This virtual borehole and section viewer is based on a prediction of the geological sequence that would be encountered in a vertical borehole or section drilled at this location and should not be used as a replacement for site investigation.

The total depth of the borehole or section and the level to which the succession is subdivided is based on 3D geological modelling and may not represent the complete vertical borehole or section.

Lithological information is generalised for each geological unit, and local conditions may vary.
