  1. 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 (qinterval) and mean surface heat flow (qmean) are given in mW m−2
