Table 3 Surface heat flow calculation with the interval method for two well locations

Well	Interval		Γ (°C km⁻¹)	Lith.	λ (W m⁻¹ K⁻¹)	q_interval (mW m⁻²)	q_mean (mW m⁻²)
Well	Nr.	(m)	Γ (°C km⁻¹)	Lith.	λ (W m⁻¹ K⁻¹)	q_interval (mW m⁻²)	q_mean (mW m⁻²)
NB-19	1	74–109	11.0	Dol.	2.6	28.6	47.9
	2	122–158	23.0	Ls. Cong.	2.5	57.5
	3	174–245	24.0	Ls. Cong. Dol.	2.4	57.6
RGS2-L	4	112–180	18.0	Ls	2.5	45.0	46.4
	5	230–267	23.0	Si.	2.2	50.1
	6	271–329	22.0	Si.	2.0	44.0

The intervals are marked with a black bar in Fig. 5. For location of the wells see Fig. 2. The interval gradient (Г) is given in °C km⁻¹, major lithological units of the interval are given (lith.), interval thermal conductivity (λ) is given in W m⁻¹ K⁻¹. Interval surface heat flow (q_interval) and mean surface heat flow (q_mean) are given in mW m⁻²
