Burke, H, Martin, C, and Terrington, R. 2018. Metadata report for the City of London 3D geological model. British Geological Survey Internal Report, OR/18/030.

The City of London geological model covers an area of approximately 3 km2 in central London (Figure 1) and comprises eleven artificial, superficial and bedrock geology units. The six modelled superficial deposits comprise alluvium and terrace gravels associated with the River Thames, which overlie three modelled Palaeogene bedrock units and a basal unit of Cretaceous Chalk. The model is suitable for use at scales between 1:10 000 and 1:50 000 to a depth of 100 m below Ordnance Datum (OD).
