Fig. 9

Area of Carnmenellis granite outcrop, radially extended by 2 km. Continuous colour image of BH-corrected heat production obtained using Eq. (1). A heat production value of 5 μW m−3 is shown as a white contour. Granite outline shown in black and water bodies with cross-hatch. BH locations (crosses) and heat production estimates from Table 1 are shown for comparison. The rectangle defines the quarry area from Fig. 5
