{{OR/18/003}}
Whilst every effort has been made to match the modelled units to the borehole logs and geological map data, there are occasions when the two datasets disagree. In these instances, precedence is given to the boreholes and adjustments were made to the modelled geological boundaries where boreholes prove that a unit extends beyond its mapped distribution.

The start heights (recorded ground level) of borehole logs were honoured during cross-section construction.

Extensive superficial deposits are mapped in the area, including clay with flints, head and river terrace deposits. However, these have not been modelled. Instead, the bedrock units are modelled up to the Digital Terrain Model (DTM), which makes them slightly thicker than in reality where they are modelled at the ground surface.
