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.

This report describes the City of London 3D geological model, created by Constance Martin, a BSc student at the University of Birmingham, and Ricky Terrington and Helen Burke from the British Geological Survey. The work was carried out as part of a final year geology mapping project, using existing data held by the BGS and computer modelling in place of more traditional field mapping techniques to explore the subsurface geology of the developed area of the City of London.

The City of London model covers an area covering approximately 3 km2 in Central London, where the financial district, St Paul’s Cathedral and the Tower of London are located. Eleven geological units are modelled, comprising artificial ground, superficial deposits and bedrock to a cut-off depth of 100 m below Ordnance Datum.
