Figure 10

The radiogenic heat production of rocks in the Årvollskogen borehole based on a gamma spectrometry logging. Radiogenic heat production has been calculated according to Rybach ([1988]). The blue plot is the radiogenic heat production obtained from the gamma spectrometry logging, and the red one is calculated by use of running-mean averages at depth intervals of 5 m.
