The seismic profile and section shown in Figure 2 is taken across the north margin of the platform. The lack of internal deformation in the Edale Basin sediments is evident in the section and the present basin topography is essentially unchanged from the end of the Visean. Whilst there is no extant thermal modelling of the Edale Basin recent work has been done on the Widmerpool Gulf to the south of the Derbyshire Platform. This is part of ongoing assessment of the shale gas resource potential of the Bowland-Hodder unit. For the Widmerpool Gulf a maximum burial depth of 3.6km for the base of the Bowland-Hodder shale unit is estimated to have been reached at the Carboniferous-Permian boundary. A high
modelled heatflow in excess of 70$\mu$W.m^{-2} resulted in a geothermal gradient of close to 50$^{\circ}$.km^{-1}. Maximum temperatures at the base of the basin were close to 200$^{\circ}$C (Anderson, 2013).
The maximum burial depth for the platform is somewhere between 1 and 2km with considerably lower temperatures. V
