exist.

Index to various collections of Aerial Photographs purchased or obtained by BGS and its precursors as part of its surveying activities. The index was set up in 2000 and mainly covers Great Britain. The level of spatial detail depends on the flight plans provided, but most are referenced at least to OS quarter sheet level.

Manuscript notebooks, section books and field record cards containing detailed information gathered by the Survey geologists (or other recognised geologists) from various sources as part of the mapping process. Examples include observations linked directly to field slips, borehole logs, sections and drawings. Note: For the basic field mapping work notebooks have now been replaced by field record cards. Covering survey areas in Great Britain from 1840's to date.

An index to the manuscript notebook collection was set up in the 1990's. The notebooks themselves contain detailed information gathered by BGS geologists (or other recognised geologists) from various sources as part of the mapping of Great Britain since the 1840s. Examples include observations linked directly to field slips, borehole logs, sections and drawings. All the notebooks held by National Geological Records Centre (NGRC) are indexed but other notebooks held in the Library may not be included. The index is to the notebooks and is not a detailed index of the information in the notebook. Detailed information from coalfield areas is held in the Happs Hall Index. For the basic field mapping work notebooks have now been replaced by field record sheets.

Primary Geological Data resulting from Open Cast Coal exploration in British coalfield areas. Maps showing the site outlines of opencast coal prospecting sites annotated with site reference number. Sites date back to the 1940s. Outlines drawn on 1:25000 scale topographic bases. The majority of the collection was deposited with the National Geological Records Centre by the Coal Authority in July 2001.

Collection of reports, notebooks interpretations, plans and other data for Great Britain received from external organisations that are not part of other collections. Covers a wide variety of topics that have been gathered over a variety of time scales.

Data resulting from deep underground coal exploration and exploitation. Collection of data, dating back to the 18th century, includes reports, interpretations and records of research in all British coalfield areas deposited by the British Coal Corporation. Data for past and current collieries and for future prospects. The majority of the collection was deposited with the National Geological Records Centre in July 2001. The collection includes borehole site plans, borehole logs , analyses and geophysical data etc. Records were selected for retention by British Coal Surveyors and BGS.

Index, set up in 1998, to the archive collection of reports, notebooks interpretations, plans and other geological or related data received from external organisations that are not part of other collections. These cover a wide variety of different types and ages of information mainly from Great Britain but some related to BGS projects overseas.

Data from the British Geological Survey's GeoIndex Minerals theme are made available for viewing here. GeoIndex is a website that allows users to search for information about BGS data collections covering the UK and other areas world wide. Access is free, the interface is easy to use, and it has been developed to enable users to check coverage of different types of data and find out some background information about the data. More detailed information can be obtained by further enquiry via the web site: www.bgs.ac.uk/geoindex.

High level index to the contents of the boxes of Primary Geological Data resulting from deep underground coal exploration and exploitation in Great Britain donated by the Coal Authority in July 2001. Data for past and current collieries and for future prospects including borehole site plans, borehole logs , analyses and geophysical data etc. This index will diminish in importance as these data are merged with existing collections.
