From: 2D structural and thermal models in southeastern Norway based on the recently drilled Årvollskogen borehole and 2D density, magnetic and thermal modelling

Figure 17

The Årvollskogen borehole: measured versus modelled temperatures with the results of the sensitivity analyses. The preferable modelled temperature-depth plot is shown by the red colour. The brown line is according to a 20 km shallower lower thermal boundary whereas the green line represents a 20 km deeper lower thermal boundary. The orange line corresponds to the model with a 0.5 μW/m3 higher radiogenic heat production of the upper and middle crust, and the purple line shows a 0.5 μW/m3 lower radiogenic heat production of the upper and middle crust.
