Following the Beardsmore Protocol, the temperature at 1 km was first calculated based on surface heat flow (corrected for paleoclimate), mean surface temperature (mean annual air temperature), the thermal conductivity structure of the 2-layer model (thickness-weighted and temperature-corrected harmonic mean of all the formations in the sedimentary section) and the heat production within the sedimentary layer and basement (thickness-weighted arithmetic mean of all the sedimentary formations). Thermal conductivities of individual formations were taken from Rollin (2002). The temperatures at the mid-point of each 1000 m depth interval from 3000 m to the base of the model at 9500 m were then calculated, assuming heat conduction only and accounting for the decrease in radiogenic heat production with depth.
