[This metadata record has been superseded, see http://data.bgs.ac.uk/id/dataHolding/13606289] Scanned images of 78 maps covering 13 National Grid 1:10,560 map areas in the area of the Lothian oil-shale field. Each map shows the extent of a single oil shale seam. They were published between 1977 and 1982 by the Institute of Geological Sciences in Edinburgh. The original maps were scanned in 2014.

A collection of seventy-eight maps covering thirteen National Grid 1:10 560 map sheets in the area of the Lothian oil shale field published between 1977 and 1982. Each map shows the extent of a single oil shale seam. An oil shale seam refers to a layer or deposit of sedimentary rock rich in organic material known as kerogen, which has the potential to yield hydrocarbons such as oil and gas through a process called pyrolysis. Oil shale is different from conventional oil and gas reservoirs in that the hydrocarbons are not present in a liquid or gaseous form but are trapped within the solid structure of the shale rock. The maps were published by the Institute of the Geological Sciences in Edinburgh (previous name for the British Geological Survey). This entry relates to hardcopy maps stored in the National Geological Data Centre (NGDC) and digital files produced by scanning them, as well as any derivative files. These maps are hard-copy paper records stored in the National Geoscience Data Centre (NGDC).

Mining hazard (not including coal) summarises the location, extent and indicates the level of hazard associated with former and present underground mine workings. The dataset covers Great Britain and is published at 1: 50 000 scale. The content is derived from a range of data sources including, but not limited to the bedrock geology, extensive literature reviews of both published and unpublished documents, abandonment and mine plans, combined with a wealth of expert knowledge and experience. The release of version 8 builds on the content of previously published versions. The coverage has been expanded with the inclusion of newly identified areas and drawing on data from the BGS published Britpits (BGS database of British Pits -includes both surface and underground mineral workings) and other resources. For the first time, zones of influence have been integrated (for evaporites, oil shales and building stones) to indicate the areas surrounding mining sites which might be impacted. The data have been compiled and presented in an easy to use format to provide a national overview of the country's mining legacy. Given the long and complex mining history of Great Britain, this dataset represents the best information available at the present time (September 2020). Work continues to develop this product, which will result in the release of ad hoc updates in the future.
