2. Map of NE England showing the principal geological features and selected deep boreholes.
Map of NE England showing the principal geological features and selected deep boreholes. Contours, in kilometres below Ordnance Datum, indicate the upper surface of the North Pennine Batholith (after Kimbell et al. 2010). The larger inset map shows the location of the Science Central Borehole site in central Newcastle upon Tyne in relation to numbered public highways.

6. Bullard thermal resistance plot calculated for depths below 500 m in the Science Central Borehole.
Bullard thermal resistance plot calculated for depths below 500 m in the Science Central Borehole. Linear regression has been applied to sections of the plot corresponding to the upper, middle and lower sections of the borehole.
