Metadata report for the Cardiff superficial deposits 3D geological model

The objective of this work was to assemble a geological framework model and calculated surfaces for the superficial deposits for the city of Cardiff. The model has a number of purposes: - To investigate the superficial deposits within the city of Cardiff and surrounding area. - To provide a communication tool to present the geological understanding of the superficial deposits of the area. - To provide information on the subsurface distribution and thickness of the main superficial deposits (principally Till, Glaciofluvial Deposits, Alluvium and Tidal Flat Deposits) of Cardiff to inform a project which is presently investigating the potential for shallow geothermal energy in the city of Cardiff (BGS, 2018). A series of 340 cross-sections have been constructed to form a fence diagram using Geological Surveying and Investigation in 3D (GSI3D) software. The sections cover much of the most densely populated areas of the city and include an area of boreholes, presently being investigated to evaluate the potential for ground source heat in part of the city. Geologists’ knowledge has been applied to incorporate subsurface data (1330 boreholes from a total of 3090 boreholes within the project area) and surface geological mapping to provide an interpretation of the geological succession, utilising BGS 1:50 000 and 1:10 000 scale geological maps.
