Related Material | The main resource determining if a site is affected by shale workings are the British Geological Survey's (BGS)"Oil Seam Contour" plans, which give an indication of the depth of the various seams and the approximate location of known workings and shafts /adits. These plans were produced as 6 inch to the mile overlays for the 6 inch scale geological maps. LDC reduced the plans to 1:10000 scale so that they could be overlaid on the modern OS maps.
The Archives and Records Centre holds these plans but they are not currently catalogued. Please contact the Archivist for further information. |
