Results of time–temperature modelling with HeFTy (Ketcham 2005) for a crystalline basement sample from the bottom of the Benken borehole (for data, see Table 1). The time ranges of the geological periods were taken from Gradstein et al. (2012). The light grey envelope shows the range of time–temperature paths with acceptable fit to the measured age and track length data (GOF >0.05), the dark grey envelope indicates the range of time–temperature paths with good fit to the measured data (GOF >0.5). The thick dotted line indicates the time–temperature evolution as predicted by basin modelling (Müller et al. 2002). The shaded area between 60 and 120 °C indicates the temperature range of the apatite partial annealing zone. Inset shows the magnified time range of the last 20 myr and the shaded area from 5.5 to 2.5 Ma the time range of the inversion from burial to exhumation as predicted by the modelling
