The modelled surfaces were directly constructed from the structural contours from the Weald Report and then warped to fit borehole data points (not using the Structural modelling workflow).&lt;br /&gt;
&lt;br /&gt;
The Top Penarth Group surface was constructed from isopach values. Values were gridded in Arc GIS and then added to the Top Variscan Basement surface to produce depth values. The depth values were then exported and used in the modelling process as normal.&lt;br /&gt;
&lt;br /&gt;
The Isle of Wight monocline is presumed to be unfaulted for Cretaceous and younger rocks. More recent studies have shown this not to be the case (Evans et al., 2011)&lt;br /&gt;
&lt;br /&gt;
As part of the modelling process, crossovers may occur between the surfaces. Some of these are directly the result of contours overlapping in vertical space. These have been resolved wherever possible but still may exist in some places.&lt;br /&gt;
