Hulbert A G, Terrington R L. 2015. Metadata report for the Weald Basin 1:250 000 resolution geological model. British Geological Survey Internal Report, OR/14/028.

The surfaces were generated from the structural depth contour plots (Chadwick et al., 1983). Well control was not directly used.

Surfaces modelled (Figure 4) are (numbers relate to stratigraphic order):

01 Base Tertiary

02 Base Lower Greensand

03 Top Corallian

4 Top Cornbrash

5 Top Penarth Group

6 Top Variscan Basement
