Geological map and key showing the range and distribution of different rock types in the Eastern England region, in relation to major towns and cities. The extent of the Eastern England region is defined on the inset map of the United Kingdom. P902254.

This account provides a general description of the geology of Eastern England, a region that extends along the coast from the Tees to the Wash, passing inland to encompass large parts of Lincolnshire, Humberside, eastern North Yorkshire, southern Cleveland and the eastern fringe of Nottinghamshire. Figure P902254 provides a geological sketch map of this region showing the rock types occurring in relation to the major towns and cities. This account outlines the geology of the region to a depth of at least a kilometre and summarises the current and historical use of the geological resources in the area.

The region’s diverse landscape comprises low-lying plains, steep ridges and upland areas. This varied topography relates to the underlying geology and the major geological events that have sculpted the region. Close to the ground surface the region’s geology is relatively well known based on information from quarries, natural outcrops and the interpretation of features in the landscape. At depth, the varied uses of the subsurface have generated information including borehole records and mine plans that help to understand the geology. Over 640 boreholes in the region reach a depth of 1000 m or more and geophysical seismic surveys have also been undertaken which provide information on the rocks by sending sound waves through the ground. These surveys provide an infill between the boreholes and help the understanding of the deeper geological structure. However, this information is mostly clustered in areas where the coal and gas reserves are found. Consequently, our understanding of the region’s geology is better in some areas, and this understanding is generally poorer at depth.
