Geothermal plot comparison between temperature-dependent thermal model and extrapolated temperature range untaken by Danis et al. (2012) shown by the purple outline. The temperatures reported by Danis et al. (2012) are based on measured equilibrated temperatures at specific borehole locations. Our models show the effect of coal measures on the local geothermal gradient, but are not able to replicate the same measured temperatures reported by Danis et al. (2012). The large-scale blanketing effect of coal seams result in a net increase in modelled temperatures at depth, despite both models starting at the same surface temperature
